Summary

Description

A geographic information system focusing on Tertiary strata and Cretaceous-Tertiary coalbed gas was developed for the U.S. Geological Survey's (USGS) 2007 assessment of undiscovered, technically recoverable oil and natural gas resources of the Gulf Coast Region. The USGS Energy Resources Science Center has developed map and metadata services to deliver the 2007 assessment results GIS data and services online. The Gulf Coast assessment is based on geologic elements of a total petroleum system (TPS) as described in Dubiel and others (2007) and Warwick and others (2007). The estimates of undiscovered conventional oil and gas resources are within 33 assessment units (AUs) and the estimates of continuous coalbed gas resources are within 4 AUs. The hydrocarbon assessment units include the assessment results as attributes within the AU polygon feature class (in geodatabase and shapefile format). Quarter-mile cells of the land surface that include single or multiple wells were created by the USGS to illustrate the degree of exploration and the type and distribution of production for each assessment unit. Other data that are available in the map documents and services include the TPS and USGS province boundaries, as well as Claiborne Group structure and isopach maps.
