I. Introduction

Connect directly to your Petrel®*

E&P software platform to quickly exchange data, volumes, horizons, cultures, faults, geobodies, layers, color bars and wells with PaleoScan™. If you have the Petrel

® E&P software platform, you can take more advantage of PaleoScan™

interpretation platform by directly sending your interpretation results to Petrel®.

The Petrel® - PaleoScan™ Data Connector is an essential module for Petrel® users who wish to maximize benefits from their PaleoScan™ interpretation. The Petrel® - PaleoScan™ Data Connector is a plug-in extension inside Petrel®, which enables seamless data exchange between Petrel® and PaleoScan™. This data connector is fully integrated in Petrel® and can be launched easily from Petrel® in just a few clicks. It thus saves considerable time in data manipulation. Select any of your 3D volumes, horizons, cultures, faults, and wells – they will be sent instantly in your PaleoScan™ project. Data are fetched from one application and sent to the other one on-demand, with a data connector, showing the two projects databases in their data tree.

This Petrel® and PaleoScan™ Data Connector is developed and distributed by Eliis. Requirements

III. From Petrel® to PaleoScan™

Open the PaleoScan™ Data Connector and select the PaleoScan™ project to visualize the PaleoScan™ database. All the data exchange from Petrel® to PaleoScan™ will be done in the tab From Petrel to PaleoScan. 3D volumes, 2D horizons, 3D horizons, surfaces, faults, cultures, wavelets, well/logs, Well Tops, Color Tables, 3D Objects and 2D Lines data can be exchanged at the same time or separately.

A. 3D Volumes To exchange a 3D volume, select the volume from the Petrel® project browser. Once selected, use the arrow to include the volume in the field “Volume(s)”. The data can also be dragged and dropped directly from the Petrel® project browser into the associated field of the data connector.

To launch the copy of the volume(s), click on the button Run. The other fields corresponding to the horizons, surfaces, faults, cultures, wavelets and well data can also be filled before clicking on Run in order to copy all the data at the same time. In PaleoScan™, the CRS associated to the transferred horizon will be the Petrel® project CRS.

B. 2D and 3D Horizons Horizons interpretation data can be exchanged from Petrel® to PaleoScan™. Only data defined with the Seismic Horizon type can be transferred into a PaleoScan™ project. The horizons can be exported by selecting an interpretation folder from the Petrel® project browser. All the horizons inside this folder will be copied into the PaleoScan™ project. Select the folder from the Petrel® project browser and click on the arrow on the right of the label “Interpretation Folder”. If the given interpretation folder contains other interpretation folders, the PaleoScan™ Data Connector will perform a recursive search to find all the contained horizons and export them. The Petrel® 2D interpretations will be saved as PaleoScan™ 2D horizons, and the Petrel® 3D interpretations will be saved as PaleoScan™ 3D horizons.

Petrel Project Browser

One or several horizons can be exported by using the field “Horizon(s)” of the data connector. Select the horizon to copy from the Petrel® project browser and click on the arrow on the right of the label “Horizon(s)”. Select another horizon from the Petrel® project browser and click on the same arrow to add a horizon in the same field.

The survey associated to the horizon will be integrated to the horizon’s name in the PaleoScan™ data base. If several surveys are associated to a horizon, the PaleoScan™ plug-in will export as many horizons as surveys with the survey name as suffix.

You can mix 2D and 3D horizons. The Petrel® 2D interpretations will be saved as PaleoScan™ 2D horizons, and the Petrel® 3D interpretations will be saved as PaleoScan™ 3D horizons. If your Petrel® horizon contains 2D and 3D interpretation, the Data Connector will create several objects in PaleoScan™:

2D and 3D BCU horizons in Petrel®

BCU horizons in PaleoScan™

2D and 3D BCU horizons in Petrel®

BCU horizons in PaleoScan™



of 30

The attributes associated to the horizon are imported into the PaleoScan™ project

browser. Each attribute will be imported as independent horizon with the attribute

name as suffix.

In PaleoScan™, the CRS associated to the transferred horizon will be the Petrel® project CRS.

C. Regular Surfaces One or several surfaces (object defined with the Regular Surface type) can be transferred by using the field “Regular Surface(s)” of the data connector. Select the surface from the Petrel® project browser and click on the arrow on the right of the label “Regular Surface(s)”. Select another surface from the Petrel® project browser and click on the same arrow to add another surface in the same field. All the objects listed in the field “Regular Surface(s)” will be copied into PaleoScan™ as several independent surfaces.

The regular surfaces are exported into the PaleoScan™ project under the Horizon folder, just as the horizon interpretation data. The Regular Surfaces can be exported by selecting a folder from the Petrel® project browser. All the Regular Surfaces inside this folder will be copied into the PaleoScan™ project. Select the folder from the Petrel® project browser and click on the arrow to the right of the label “Folder”. If the given folder contains other folders, the PaleoScan™ Data Connector will perform a recursive search to find all the contained horizons and export them.

In PaleoScan™, the CRS associated to the transferred surface will be the Petrel® project CRS.

D. Faults The Fault Interpretation data can be exported from a Petrel® interpretation folder. All the faults inside this folder will be copied into the PaleoScan™ project as a single Fault Set. Select the fault folder from the Petrel® project browser and click on the arrow on the right of the label “Interpretation Folder”.

If the selected interpretation folder contains other interpretation folders, the PaleoScan™ Data Connector will perform a recursive search to find and copy all the faults. A Fault Set will be created for each interpretation folder.

The name of the Fault Set corresponds to the interpretation folder name whereas the fault names correspond to the Petrel® naming. These names can be checked from the PaleoScan™ 3D Objects List.

One or several faults can be exchanged by using the field “Fault(s)” of the data connector. Select the fault to copy from the Petrel® project browser and click on the arrow on the right of the label “Fault(s)”. Select another fault from the Petrel® project browser and click on the same arrow to add a fault in the same field. All the faults listed in the field “Fault(s)” will be copied into PaleoScan™ as several independent Fault Sets.

PaleoScan™ - 3D Objects ListPetrel® - Data Base



of 30

In PaleoScan™, the CRS associated to the transferred faults will be the Petrel® project CRS.

E. Well Data Boreholes

The exchange of boreholes from Petrel® to PaleoScan™ includes the copy of associated time to depth relationship, trajectory and well logs for each selected well. The well data can be copied by using the well folder from the Petrel® project browser. All the wells inside this folder will be copied into the PaleoScan™ project. Select the well folder from the Petrel® project browser and click on the arrow on the right of the label “Borehole Collection”. If the selected borehole collection contains other borehole collections, the PaleoScan™ Data Connector will perform a recursive search to find all the wells and export them.

The exported Time to Depth Relationship will depend on the settings of each well. PaleoScan™ plug-in will import the active OWT as time depth relationship.



of 30

The imported well is stored in the PaleoScan™ data base with a specific suffix added to the time depth relation name. This suffix corresponds to the active TDR in Petrel®.

If no TDR is assigned to the well in the settings, the well will be exported without time to depth relationship. One or several wells can be exchanged by using the field “Borehole(s)” of the data connector. Select the well to copy from the Petrel® project browser and click on the arrow on the right of the label “Borehole(s)”. Select another well from the Petrel® project browser and click on the same arrow to add a well in the same field.

In Petrel®, each well log is associated to a set of MD curve. In PaleoScan™, several well logs associated to different MD curves cannot be grouped into a same log set. After the exchange using the PaleoScan™ Data Connector, the well logs will be re-organized according to the MD curves: All the logs associated to the same MD curve will be grouped into a same Log Set. The seismic log type is also imported during the exchange. Moreover, only the continuous well logs will be copied into the PaleoScan™ project unlike the discrete well logs. The PaleoScan™ Data Connector tries to respect the Petrel®

borehole hierarchy by using

folder name in PaleoScan™ log set.



of 30

In PaleoScan™, the CRS associated to the transferred well data will be the Petrel® project CRS.

Well Tops

The Well Tops can be integrated into the data connector in the same way as the borehole collection. Select the “Well Tops” folder from the Petrel® project browser and click on the arrow. Only the well tops associated to the wells available in the PaleoScan™ project will be exported, meaning no well tops will be exported if no wells are stored in the PaleoScan™ project. Well Tops can also be selected individually from the Petrel® database.

PaleoScan™ enforces the well tops CRS to be the same as the associated well. Moreover, well tops can only be transferred if the corresponding well is already created/imported into PaleoScan™. Therefore, the well tops CRS coming from Petrel® will not be transferred and the PaleoScan™ well CRS will be assigned to well tops.



of 30

F. Wavelets Wavelets can be exported from Petrel®. Select the wavelet(s) from the Petrel® project browser and click on the arrow associated to the Wavelet(s) field to add wavelet data in the plug-in.

G. Culture Data Objects defined with a Line/Polygons type can be transferred as culture data into PaleoScan™. One or several objects are exported by using the field “Culture Data” of the data connector. Select the object from the Petrel® project browser and click on the arrow on the right of the label “Culture Data”. Select another object from the Petrel® project browser and click on the same arrow to add another culture in the same field. All the objects listed in the field “Culture Data” will be copied into PaleoScan™ as several independent culture objects.

Only the X and Y values are exported to PaleoScan™. The Z data is not taken into account since the culture data have no vertical dimension in PaleoScan™. In PaleoScan™, the CRS associated to the transferred cultural will be the Petrel® project CRS.

H. Color Tables Color tables can be exported from Petrel®. Select the color tables from the Petrel® Templates window and click on the arrow associated to the Color Table(s) field to exchange the color bar between Petrel® and PaleoScan™



of 30

I. 2D Lines Seismic 2D Lines or General Intersection can be transferred from Petrel® as 2D lines into PaleoScan™. Select the Inline(s) and/or Xlines and/or Seismic 2D Line(s) from the Petrel® project browser and click on the arrow associated to the 2D Line(s) field.

The Seismic 2D Lines can be exported by selecting a 2D Survey from the Petrel® project browser. All the 2D Lines inside this survey will be copied into the PaleoScan™ project. Select the survey from the Petrel® project browser and click on the arrow to the right of the label “2D Seismic Survey”. If the given survey contains other surveys, the PaleoScan™ Data Connector will perform a recursive search to find all the contained 2D Lines and export them.

In PaleoScan™, the CRS associated to the transferred 2D Line will be the Petrel® project CRS.



of 30

J. 3D Objects Triangle meshes objects can be transferred from Petrel® as geobody(ies) into PaleoScan™. Select the triangle meshes objects from the Petrel® project browser and click on the arrow associated to the 3D Object(s) field to add triangle meshes data to the plug-in interface. You can also bring an entire folder of 3D objects by selecting the folder from Petrel® to the Folder field.

In PaleoScan™, the CRS associated to the transferred 3D objects will be the Petrel® project CRS.

K. Prefix for PaleoScan Export Before launching the data exchange, a prefix can be specified. It will be applied to the volumes, horizons, surfaces, faults, wavelets and culture data. This prefix can be changed by filling the field “Export prefix”.

Once all the fields are filled, click on the button “Run” to launch the data export from the Petrel® project to the PaleoScan™ project. A message is displayed when the copy is completed. The PaleoScan™ project browser is automatically updated.
