Abstract: An Integrated Approach Using GIS for Evaluating Exploration and Production Potential in the Gulf of Mexico

Geographic Information Systems (GIS) provide a powerful tool for compiling and analyzing varied data types in exploration and production settings. GIS data layers that can be combined for the Gulf of Mexico region include: 1) lease owner and operator information; 2) well location data; 3 availability of paleontological data, velocity check shots, and digital well logs; 4) surface geology; 5) distribution of faults and salt bodies; 6) field and play outlines; 7) reservoir and production information; 8) topography, bathymetry, and bathymetric images; and 9) locations of key published crosssections, seismic lines, and field studies. GIS maps can be easily redisplayed at any scale and with different projections. In this poster session, we show examples of how various GIS data types can be combined on maps to illustrate: (1) the amount and type of existing geologic work in a new area; (2) the relationship between prospective areas and identified plays, existing fields, and wells; (3) the proportion of oil and gas production by age of the reservoir for production fields with multiple pay zones; or (4) the spatial distribution of current lease ownership and lease expirations.

Thus, GIS databases like that described for the Gulf of Mexico are an invaluable resource and will become a standard tool utilized by teams searching for new reserves in underexplored as well as mature basins.
