Abstract

Finding drinking-water reservoirs, mainly located between depths of 800 m to 2000 m, is important in reducing the current deficit supply of drinking water to Mexico City. The acquisition of reflection seismic, the reprocessing of old 2D lines, the reprocessing of well-log data, and the use of gravity data allowed the creation of an earth model of the studied area, consistent with all available geophysical and geologic information, and defined 10 drilling prospects. In addition, based on data-integration results, a deep regional fault named Texcoco-Iztapalapa fault was identified. The seismic-reflection method, combined with interpretation techniques developed and commonly used for oil and gas exploration, can be adapted to drinking-water prospecting.
