Abstract

The Bureau of Economic Geology's Offshore Secondary Gas Recovery program is a multi-fiscal year project funded by the U.S. Department of Energy, whose goals are to research new techniques and methods in defining the structure, stratigraphy, and hydrocarbon character in a mature area in the northern Gulf of Mexico and to utilize those multidisciplinary techniques and methods to identify additional gas resources, as well as predict regional trends in hydrocarbon accumulation. PHASES 1 and 2 of the project work plan (PROJECT PREPARATION and DATA GATHERING AND LOADING, respectively) have been completed. PHASE 3 of the plan (DATA ANALYSIS) is ongoing. All key chronostratigraphic surfaces have been mapped in logs, cross sections have been generated, and total thickness and is lith maps have been completed for all systems tracts in the reservoir units within the study area. Targets for resource additions have been identified and classed into target types, and preliminary resources have been calculated for these targets. Root-mean-squared amplitude maps have been used to better define opportunities within the internal architecture of larger stratigraphic features. Seven play types recognized within the study area have had their architecture and anatomy detailed. Previous work in the Offshore Gulf of Mexico (Hentz and others, 1997; Seni and others, 1997) defines the regional distribution of these same plays.
