Three-Dimensional Hydrogeologic Framework of Aquifer Units in the Delaware Basin, Southeastern New Mexico - Open-file Report - 623

The project described here is for the Delaware basin of southeastern New Mexico, where shallow groundwater aquifers overlie some of the world’s most prolific oil and gas reservoirs. The New Mexico Energy, Minerals and Natural Resources Department Oil Conservation Division funded this project to better protect and manage water resources in this part of the state, facilitate the well drilling permit process, and make spill response quicker and more informed. The Guadalupe Mountains are a significant recharge area for groundwater resources in the Carlsbad area and the southernmost reach of the Pecos River in New Mexico. Oil and gas production and associated saltwater injection activities are strikingly conspicuous throughout the project area, and underground mines southeast of Carlsbad are an essential source of the nation’s potash supply. Additionally, the Waste Isolation Pilot Plant’s radioactive waste repository is located in the north-central portion of the study area. The amount and variety of subsurface activity highlight the need for digital 3D hydrogeologic data suitable for efforts to manage subsurface resources in this region.
