1Introduction

About QUE$TORQUE$TOR is a project modelling, evaluation and decision support system forglobal application in the oil and gas industry. It uses a systematic approach togenerate a field development basis, capital and operating costs, and projectschedules. This systematic approach allows engineers, estimators andeconomists to produce weight and cost estimates quickly, consistently andaccurately and to develop investment profiles.

QUE$TORs comprehensive capability, flexibility and ease of use have benefits inmany applications including:

Prospect Evaluation

Screening Studies

Feasibility Studies

Conceptual Studies

Optimisation Studies

The ability to produce cost estimates from basic reservoir data provides formeaningful prospect evaluation and facilitates investment decisions. The abilityto refine QUE$TORs assumptions and defaults allows detailed estimates to beproduced suitable for use in conceptual and optimisation studies.

The use of separate cost and technical databases for all major worldwide oil andgas producing regions means that any development, present or future, can bemodelled.

You can also guarantee an up-to-date estimate based on the latest economic andsupply situation due to regular updates to the cost databases.

Professional-quality printed outputs can be produced for inclusion in managementlevel reports including overall summaries, component costs, technical inputsheets, schedules and the base data used to build up each estimate.

QUE$TOR Capabilities

QUE$TOR has the capability to handle both offshore and onshore projects.

Offshore Capabilities

The offshore portion of QUE$TOR incorporates all stages of offshore fielddevelopment, from appraisal drilling, through to hook-up and commissioning(HUC) of installations, operations to decommissioning. All types of developmentare covered from single subsea well tie-backs connected to existing platforms, tomajor complexes consisting of platforms, support structures, pipelines andoffshore loading systems.

In generating capital cost estimates for a field development, the estimate isbroken down into a number of discrete components. Combining thesecomponents allows a field development plan to be identified and estimated. It is

then possible to generate operating costs for the facilities specified and phase theexpenditures as necessary.

Onshore Capabilities

The onshore portion of QUE$TOR incorporates all stages of onshore fielddevelopment, from appraisal drilling, through to construction of installations andoperational costs. All types of development are covered from single wellpads tiedback to an existing production facility, to major complexes consisting ofproduction facilities, terminal facilities, pipelines and all associated infrastructure.

In generating capital cost estimates for a field development, the estimate isbroken down into a number of discrete components. Combining thesecomponents allows a field development plan to be identified and estimated. It isthen possible to generate operating costs for the facilities specified and phase theexpenditures as necessary.

Combined Capability

Combining the offshore and onshore portions of QUE$TOR makes it possible tomodel a field development that is split between offshore and onshore e.g. atopsides can be tied back to a terminal facility, or the wells could be in bothoffshore and onshore locations.

LNG Capability

The LNG portion of QUE$TOR is in development. The QUE$TOR 9.7 releaseincorporates onshore LNG regasification terminals.

The LNG regasification terminal can be costed on its own or with other onshoreand offshore components, but requires a separate licence and either an onshoreor an offshore licence.

Contacting Customer SupportAs part of the continuing licensing agreement for QUE$TOR, IHS offers a fulltechnical support service via its London, Houston and Singapore offices. Bothcomputing and engineering support relating to the operation and understandingof the program are available.

5Quick Start Guide

About the Quick Start GuideThis guide is designed to help you understand the basic operation of theQUE$TOR program, allowing you to develop a QUE$TOR project and produce ascheduled estimate for capital and operating costs.

Getting Started

QUE$TOR must be installed on a local PC. This must be done by a localadministrator. See the release notes for installation instructions.

A licence must be available; either a standalone dongle which plugsdirectly into your computer or a network licence which is accessible acrossyour company network. Contact your IT department for further details.

QUE$TOR can be run either from the QUE$TOR icon on the desktop or byselecting the program from the Start menu following All Programs \IHS\QUE$TOR 9.x.

Button Terminology

Apply accepts the changes on an input sheet and recalculates thecost sheet to show the impact of that change.

OK applies changes to the input or cost sheet, closes the form andupdates all dependent values elsewhere in the program.

Cancel closes the form or cost sheet without saving any changesthat have been made.

Project Properties The project properties allow you to setup the basic information about your

project, the procurement strategy, regional technical database and unitsset you will be running the project with.

On start up select if you wish to create an onshore project or an offshoreproject, see below. You also have the option to open an existing project,there are shortcuts to the last five projects opened in QUE$TOR. Thelocation of your wells determines whether you pick offshore or onshore asthe start point. Later at the field development schematic stage, you mayactivate the alternate licence to develop a combined offshore plus onshoreproject.

QUE$TOR Help

QUE$TOR checks you have a valid licence to run the selected project type,i.e. offshore or onshore, and if you do opens the Project properties form.

Give your project a name.

Select the units you want to work in. Pick from one of the standard unitsets provided or create your own using the Unit Editor tool, see below.

Select the main product, Oil or Gas, see below.

Select the geographical region, country, and basin to enable QUE$TOR toseed your project with typical basin specific data analyzed from the IHSIRIS21 E&P database, see below.

Create your procurement strategy by clicking the New button. The formbelow is displayed. Procurement strategies allow you to choose differentregional cost databases for each cost centre. This is similar to theprocurement strategy in QUE$TOR Onshore version 7.9.

Quick Start Guide

7

By default all costs are reported in US Dollars.

The procurement strategy also allows you to change the databasecurrency from US$ into the currency of your choice.

The technical database for the project defaults to the most appropriateregion for the country you have selected. Use Browse to select analternative if required.

To create an LNG regasification terminal only project ensure the Proceeddirectly to field schematic is checked.

Field Level Data EntryAll the data on the next screen is categorized as field level data. It has beenpopulated from the basin database you have selected. To modify any inputvalue, simply overwrite with your own data. The information entered variesslightly depending on whether you have selected an offshore or onshore project.The field level data form for an offshore oil project is shown below. Thisinformation is not required if creating an LNG regasification only project.

QUE$TOR Help

Creating a Production ProfileSelect field life and plateau data to produce the production profile, see below.

QUE$TOR Help

10

The default production profile is displayed.

Copy and paste in your own data or adjust until you have the profile thatyou require. When using cut and paste ensure the field life agrees with theimported profile. You may change the display to daily, annual orcumulative production using the graph dropdown list.

Follow through the next steps to calculate the number of wells andproduction capacity.

Select Your Field Development Concept - OffshoreQUE$TOR selects an appropriate field development concept based on the fieldlevel data and production profile. You can change this to another of the 14default concepts using the list box.

QUE$TOR also selects typical oil and gas export options.

Quick Start Guide

11

You can configure your own field development plan (select Blank) or select one ofthe standard development concepts and modify it if required using the QUE$TOROffshore components

When you select one of the 14 standard development concepts and click the OKbutton QUE$TOR runs the complete cost estimate using program defaultsthroughout and displays the field development schematic along with the costsummary tree.

Component Level DataTo review and/or adjust the default input values used to generate a componentcost, double click the icon in the field development schematic. This displays theinput data and the cost sheet for the selected component, see below.

Quick Start Guide

15

Input and output screens have now been standardised between the components.

The left hand side contains all the input data for that component. The arrowbuttons allow you to move quickly around the calculation process withouthaving to go through each step sequentially.

The icon opens up more detailed calculation forms as a separate view.

QUE$TOR Help

16

If you overwrite a value it is considered to be locked in subsequent calculations.

Is how it appears on the cost sheetwhen locked.

The locked item on the input sheetappears bold with a small padlock alongside it.

Operating CostsOperating costs may be accessed by selecting OPEX from the Project menu. Asummary of the operating costs for each year of production is displayed.

Quick Start Guide

17

A more detailed breakdown of these costs can be obtained by clicking on theitems in blue hypertext type. This will open up further definition sheets for you toreview or adjust the default values.

SchedulingThe Scheduling module can be accessed by selecting Scheduling from theProject menu.

You can lock a component schedule by right clicking on the component name, re-adjust the capital cost and apply the revised costs to the saved schedule. Thisintroduces much more flexibility than QUE$TOR version 7.9.

You can specify the cost vs. duration distribution of each activity. Fourdistribution types are available; uniform (UNI), down payment and delivery(DPD), triangular (TRI) and user entered (User). To view and adjust thesedistributions by activity click on the relevant Dist cell.

QUE$TOR Help

18

The CAPEX tabular data is calculated on a yearly, quarterly or monthly basis andcan be viewed or exported to Excel from the breakdown chart form.

Investment and Production ProfileThe investment and production profile is accessed by selecting Investment andproduction profiles from the Project menu.

Operating costs and production profile reflect when first oil occurs (as defined inscheduling). If first oil occurs part way through a project or calendar year thenthe profiles are adjusted accordingly.

Editing UnitsYou may use the standard units databases provided with the program or you cancreate and use your own units sets. To create your own units set or open anexisting unit set, the unit editor can be accessed using the Start menu followingAll Programs \IHS \QUE$TOR 9.x \Unit editor. Or select Unit editor fromthe Tools menu of QUE$TOR.

You may create your own custom set of units, see below. This set can be savedand used as a custom unit set when creating a new QUE$TOR project.

Quick Start Guide

19

A mouse click on any unit when running the program allows on-the-fly changing,see below.

QUE$TOR Help

20

The current unit is shown in bold on the list of available alternatives.

Database EditorThe database editor allows you to create and view/edit both procurementstrategies (cost databases) and the regional technical databases. It can beaccessed using either All Programs \IHS \QUE$TOR 9.x \Database editorfrom the Start menu or from the Tools menu when QUE$TOR is running.

Note: Any changes made to databases will not be reflected in any existingprojects that use those databases. Only future projects will pick up the changes.

Warning: Care is required when editing procurement strategies and technicaldatabases. These databases are used to drive QUE$TOR and it is possible tomodify them so that QUE$TOR no longer functions correctly when the modifieddatabases are used in a project.

On entering the database editor you are given two options. You can eitherview/edit an existing database or create a new database using one of the existingdatabases as its template.

Quick Start Guide

21

You then select which type of database you want to view or create; offshore,onshore or LNG and procurement (cost) or technical.

There are 17 regional offshore databases and 11 regional onshore cost andtechnical databases to choose from as a template when creating a new database

If you select Modify an existing database a form similar to the one shown below isdisplayed allowing you to select the database you want to open

QUE$TOR Help

22

On opening the required database the form is displayed

To select a table you must choose the Item type, Component type and the Tabledescription

The Toolbar buttons provided to help you search through a database, plus log,print and save changes.

Quick Start Guide

23

Some tables contain several columns of values, e.g. equipment, topsides, gascompression turbine data. If there are a number of columns some may not bevisible without scrolling across. To maximise the amount of data that can beseen without having to scroll you can use Scale data column width slider to adjustthe relative width of the data columns

If the Show audit information check box is ticked then two more columns (orrows depending on the format of the selected table) are added to show whoedited the data plus the time and date when the last change was made

Project EditorThis feature allows users to adjust the regional cost and technical data of acompleted project without recreating the project. The project editor can beaccessed through the Start menu All Programs \IHS \QUE$TOR 9.x \ProjectEditor.

On running the project editor you must choose which project to adjust.

The program then shows which databases are being used within the program.You can then browse alternative databases a select a new database for theproject.

QUE$TOR Help

24

Saving the project then overwrites the original databases with the new selections.

LockingThis feature was introduced in QUE$TOR version 8.0 to give flexibility in savinginformation and recalculating projects.

A locked item is an item that you have overwritten. It is locked to the program.The value is shown in bold and there is a padlock symbol to the left of the valueentry box, see below. During any recalculation, a locked item will not beoverwritten by QUE$TOR. This allows you to modify individual data points andstill be able to recalculate and retain these items. You may change the lockeditem by typing in a new number. It is not necessary to unlock it first.

You may unlock the data item with a right mouse click and the program willrevert to the previous input value prior to your change.

A new project can be created when a project is open, to do this select New

project from the File menu or click on the New project button on the utilitiestoolbar. You will be asked if you wish to save your existing project beforecreating the new project via a similar task selection form.

Note: Projects are not saved automatically. You can save a project byselecting Save from the File menu once you get to the Field developmentschematic. When you create a new project you won't be able to do this until youhave stepped through all the initial forms.

Saving a Project

Projects are not automatically saved in QUE$TOR. To save a project select Saveor Save As from the File menu. This will enable you to save the project in theusual windows fashion. The default location for saved projects is MyDocuments\IHS\QUE$TOR\Projects.

Saved projects include the selected procurement strategy, technical database andunit set. Once saved, projects are completely standalone and have no furtherinteraction with QUE$TORs databases. This means that saved projects can easilybe sent to others who may not have the same databases.

Saved projects can be moved, copied and renamed using Microsoft WindowsExplorer in the same way as any Windows file. Projects can be opened eitherdirectly from Windows Explorer or from within QUE$TOR. To open a savedproject in QUE$TOR either select Open existing project from the form thatappears when QUE$TOR starts or select Open from the File menu.

Opening a Saved Project

To open a saved project select, using the option buttons, Open existing projectand click OK to proceed. This will enable you to open a project in the usualwindows fashion. The Open existing project box has shortcuts to the last fiveprojects opened in QUE$TOR. Saved projects have a .QPR file extension.

Project MenusThis section describes the actions of the commands and operations available fromthe drop down menus above the field development schematic (FDS) when aproject is open. Menu options are greyed out when not available.

The utilities toolbar provides a shortcut to many of the menu commands. Whereavailable, the relevant button is shown next to each of the commands listedbelow.

QUE$TOR UnitsFor every input QUE$TOR provides a choice of relevant units. You can changethese units by clicking on the unit and selecting from the list displayed. Changingthe unit selected will convert the value in the cell in to the new unit.

The default units to be used within a new project can be chosen in the projectproperties. Three unit sets are available by default: metric, oilfield and imperial

QUE$TOR ships with three built-in unit sets: Oilfield, Imperial and Metric.

You can also define their own unit sets using the unit editor.

Form Controls and ConventionsQUE$TOR has been developed for a Microsoft Windows environment andconsequently uses familiar Windows conventions for program operation.

Forms are used extensively for data entry throughout QUE$TOR. They followstandard Windows conventions, which are summarised briefly below.

Ghosting of Drilling ComponentsThe ghosting options in QUE$TOR allow users to ignore the CAPEX and/or OPEXof the drilling components in a project, while maintaining the technical algorithmsfor data flow to downstream components. This feature has been introduced toassist users whose costs are produced independently to QUE$TOR.

The ghosting options can be looked at on a component by component basis orthey can be applied to all future drilling components used in the current projectand future projects.

The overall ghosting options can be accessed through the Tools menu, clickingon Ghost options will open the QUE$TOR ghost options form.

The ghost options form allows the ghosting defaults to be specified. Theselections made will influence all future drilling components within QUE$TOR butwill not affect any components in an open project.

Note: In order to make changes to an existing project each drillingcomponent will have to be changed individually. See below

The ghosting options for a single drilling component can be edited by rightclicking on the component. This will display a drop down where Ghost CAPEX andGhost OPEX can be selected or deselected.

QUE$TOR Help

Ghost CAPEX

When Ghost CAPEX is selected for a drilling component the capital cost of thecomponent is ignored, with the technical parameters still shown. This results inthe following:

The component changes appearance, it will be greyed and paler.

Remove the CAPEX estimate from the cost tree on the left hand side of thescreen. The QUE$TOR cost estimate can still be seen by going into thecomponent.

No capital cost is shown for the component in any of the summary reportsgenerated by QUE$TOR, component reports still show the calculated cost.

The capital cost is passed through to OPEX for calculation of the insurancecosts, which are based on a percentage of CAPEX.

Note: If insurance costs not are required in the OPEX or you want tochange the value then you should manually remove or change the drilling cost inthe first year of the Insurance sheet within OPEX

No capital cost for the component is passed through to scheduling,however the component can still be scheduled.

No capital cost for the component is passed through to the investment andproduction profile.

Ghost OPEX

When Ghost OPEX is selected for a drilling component the operating cost of thecomponent will be ignored. This results in the following:

No OPEX costs for insurance or well workover are calculated

Data Flow and Locking

About Data Flow and LockingCost estimates in QUE$TOR are made up of a number of individual componentssuch as topsides and jackets. Each of these components will influence or bedependent on the design of associated components, e.g. jacket design isdependent on its associated topsides. Components are linked or docked to thosecomponents from which they require data. There are also high level parametersdefined within QUE$TOR, such as reserves, which influence all components.

In generating a cost estimate QUE$TOR calculates one component at a time andthen passes all requisite data onto the next component. The order of this isdefined by the calculation hierarchy. The concept selector generates a basicdevelopment plan from a selection of built-in defaults. The components selectedby the concept are then run in the hierarchy order to provide a developmentcapable of handling the wells and production defined in the production profile andfield level data.

If you wish to fix parameters within a component, preventing them from beingrecalculated by the program, you can lock them.

Data Flow between ComponentsThe data flow between components is defined by a calculation hierarchy. Thisdefines the order in which components are calculated and is illustrated below.Data is automatically passed to components lower in the hierarchy, i.e. data inlevel 1 (field level data) is automatically passed to level 2 (production profile) andto all other levels. Data is not generally passed in the opposite direction althoughthere are cases where it is, these are listed below.

Changing any variable or component will automatically change all variables andcomponents below it in the hierarchy e.g. a change to topsides weight will changethe jacket cost.

The one exception is the concept selector where the concept must be manuallychanged. Changes to the field level data or production profile are still passedautomatically to all components below the concept selector in the hierarchy, e.g.changing the plateau production rate will change the production capacity of thetopsides. However, if changes to the field level data or production profile result ina change to QUE$TORs default concept the concept will not be changed until youenter the concept selector and manually select the new concept.

Changing the concept will delete all components and create a new set ofcomponents.

Note: When you change the concept you will lose any changes you havemade to the components in the original field development plan

QUE$TOR Help

Exceptions to the hierarchy order

Oil and gas export: oil export pumps and gas export compressors aredependent on the pressure drop in the export pipeline. The export pipelines aresized first and changing the pipeline diameter will automatically recalculate thepumps or compressors.

Multiple topsides

QUE$TOR uses a logical technique in passing flowrates between multipletopsides. The topsides must be linked with appropriate pipelines before any datais passed between them, for example gas lift flowrates wont be passed betweentwo topsides unless they are linked by a gas lift pipeline.

When two topsides are linked by a pipeline they look at the pipeline direction (asdefined in the pipeline component) to work out which direction the flows aretravelling in. Data is then passed in the direction of production. Increasing theoil flowrate on a wellhead platform tied back to a processing platform willincrease the capacity on the processing platform. Similarly increasing the gasinjection on a wellhead platform receiving gas injection from a main platform willincrease the gas injection capacity on the main platform. These relationships donot apply in reverse. See Well flow and distribution for further details.

Data Flow Within ComponentsMany of component inputs influence other inputs within the component. Usuallythis is relatively simple, for example the number of storage days for a tanker willaffect the tanker size chosen. Data flow between these types of inputs alsofollows a calculation hierarchy. Changing the number of days storage requiredwill dynamically update the tanker size but changing the tanker size will notupdate the number of days storage. These types of relationships are explainedindividually for each component in the help sections covering component inputs.

The data flow between topsides facilities is illustrated below. The flowchart isdesigned to give a broad view of the relationships between sub-components. Anychanges to a sub-component may affect all sub-components downstream of it inthe flowchart. This does not apply to every parameter of a sub-component andneither does it mean that every downstream sub-component will be influenced bychanges to an upstream component.

QUE$TOR Help

42

LockingAny calculated variable in QUE$TOR, whether on the cost sheet or in the inputscan be locked. Locking a variable will prevent it from being recalculated by theprogram. For example locking the steel weight in a jacket will prevent it frombeing recalculated if you add or remove systems from the associated topsides.

It is important to note that you can overwrite locked values at any time. Interms of QUE$TOR a locked value is one that will not be changed by theprogram; you can change it freely.

Variables can be locked by right clicking on them and selecting Locked.Variables are locked automatically if you change them. They can be unlocked byright clicking on them and de-selecting Locked. When you do this they willrevert to the values calculated by the program.

Locking should be used with care to ensure that you dont lock values based onincorrect data. For example the power demand in a topsides is calculated byadding the power requirements of all processes on the platform. If you changedthe model of turbines selected and locked them before adjusting other topsidessystems you may be basing your turbine selection on an incorrect power demand.

To avoid this you should follow the calculation hierarchy. When adjustingprojects: start with the highest level inputs (field level data) and work down tothe lowest (scheduling).

In some situations you may wish to input your own data and ignore QUE$TORscalculations and so QUE$TOR does allow you to enter data in any order.

QUE$TOR Structure

QUE$TOR is structured around a field development schematic (FDS) which allowsusers to create a visualisation of the development. The FDS is driven by anumber of high level inputs which allow the development conditions to bespecified. The basic program calculation sequence followed in QUE$TOR togenerate a full life-cycle field or prospect development cost estimate is shownbelow.

To define the new project, QUE$TOR presents you with a series of forms thatallow high level parameters of the development to be specified. Once you have

reviewed and adjusted as necessary the default inputs in each form, click on OKto apply the inputs and move on to the next form. Click on Cancel to go back tothe previous form and adjust any changes made.

On starting each new project you will be led through the first four stages shownabove. Each of these stages will be populated with default values based uponyour choices in the previous stage.

When the concept selector is completed, QUE$TOR will generate a complete costestimate immediately made up of a series of components, e.g. topsides, jacket,drilling and pipelines.

These components are all live linked to each other so that a change to onecomponent will change all dependent components, e.g. jacket cost is dependenton topsides operating weight. You can enter and update these components andfix inputs so that they are no longer updated by the program. This is calledlocking. Although you can edit components in any order you should try to followa logical path to avoid locking variables based on incorrect data. For exampleyou should not lock the jacket weight until the topsides is fully defined.QUE$TORs order of calculation is explained in further detail in Data flow andlocking.

OPEX and Scheduling take data from all components to generate field operatingcosts (OPEX) and schedule the calculated capital and operating costs along withthe production profile to give an overall project investment profile.

Custom unit sets can be defined using the unit editor. To select a user definedunit set, select the use custom unit set option button and use the Browse buttonto locate it. The default location for custom unit sets is: My Documents \IHS\QUE$TOR \Procurement Strategies.

Once in a project the units can be easily changed, for every input QUE$TORprovides a choice of relevant units. However the units in the reports are fixed bythe choice of unit set.

Main Product

The main product can be either oil or gas, the volume of the secondary product,e.g. associated gas when oil is selected, is defined by a ratio on the Field leveldata form.

The default product type is set to the choice made in the last project you created,or to oil when QUE$TOR is shipped.

Location

QUE$TOR contains a database of typical field characteristics, extracted from theIHS IRIS21 E&P database. These are broken down on a basin by basin basis andprovide the default properties for the field. Whilst you can overwrite all thesecharacteristics, they can be useful if some data is unavailable.

Procurement strategy

This allows you to select the regional databases to be used for each of the costcentres for the new project. For example equipment could be sourced from NorthAmerica and design performed in Europe. The currency of the cost estimate canalso be defined.

The box displays existing procurement strategies which can be chosen byselection.

Creating Procurement Strategies

Procurement strategies allow you to choose different regional cost databases foreach cost centre. They can also be used to choose the currency for the costestimate. The cost data in each regional database is stored in either US dollars orthe local currency (for the UK, Norway and the Netherlands). When costdatabases are brought in to the procurement strategy QUE$TOR converts themall in to US dollars. You can edit the exchange rate used for this conversion. Youcan then choose a currency for the cost estimate and enter the exchange ratefrom US dollars to this currency.

7. Check the exchange rate for each database. Some cost databases are inlocal currencies. In creating a procurement strategy QUE$TOR converts allcosts to US dollars. A default exchange rate is entered if the cost database isin local currency but this should obviously be treated with care and edited toreflect expected exchange rates. The rate should be in the form of localcurrency to 1 US dollar, e.g. UK0.55 = US$1.

8. Define the currency in which you wish to cost your project. Enter a nameand a symbol (the symbol can have up to three characters). Enter anexchange rate from US dollars. The rate should be in the form of thespecified currency to 1 US dollars, e.g. UK0.55 = US$1.

Reserves: the total recoverable reserves for the field(s) covered by yourproject. If you have specified the main product as gas, this is the gasrecoverable reserves. For oil projects it is the oil recoverable reserves.

Condensate gas ratio / Gas oil ratio: for gas projects enter thecondensate gas ratio (CGR) and for oil projects the gas oil ratio (GOR).The ratio should be in terms of recoverable reserves and is used todetermine the reserves and production profile of your secondary productbased on those of the main product.

Reservoir depth from LAT: measured from the lowest astronomical tide(LAT) and is used to calculate drilling costs.

Reservoir pressure: used in calculating wellhead and injectionpressures.

Reservoir length and Reservoir width: used in conjunction with themaximum drilling stepout to calculate the number of drilling centresrequired to fully drain the reservoir.

Water depth: measured from the lowest astronomical tide (LAT) andstrongly influences the development concept chosen.

Fluid / Profile Characteristics

The fluid/profile characteristics tab is shown below.

QUE$TOR Offshore

Liquid data

Oil density: the crude or condensate API at stock tank conditions is used inconjunction with the GOR/LGR and the gas molecular weight to generate apseudo composition for the wellstream fluid. This is used in the topsidescomponent for sizing the separators.

Gas data

Gas molecular weight: used to define the gas composition in the oil andgas processing modules of the topsides.

Note: The gas molecular weight entered is for the hydrocarbonplus acid gas components. If you change the default acid gascontent you should considering adjusting the gas molecular weightas increasing the acid gas content without increasing the gasmolecular weight effectively decreases the molecular weight of thehydrocarbon portion of the gas.

CO2 content and H2S content: the gas H2S and CO2 contents are usedin the topsides component for selection of the materials (carbon steel orstainless steel), corrosion allowances and the gas sweetening option.They are also used to choose casing, conductor and Xmas tree costs indrilling. Here stainless steel is used in preference to the cheaper carbonsteel if CO2 content is greater than 3%.

Well data

Productivity: used to generate the production well count and relates tothe total production of a well over the field life.

QUE$TOR Help

54

Peak well flow: used to determine the plateau production rate which isalso based on the percentage of reserves extracted at peak and estimateddrilling durations. The peak well flow should be entered on a daily basis.

Miscellaneous

Miscellaneous Items

Distance to operations base: used to determine the cost of logistics(transportation of men and consumables) in OPEX.

Distance to delivery point: used in the concept selector to determinethe export route and whether or not a subsea or wellhead tie-backdevelopment is viable.

Maximum drilling stepout: used in conjunction with the reservoirextent to determine the number of drilling centres required to drain thewhole of the reservoir.

Production Profile

About Production Profiles

The production profile opens after the field level data if you are creating a newproject, if you are in an existing project you can open it by selecting Production

Profile from the Project menu or clicking in the toolbar.

The production profile consists of a series of four forms which allow you to definethe production profile as well as the capacities of your facilities and the number ofwells.

Once you have completed adjusting each form click OK. This applies yourchanges and closes the form to move on. Cancel will clear all entries in the formand take you back a step.

Production Profile Edit

QUE$TOR will generate a default profile based on the reserves, well productivityand well peak flow rate. The initial ramp-up duration is calculated based on 8wells being drilled a year whilst plateau production is assumed to last until 55%of the recoverable reserves have been produced. QUE$TOR assumes that thefield will be on-stream for 350 days a year, allowing for an annual two weekmaintenance period. The production profile edit form, shown below, allows youto modify QUE$TORs initial estimates to shape the generated production profileas required.

Once these values have been adjusted, click OK to progress to the productionprofile. You can still go back to the production profile edit form by clicking onModify Profile below the production profile.

QUE$TOR Help

56

Production Profile

The production profile form gives the user a visual representation of theproduction profile as specified in the production profile edit form.

The production profile is displayed in a graphical and tabular format. Click on theappropriate tab to display either the liquid or gas profiles. Use the dropdown liststo select which graph is displayed on each tab. The tabular data can beoverwritten either individually or by pasting in a profile from a spreadsheet.

Tip: Ensure that the field life specified in the production profile edit form isthe same as that of the profile you are pasting in. You cannot overwrite thecumulative row of the table. You can also copy the data in the production profileand paste it into an external spreadsheet

If you wish to change the reserves or any other field level data, click on Fielddata to go back to the field level data form.

In an oil project, changes to the oil profile are automatically reflected in the gasprofile (using the input GOR) and similarly with gas projects the liquids profilereflects the numbers input for gas. The reverse is not true, i.e. the oil is not backcalculated if a new gas profile is entered in an oil project.

QUE$TOR Offshore

Note: The daily production rate is based on 350 onstream days, unlessotherwise specified in the Production profile edit form.

To preview a printout of the graphs and tables, click above the Oil and Gas

tabs then click in the print preview toolbar to print the selected graph and

table. Alternatively the profiles can be printed by clicking on above the Oiland Gas tabs. Clicking OK continues with the development configuration.

If the production profile entered results in cumulative production differing by>1% from the total recoverable reserves entered in the field level data a warningwill be displayed when you click OK, shown below. Click OK to continue with theentered profile or Cancel to go back and edit the values. If you continue with theprofile, the recoverable reserves entered in the field level data will be ignored.

Design Flowrates

The design oil and gas processing and injection rates are set on the Designflowrates form, see below. Here the daily average from the peak production yearis brought forward from the production profile. A design factor (for oil projects)or a swing factor (for gas projects) is applied to calculate the design capacityused for equipment sizing. Entering a new design factor or swing factorautomatically recalculates the design rates.

QUE$TOR Help

58

Reservoir pressure maintenance can be specified as either water injection or gasinjection by entering the relevant flowrates. Set the flowrate to zero if it is notrequired.

For oil projects gas injection is selected as the default method of gas disposal ifthe daily associated gas production rate is between 5 and 200 MMscf/day. Waterinjection is selected by default as the means of reservoir pressure maintenancefor oil projects.

The water injection capacity factor is a multiplier applied to the design oilproduction flowrate to calculate the water injection design flow, this defaults to1.2 for an oil project.

Neither gas or water injection are included by default for gas projects.

Number of Wells

The number of development wells form, shown below, provides the estimatednumber of wells required across the field to achieve the specified profile but youcan modify the well count. The default number of production wells is based onthe well lifetime productivity. The default number of water injection wellsassumes an average of two injectors for every five oil production wells. Gasinjectors are based on an average flowrate of 30 MMscf/day per well.

Concept Selector

About the Concept Selector

The concept selector opens after the production profile if you are creating a newproject. If you are in an existing project you can open it by selecting Concept

selector from the Project menu or clicking in the toolbar.

It must be recognised that whilst QUE$TORs default concept selection is veryuseful, the software does not take all the factors into account that wouldultimately influence a final concept selection. In some instances a concept maybe returned that, based on the generic software logic, is very reasonable butwhen compared to your real life field situation might appear somewhatsurprising. Having said that, time and effort has gone into making the selectionprocess as comprehensive and realistic as possible.

Concept Selection for New Projects

The concept selector form, shown below, gives you the option to define your ownconcept or use a predefined concept.

QUE$TOR Help

QUE$TOR will choose a default concept based on the field level data andproduction profile. You can change this to another of the 14 Predefined conceptsusing the list box. Alternatively you can select Blank Concept from the list boxand use the field development schematic to create your own concept. The keyinput parameters that influence the selection most are: hydrocarbon type,reservoir extent, water depth, distance to delivery point, and the number of wells.

The gas export and oil export frames allow you to specify the oil and gas exportmethod from the main platform. Again QUE$TOR will choose a default conceptbut you can select an alternative using the list boxes. Distances to delivery pointshould also be entered for pipeline export to determine length of the exportpipelines.

Once you have completed adjusting the form click OK. This applies yourchanges, closes the form and opens the field development schematic. Cancelwill clear all entries in the form and take you back a step.

Concept Selection for Existing Projects

The Last selected tab is not editable but displays the concept being used byQUE$TOR at that time.

The New tab will display QUE$TORs default concept selection. This may bedifferent to the last selected concept if you have changed the field level data orproduction profile. The New tab also allows you to choose a different concept. Touse the concept selected on the New tab click OK. This will delete all existingcomponents and create a new set of components. To exit without changing theconcept click Cancel.

Note: When you create a new concept you will lose any changes you havemade to the components in the original field development plan.

The concept is never changed automatically. If you make changes to the fieldlevel data or production profile that trigger a change to QUE$TORs defaultconcept the concept will only be changed if you open the concept selector andclick OK on the New tab. A warning is displayed, see below, to caution you thatyou have chosen to replace the current development concept with the newconcept.

The default inputs are designed togive you a reasonable cost estimate in the absence of further data.

The components are all live linked to each other so that a change to onecomponent will change all dependent components, e.g. jacket cost is dependenton topsides operating weight. You can enter and update these components andfix inputs so that they are no longer updated by the program. This is calledlocking. Although you can edit components in any order you should try to followa logical path to avoid locking variables based on incorrect data. QUE$TORsorder of calculation is explained fully see Data flow and locking.

Cost summary tree

The cost summary tree can be seen in the panel to the left of the FDS. Thisdisplays a running total of the total project cost together with a breakdown ofeach component cost. By default, the tree is displayed in expanded format, i.e.for all components the cost for each cost centre is displayed. If you want to seejust the total cost of each component right click in this panel and select Collapseall.

The tree is updated automatically as components are added, deleted andadjusted.

When a component is opened the cost summary tree shows a cost breakdown forthe open component and a total cost for all other components.

Component Toolbar

The components toolbar displays the components which can be used to create adevelopment configuration. There are three tabs available in the componentstoolbar Offshore, Onshore and LNG Regasification. When starting a newproject QUE$TOR will acquire only the licence for the type of development beingcreated. This initial licence is called the primary licence, the example belowillustrates a new offshore project. The green circle indicates the activeprocurement strategies that QUE$TOR is currently using. The example belowillustrates an offshore only project and therefore only the offshore tab has agreen circle.

The Offshore tab displays the offshore components available in QUE$TOR theOnshore tab however will not yet contain any components since the licence hasnot been activated.

To add onshore components the licence must be activated, to do this click Addonshore project. QUE$TOR will locate the onshore licence, when it is locatedthe onshore components will become active and the Onshore tab will now displaythe onshore components.

A green circle has now appeared on the Onshore tab to indicate an onshoreprocurement strategy is selected and is ready to be used.

Note: Once acquired QUE$TOR will not release a licence until the programis closed

Similarly, to add a LNG regasification component, the licence must be activated.To do this click Add LNG regasification onshore project, QUE$TOR willlocate the LNG regasification licence, when it is located the LNG regas onshoretab will become active and will display the LNG regas onshore components.

Some components have a drop down next to them, these can have one of twofunctions:

Some components are available in different variations e.g. a spar buoycomponent can be a caisson, truss or cell spar buoy.

To change the component type selected use the dropdown arrow to theright of the component button, the type selected is indicated by themarker dot.

The components this applies to are: Jackets, GBS, TLP, Spar Buoy,Offshore Loading and Terminal Facilities.

For Topsides, Production facilities and Regasification terminal facilities thisdropdown allows the functions of the component to be defined. This canalso be done within these components.

Field Development Schematic

The field development schematic gives a graphical representation of the projectand allows the selected concept to be refined.

To add components to the FDS

Select a component from the Components Toolbar by left clicking on it. If yourequire a different component type to that selected, use the dropdown button tochange the type before clicking on the component button. Move the cursor ontothe FDS and left click again to drop the component in the required position.

To select a group of components on the FDS

Groups of components can be selected by left clicking with the mouse and holdingdown to drag over all required components before releasing. These groups canbe moved or deleted.

To move a component or group of components

Left click on a component or group of components and hold down to drag to anew position.

To delete a component or group of components

Either select the component(s) with a left mouse click and hit delete or right clickon the component and select Delete. You will be asked to confirm any deletionsto prevent any components being inadvertently deleted.

To open a component

To open and adjust a components cost estimate, double click on it or right clickon it and select Edit/View Cost Estimate. See the relevant component chapterfor more information.

Topsides docking to substructures

Topsides are docked to their associated substructure. This enables the programto pass data needed to size the components between them. It also means thatmoving one of the components will move both components. To dock asubstructure a
