Caesar Prospect, SAAM and the March Towards Geophysical Excellence

Mike Cornyn, Stone Energy

Abstract Summary

The concept of geophysical excellence is an evolving goal. When this goal is reached, in theory, all geophysical aspects of an oil and gas prospect should have been evaluated and understood, and similar evaluations would also have been given to all other projects in a company’s exploration and development portfolio. All of this is done so that a proper risk assessment can assigned to each project so that a company can make money and grow.

One of the latest tools which could lead to geophysical excellence is called Seismic Amplitude Analysis Module (SAAM). This software is the output of the DHI Consortium, which is associated with Rose and Associates. It provides a set of questions, a risked past project results database, and interpretation definition and examples, which is designed to lead the geophysicist to examine and properly assess all seismic aspects of a prospect. This talk is going to use SAAM to examine a set of Pliocene amplitude events on the Gulf of Mexico Shelf. The prospect is a fault bisected, high rise three way fault trap in South Timbalier. The audience will be asked several of the SAAM questions to risk the prospectivity of these three amplitude anomalies. The results of the project drilling program will then be given.
