WELL LOG INTERPRETATION AND VISUALIZATION
The graphics in this section come from a project in my petroleum geology class. Students were required to examine 17 well logs and make picks based on gamma ray, resistivity, porosity, and density curves. Having made these picks, the assignment called for two deliverable: I) contour surfaces representing the contacts between the rock layers, and II) stratigraphic cross sections along the A-A' and B-B' lines.
​
These tasks were completed in Rockworks.
well logs rotation
This animation shows rotation of the well logs.
well and cross section map
This map shows the location of the wells, and lines corresponding to the plane of the required cross sections.
A- A' cross section
Rockworks interpolated the depths of the contacts along the selected cross section line.
B-B' cross section
Rockworks interpolated the depths of the contacts along the selected cross section line.

In this animation, the two cross sections have been merged into a fence diagram.

The second deliverable for this assignment required modeling the contact surfaces by interpolating between the known picks in the well logs.
well logs with picks
This graphic shows the geographic distribution of the wells. The lithology types were determined by manually examining the logs. The colors on the contact surfaces represent depth and not lithology type. The lithology types are color coded in the logs.
