RM-6 — Structure of the Permian Guadalupian Capitan Aquifer, Southeast New Mexico and West Texas

W. L. Hiss, 1976, Scale 1:500,000.

The Capitan aquifer of Permian (Guadalupian) age is an important source of the ground water used for municipal, industrial, and agricultural purposes at and in the vicinity of Carlsbad, N. Mex. In addition, water pumped from this aquifer in southern Lea County, New Mexico, and Winkle r and Ward Counties, Texas, is injected into other subsurface reservoirs by oil companies to increase the recovery of petroleum from partly depleted oil fields (Hiss, 1971; White, 1971). A knowledge of the structural position of the Capitan aquifer in southeastern New Mexico and western Texas will be useful in programs designed either to explore for and develop additional ground-water supplies or to manaage this important resource.
