9 Hydrocarbon Production:

The Tertiary deposits of the Texas Gulf Coast, including the Texas City area, have been extensively drilled for gas and oil. Several published atlases summarize oil and gas drilling and production activity along the Texas Gulf Coast, including those of Galloway and others (1983) and Kosters and others (1989). Principal petroleum targets in the Texas City area are within the Frio Formation, although there is production from the Oakville Formation as well. The oil- and gas-field maps of Galloway and others (1983) and Kosters and others (1989) were used in the GIS because they provide a summary of where oil and gas wells are concentrated. Because of the large number of wells in the Texas City area that penetrate the Lagarto/Oakville interval, locations of all existing and plugged wells should be considered when determining the location of CO2 sequestration wells. Proprietary maps compiled by Geomap (http://geomap.com) provide more detailed information regarding well and field locations in the Texas City area.
