Log Correlation Module

The Log Correlation Tool is used to correlate formation tops, unassigned tops/faults, and pay intervals. This tool can display both raster and digital logs. For a more comprehensive set of options, the Cross Section Module provides more advanced options beyond top picking. As another alternative, the Slip Log Module displays and pick tops on up to four horizontal raster logs.

To open the Log Correlation Tool:

Main module: Tools>Log Correlation
Click the Log Correlation button on the Main module toolbar

Getting Started

The guide at the top of the screen shows the suggested workflow for using the Log Correlation Tool. You'll want to select a few wells, set the Log Types for each track, put raster logs inside those Log Types, set the depths, and finally select and pick tops and pay intervals. The Quick Guide on the top of the screen has a set of buttons that link directly to these tasks.
