Abstract: Several Case Studies of Onshore 2-D Depth Migrations Completed on a Workstation

Barry L. Weinman

A 2-D pre-stack and post-stack depth migration study was performed on several lines in two different structural settings (Gulf Coast on-shore and the Mexia Talco fault trend in east Texas). The purpose of the study was to increase the accuracy of fault positioning and improve structural imaging below fault shadow zones.

The velocity field was initially determined by ray traced Previous HitcoherencyNext Hit Previous HitinversionNext Hit, improved by residual move-out analysis on depth gathers, and was completed by the application of global tomographic Previous HitinversionTop.

Evaluation of the results from the depth migration is completed by a comparison to well control.
