Analyzing Wellbore Trajectories

Trajectory View displays the wellbore including a gamma ray digital curve, casing pipe segments, perfs and Frac objects, Frac program results, and formation tops.

The Trajectory View tab shares some of the existing Profile Viewer functionality available in other tabs and in the pane to the right of the display pane. For example, you can add or edit downhole completions using the Profile Viewer Completions tab, which automatically appears in the Trajectory View tab. Likewise, you can change log definitions for the gamma ray curve using the Digital Logs pane to the right of the display pane, and increase the Viewport setting to accentuate subtleties of the wellbore trajectory.

Casing segments are broken into virtual segments that may not duplicate the actual casing pipe segmentation. Virtual casing segments are generated using a methodology based on casing interval, casing diameter, and directional survey.

To analyze wellbore trajectories

With the Profile Viewer dialog box displayed, click the Trajectory View tab in the bottom left of the Profile Viewer dialog box.

The wellbore appears in the Trajectory View tab display pane.

Roll the mouse wheel to zoom in to a portion of the wellbore that's of interest, and then click that point to define it as the center of rotation.

The point clicked is centered in the display pane, and the North and South markers move alongside it.

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.

Using the Profile Viewer Frac tab, display one of several graph types in the vacant track in the wellbore. Further specify whether each Frac treatment appears as either a Bar graph at the specific location along the wellbore where it occurred, or as an Area graph that runs continuously from the start of the shallowest Frac treatment to the end of the deepest.

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.
