I. How does PaleoScan™ handle units?

PaleoScan™ can deal with different types of units (foot, meter, mile, yard, inch). For the wells, all the data are converted in meters into the application.

II. Can we define/modify the Coordinate Reference System?

The CRS of a project can be defined upon creation and can be modified later on. 

FAQ_3-a.png
The CRS of each object (seismic volumes, horizons, wells…) can be specified upon import and can be modified later on in the Unit/CRS Editor.

III. PaleoScan™ cannot launch any computation due to a lack of space on the temp file, what can I do?

When PaleoScan™ creates volumes, they are first generated at the location of the temporary file. If there is a lack of disk space, the user can change the location of the temp file via “Tools/Settings/Optimizations”.

VI. How can I synchronize colour bars and viewers?

To synchronize colour bars, the user has to click on the viewer which has the colour bar he wants to use, then keep holding down the ALT keyboard and drag and drop the colour bar into the other viewer.
To synchronize viewers, the user has to keep holding down the ALT key and drag and drop one viewer onto another one. To desynchronize viewers, the user has to keep holding down the ALT keyboard and drag and drop one viewer onto itself.

VII.Can I reduce the size of my project?

To reduce the size of a project, the user can use tge Data management tool available from the general toolbar.

The Data Management tool is a table which quickly summarizes the X-line and Time Slice volumes and their sizes. The total size of the project is displayed at the bottom left corner of the window.

The volumes that have not been computed are in red. The already computed volumes are in green. The user has to check or uncheck the boxes to either compute or delete the associated volume. Finally, they can click on Run to launch the computations. Note that it is impossible to delete the Inline volume via this interface because all the other volumes (X-Line and Time Slice) are computed from the Inline one.

In the Project Data Exchange window, the current project is displayed on the left-hand side of the window, whereas the remote project is on the right-hand side. To display the remote project, the user has to select it from the pull-down menu. If the project is not listed, they can search for it using the Scan Projects button.Data can be transferred between the current project and a remote project. For the transfer of volumes, the user can check the Crossline and/or Time-Slice options to associate the X-line and Time-slide volumes in the copy. Items can be deleted from the project browser by using the Delete option (Red Cross).To transfer items, the user needs to select them and click on the arrows in the middle of the Project Data Exchange tool. When the process is over, a message is displayed at the bottom of the interface. Several items can be selected and sent to the other project simultaneously.

Remote Links:

A remote link corresponds to a symbolic link to objects (Volumes and Horizon Stacks) contained in another reference project. It is commonly referred to as “shortcuts” or “linked files”.

This kind of link is a faster way to exchange data between projects and can be used to launch local computations. Moreover, it allows reducing the size of the working project.

A remote link can be created from the data exchange tool. The option Volume Copy Mode has to be unchecked (default mode). Once the remote link is generated, the remote object is displayed in the project browser of the working project with a specific icon:  

FAQ_9-c.png

To physically copy a volume, the user has to check the option Volume Copy Mode in the bottom left corner of the Project Data Exchange tool.

IX.What objects of my PaleoScan projects do I need to back up?

FAQ_9-e.png

X. How can I change the style of my objects (faults, geobodies, cultures, wells, markers etc.…)?

To change the style of an object, the user has to be in selection mouse mode (F shortcut), then double click on the object to select it and then change the style of the object through the properties panel.

XI.How can I display an object in a 2D viewer?

To display an object (faults, wells, markers, geobodies etc.…), this object has to be opened in the 3D viewer. Right click on the object in the Project Browser and choose “Open in 3D". The user can also drag and drop the object into the viewer or double click on it.

XII. How can I superimpose two different volumes on a 2D viewer?

To do so, the user has to open a blending viewer and then drag and drop each volume. The transparency can be adjusted by moving the cursor up and down. This type of display is also available for arbitrary lines, horizons and horizon stacks.

XIII. How can I reorganize my windows?

The following shortcuts can be used:

  • Shift+C: close all the window;
  • Shift+T: tile all the windows;
  • Shift+H: horizontally tile all the windows;
  • Shift+V: vertically tile all the windows;
  • Shift+M: minimize a window;
  • Shift+N: restore the window’s normal size.

     

XIV. Does PaleoScan™ automatically save my projects and objects?

PaleoScan will automatically save all the imported data and all the calculated volumes.

All the objects created in PaleoScan need to be saved manually by the user

The Model-Grids need to be saved using the Model-Grid toolbar save button. An emergency save is also automatically created every 100 propagations.

FAQ_11.png

Faults need to be saved using the Fault tool bar save button. An emergency save is automatically created every 10 fault validations. The saving frequency can be modified from the settings.

FAQ_12.png

Manually picked geobodies have to be saved individually. Multi-Z also need to be saved manually.

XV. How can I display both IL, XL and TS sections on a 3D viewer?

The user needs to drag and drop the seismic volume 3 times inside the 3D viewer, then select each section, using the selection mouse mode, (F shortcut) and change the Inline tab of the Volume Manager to Xline and Time Slice.
 

XVI. How can I create polygons?

On a Time Slice, Horizon Stack or horizon viewer, the user can pick a polyline using one of the polyline mouse modes available from the main toolbar.

FAQ_13.png
They can then select the polyline, using the selection mouse mode (F shortcut) and save it (CTRL+S) as a Polyline, 3D Polyline or Culture. It will be stored under the Polyline tab of the Project Browser.A Polyline is never displayed in the 3D viewer and is mapped on the selected Horizon Viewer or on the displayed horizon of a selected Horizon Stack viewer. This behaviour enables the geobody extraction.A 3D polyline is displayed in the 3D viewer but not on 2D viewers.A Culture is displayed at Z=0 in the 3D viewer and is snapped to every Time Slice and Horizon Slice in 2D view.

XVII. How can I apply and save a stretch/rotation to my section? How can I apply it to other viewers?

The user can use the buttons from the top toolbar to flip, rotate or stretch the displayed seismic section. The rotation and stretching can then be saved using the top toolbar or by right clicking on the top bar of the viewer. 

FAQ_14.png
FAQ_15.png

To apply the same rotation and stretch to other seismic viewers, the user can first apply the rotation and stretch to a specific viewer. Then, they can open all the other viewers and synchronize them together by holding down the ALT keyboard button and drag and dropping the first viewer into the other ones. Once all the viewers are linked, the user can zoom in/out in the first rotated and stretched viewer, all the other viewers will be updated.

XVIII. How can I flatten a seismic section along a specific horizon?

From the 2D viewer, the user has to click on the Horizon Flattening option available at the bottom left corner of the window. To flatten along a horizon from the database, they need to drag and drop the horizon from the Project Browser into the Horizon drop zone and then click on OK. To flatten according to a horizon viewer, they have to click on Viewer as an input and then select the horizon viewer on which to flatten from the pull-down menu.

The flattening can be disabled or activated at any moment thanks to the OFF/ON buttons.
