• Why? To expand the familiar and proven Geolog technology into additional phases of the production cycle

• How?1. Well schematics2. Well integrity3. Production log interpretation

GEOLOG

New Engineering Modules


Geolog Engineering Modules

1. Well schematics− New well schematic editor/well

schematic track in layout

2. Well integrity− Casing thickness, metal loss, etc.− Customized reporting utility

3. Production logging− Interactive picking of flowing zones− Automated flow rate/volume calculation


1. Well Schematics

• Visualize wellbore mechanicals in conjunction with all other data gathered from the wellbore− Casing (and cement)− Tubing− Perforations

• Create new well schematics using the new editor, or display existing completions in the new schematic track

6

Provides critical input to cased hole logging applications


2. Well Integrity

• Geolog provides an independent means of assessing the mechanical condition of casing in a wellbore− Interpret casing inspection logs: collar location and

QC, results visualization and analysis per joint− Calculate casing quality: Metal Loss, ovality, min/max

diameter, Burst Pressure, Collapse Pressure, Axial Tension, third-party equations, etc.

− Generate reports automatically with customizable templates: summarize results and highlight areas of concern

Ensure safe well operations and ultimate abandonment of a well


3. Production Logging

8

• Process and interpret spinner and fluid tools to identify volumes of fluid produced in their wells

• Calculate fluid volumes flowing from completion zones

• Working with this data directly alongside open hole datasets can enhance interpretation and understanding of the producing reservoir

Evaluate performance of wells on a zone-by-zone basis


B. Minimize Drilling Cost While Ensuring Safety

9

• Why? • To determine optimally stable well drilling parameters• To improve recovery and reduce exploitation costs

• How?1. Pore Pressure Prediction2. Dynamic and static elastic properties3. Unconfined compressive strength4. In-situ stress estimation (multiple methods)5. Wellbore stability plots

Published algorithms and ability to easily add custom relationships for all steps

GEOLOG

Full-function Geomechanics Module


Geolog Geomechanics Module

• GM module provides a comprehensive series of calculations and interactive tools to assess wellbore conditions− Helps understand regional stress orientations

and magnitudes and how they affect rock properties in formations around a wellbore

− Essential for ensuring well stability and assessing optimal orientation for fracture development

10


Geomechanics as a Tool for All Domains

• Geomechanics is used by:− Geologists and petrophysicists

• To estimate hydrocarbon column heights• To estimate fault seal potential

− Drilling engineers• To determine optimally stable well drilling trajectories• To determine casing set points and mud programs

− Reservoir engineers• To understand changes in reservoir performance during depletion• To improve recovery and reduce exploitation costs

11


1. Pore Pressure Prediction• Why Pore Pressure Prediction?

− Drilling safe wells• Wellbore stability• Casing/mud program design• Risk & cost reduction• Cost related to abnormal pressure: Potential $ billions

–Blow-out/kick–Stuck pipe–Lost well/lost lives

− A first step in reservoir geomechanical studies• Estimation of regional stresses• Seal effectiveness


1. Pore Pressure PredictionDrill safer wells; provides critical input to reservoir geomechanical studies

• Independent pre-drill validation ofpore pressure within the familiarGeolog environment− Workflow consolidated into one integrated

Loglan− Many new options and methods for inputs,

compaction trends, gradients, etc.

• Provides input (overburden pressure,etc.) for other geomechanics workflows


• Compute dynamic elastic modulifrom logs

• Convert dynamic to static usingpublished or custom regressions

• Static properties used to calculatebrittleness, etc.

2. Dynamic and Static Elastic PropertiesProvides critical input to completions planning


• Compute UCS from logs• Includes 23 published Dynamic to Static

UCS corrections and 8 standard equation forms that allow user to specify coefficients derived from crossplots

3. Unconfined Compressive StrengthProvide critical input to completions planning and in-situ stress assessment


• Used to evaluate fracture propagation direction− Estimate in-situ stress magnitudes− Use output from PPP module or new log- and

fluid-based methods− Overburden, min and max horizontal stresses− Azimuth of Shmax (calibrate with image logs)

4. In-Situ StressProvide critical input to wellbore stability workflows


• Converts stress logs into mud-weight-equivalent pressures

• Graphic presentation of safe drilling window defined at the lower limit by pore pressure and at the upper limit by fracture gradient

5. Wellbore Stability: Mud WindowPlan safer mud program: avoid kicks, lost circulation, etc.


• New plot works in either calculator mode (single inputs) or log data mode (scrollable)

• Indicates conditions (inclination, azimuth, mud weight, etc.) under which borehole breakouts and tensile fractures will form

5. Wellbore Stability: Stress PlotInvestigate interactively wellbore conditions that could lead to failure


• Always works in calculator mode• Shows maximum stress for all

possible wellbore directions• Easily switch between multiple

failure modes: min/max mudweight, breakouts, rock strength

5. Wellbore Stability: Stereonet PlotInvestigate interactively the wellbore stability under any drilling direction


C. Enhance Productivity and Efficiency

20

• Why? • Provide smoother and more efficient workflows to cross-disciplinary asset teams• Enable petrophysicists and engineers to identify specific flow units within reservoirs

and estimate their flow capacity• Leverage best-in-class wellbore data analysis platform for geological interpretation
