Title: Evaluating the Pot
ential to Generate Geothermal Electricity from Oil and Gas Wells

Geothermal Power uses the heat of the earth to generate electricity . In areas of very hot underground bodies, injected water is flashed to ste am producing electrical power, but in lower temperature areas, binary power plants can produce electrical power. Geothermal Power is 24 hours a day, 7 days a week, and 360 days a year. This is known as baseload power as oppo sed to solar and wind which are intermittent generators. There are no fuel costs since the plants use the earth’s heat. At reservoir temperatures abo ve 300⁰F, binary plants can generate electricity. Generally, these plants c ycle a fluid, generally water, to drive the binary electrical plant. “The amount of electricity generated is governed by the temperature of the circ ulating fluid and the volume of fluid cycled.” The oil and gas industry ha s developed extensive underground temperature data. Using oil and gas wells in high heat areas, especially horizontal wells, significant electrical po wer could be generated. A closed cycle would be created by joining horizont al or vertical wells downhole. Existing EOR techniques would form the basis of cycling. In high heat areas, redesigning new drill wells allows for hi gher flow rates generating greater amounts of electricity. The problem wit h geothermal power plants is their high cost, generally $3,000,000/MW. If a portion of the hydrocarbon cash flow is diverted to pay for the geothermal plant, then a long-lasting cash flow will outlive the depletion of the hyd rocarbons. There are now significant credits both tax and carbon that are a lso generated.
Mr. Bedford is the CEO of Mantle Power Co., LLC and is working on enhancing oil and gas production while linking in geothermal electrical pr oduction. Previously, he has been a consultant specializing in Basin Analys is and Enhanced Oil Recovery. His experience includes working for OOGC (CNO OC) as Rocky Mountain manager and Senior Eagleford geologic advisor. Prior he worked for Chesapeake as a senior East Texas geologist then moving into New Ventures as a Basin Analyst for the Haynesville, Bossier, Eagleford, Ma rcellus, Rhinestreet, and Bakken hybrid shale plays and the conventional Mi ssissippian play in the Midland Basin. Concurrently, he was geologic lead f or 27 Permian waterfloods. His experience includes geology, geophysics, gra vity magnetics, and oil migration.
