Abstract

There are several abandoned and low-production gas wells in the Haynesville and Eagle Ford shale formations that are no longer monetized. The scope of this study is to assess the potential for repurposing multiple transverse fracture horizontal wells (MTFHWs) in these formations as low-grade enhanced /engineered geothermal systems (EGS).

This envisioned approach used Drillinginfo and other available data to categorize existing gas wells as active, depleted, and still on production or abandoned. Once the categorization was made, machine learning model was implemented to quantify the current and near-future EGS potential of these wells. Finally, results from the preceding study were used to evaluate how best to distribute power plants for effective use and estimated that 20MW power generation was possible for 20 years.

The result of this research is a forecast of low grade EGS power generation potential reserves in the Eagle Ford and Haynesville shale gas formations. This forecast addressed both technical and economic aspects. In fact, this work provides a methodology for assessing the resource potential of EGS from existing MTFHWs in formations having sufficiently high temperature for low-grade geothermal heat extraction.

This research provides input to support potential EGS development in Texas that could supply clean, affordable, and continuous (unfluctuating) power for small municipalities or industrial applications or could contributes to the regional grid power supply.
