Pick Lithology Intervals

RockWorks: Pick Lithology Intervals

RockWorks | Borehole Operations | Striplogs | Lithology Picker

Use this program to interactively select the depths to the top and base of lithology intervals, from logs displayed in cross section, typically displaying geophysical data or raster images. Simply display the sequence of logs, and then point-and-click to pick the lithologic intervals. The depths are recorded in the project’s Lithology table.

! This tool will assign depths assuming vertical boreholes. If your boreholes are deviated, you may need to eventually edit by hand the picked formation depths, based on how the log intervals look when displayed in diagrams that can accommodate the borehole’s deviated downhole trace.

You can display an unlimited number of boreholes in the lithology picker display (the equal-spacing option makes it easy to view many at once), though screen real estate may still be a limitation. You can add new lithology material types on the fly within the lithology picker.

See Picking Stratigraphic Contacts for a similar tool for picking ordered formations (Stratigraphy data) from logs.

Step-by-Step Summary

Because the lithology picker displays known data in two or more vertical striplogs, these options will look just like the 2D Section diagrams in the Striplogs menu. Be sure to follow very carefully the steps listed in the Step-by-Step section below.
