Description

Geothermal is ‘hot’ right now. There has been a significant increase in the exploration and pilot demonstrations of geothermal energy beyond traditional district heating due to new-edge drilling and completion, such as single/multi-well closed-loop and horizontal well drilling and stimulation of “hot dry rock” (HDR).

We conduct a thorough, multi-scale characterization of geothermal resources in Presidio County of the Trans-Pecos region of Texas and assess techno-economics for power generation and direct use facilities. We analyze and integrate outcrops and subsurface geologic, geophysical, and thermal data for resource characterization and quantification. Presidio County has substantial, undeveloped geothermal resources. The workflow establishes a standard for subsurface characterization and techno-economic scenario analysis for enhanced geothermal and closed-loop systems for power generation and direct use.
