Viewing Cross Sections

Launch a cross section in Wellbore 3D Viewer. Only the wells included in the cross section appear in Wellbore 3D Viewer. A fence diagram is automatically created.

The digital gamma ray, which indicates the underlying geology is displayed where it is available from the S&P Global Inc. Information Hub. When it is not available, just the bore hole and tops are displayed.

Some of the options available for Wellbore 3D Viewer for single wells are not included when displaying a cross section.

To view cross sections in Wellbore 3D Viewer

Using the Cross Sections tab of the main toolbar, or the context menu while inspecting cross sections on the map, select Wellbore 3D Viewer ().

The Wellbore 3D Viewer dialog box appears.

Configure the Wellbore 3D Viewer viewport based on the following guidelines:

Viewport - type or select the start subsea depth at which the viewport begins. Using the Height box, type the depth to include in the viewport down to a minimum value of 25 m to accentuate subsurface trends. The amount you type extends down from the Start Subsea you specified. Visual objects (tops, annotations, etc.) that appear above the Start Subsea depth specified in the Viewport pane are truncated. This removes shallow objects so that you can focus on deeper zones.
Digital logs are truncated at nearly the exact depth specified based on the digitizing increment. Objects in deviated wellbores are truncated using the directional survey stations for precision. Vertical wellbores are truncated using a precision increment of 100 m.

Select from the following Render options:

Tops - whether names of formation tops appear in the main display pane. Subsea depths in user else system format are posted for all tops displayed in the wellbore. You can still select and apply formation tops in the Structural Surfaces pane regardless of whether this option is enabled. Where an unrealistic depth appears for a given formation, correct that instance of the formation depth using Profile Viewer, or AccuLogs, and then using the Wellbore 3D Viewer window, click Reload Data to update the display.
Annotations - whether annotations created using Profile Viewer appear in the main display pane. If subsequent changes are made to annotations while the Wellbore 3D Viewer remains open, click to display the latest changes in Wellbore 3D Viewer.
Land Grid - whether to display DLSS, FPS, and NTS grids for wells in BC, AB, SK, MB, and NWT. A structural surface must be displayed in the Wellbore 3D Viewer in order for the land grid to appear.

Using the Digital Logs group, select the coloring and cut off settings for the log, and surrounding logs (Other Wells), and whether a measured depth grid appears. When MD Grid is selected, the log scale --including the left and right scale, and curve mnemonic appear at the bottom hole location. If Other Well is selected, it appears at the bottom of all wells.

The gamma ray logs for relevant wells are only downloaded from S&P Global Inc. the first time they are displayed for a well. The log file is written to the \DigiGeoData\Wells\UWI\log folder that appears in your AccuMap data directory. The file is in compressed crv format and loaded from there in future sessions. Select Normalize GR to normalize the curve using overlying and underlying shales. To reduce clipping, select large value from the Max GR drop-down list.
Set the structural surface based on the following guidelines:

Structural Surfaces - the list of relevant tops is constructed using neighboring tops that fall within + or - 4,000 meters of the spatial center. Using the drop-down list, select the formation(s) to display and to compare against the subject wellbore. For horizontal wells, a proximity envelope is shaded to indicate the degree to which the horizontal well varies from true vertical depth and the amount by which it either falls short of or exceeds the depth of the formation selected. To shade individual proximity envelopes for every horizontal well in the viewport, click the Other Horizontal Wells check box.
Select <Surface> from the above options to show the stratigraphic surface.
Transparency Slider - Drag the slider to control the opacity of the formation selected in the formation drop-down list to the left. The right-most position is no opacity. The left-most position is maximum opacity. Enable the Dark Mode option that appears in the Settings group of the Main Ribbon to increase the contrast.
Data Points - Enable to display the data points upon which the rendering of a structural surface are based.
Click Save Settings as Preferences to save the above settings as the default display settings with which to render both the current well and future wells that have not been displayed before in the 3D Wellbore Viewer. Any alterations to the latest display are saved for that particular well and used the next time it is displayed in 3D Wellbore Viewer. These settings only override the last saved default preferences when you click Save Settings as Preferences.

Roll the mouse wheel to zoom in to an object or a portion of the layer cake that's of interest. Click that point to define it as the center of rotation, and then click and drag your mouse to rotate the wellbore in any direction.

A high-degree of rotation control is possible by zooming in significantly and then clicking a new point to define a more precise rotation center point each time that you adjust the wellbore angle of rotation.

Hover the cursor over attributes in the wellbore, such as the gamma ray curve, a casing pipeline segment, a Frac object or Frac graph, a perf treatment, or a formation top in order to display details in a tooltip window.

Click the Legend tab in the bottom-right of the Wellbore 3D Viewer dialog box to display a color chart correlated to completion types and to fluids.

Output the display pane by clicking either Print Preview or Copy... in the Main ribbon.

Not all printers support transparent mode and for those that do, processing can be extremely time-consuming. Because of this limitation, Wellbore 3D Viewer converts the semi-transparent structural surface to opaque during Print Preview mode. To preserve semi-transparent mode, click Copy as Bitmap () in the Main ribbon of the Wellbore 3D Viewer and then paste the image into a third-party application such as Microsoft Office and print it using that product.

Save your current Wellbore 3D Viewer settings (including viewport) as the default display settings with which to render both the current well and future wells that have not been displayed in the Wellbore 3D Viewer before. Any alterations you make to the latest display are saved for that particular well and used the next time that well is displayed in Wellbore 3D Viewer instead of the overall default settings. These modified settings only override the last saved default settings when you explicitly save them by clicking Save Settings as Preferences.
