Constructing Deep Closed-Loop Geothermal Wells for Globally Scalable Energy Production by Leveraging Oil and Gas ERD and HPHT Well Construction Expertise

, 2021
Deep closed-loop geothermal systems (DCLGS) are introduced as an alternative to traditional enhanced geothermal systems (EGS) for green energy production that is globally scalable and dispatchable.

Numerical study of the effects of CO2 gas in geothermal water on the fluid-flow characteristics in production wells

Engineering Applications of Computational Fluid Mechanics, 2021
In this study, we numerically investigated the effects of CO2 gas in geothermal water and the scale deposition formed in the wellbore on the flow characteristics.

Energy and Exergy Analysis of a New Power, Heating, Oxygen and Hydrogen Cogeneration Cycle Based on the Sabalan Geothermal Wells

International Journal of Engineering, 2019
In this paper, a new power, heating and hydrogen cogeneration cycle from Sabalan geothermal two wells is proposed and analyzed. In the proposed system, a new double flash cycle and organic Rankine cycle are used for power production.

WELL TESTING IN TWO-PHASE GEOTHERMAL WELLS

Proceedings of SPE Annual Fall Technical Conference and Exhibition, 1978
Abstract This paper deals with the possibility of using usual oil well transient pressure testing methods in hot water wells when flashing occurs in the wellbore. Multiple rate analysis techniques have been successfully applied to available data on a well drilled by B.R.G.M.

Cementing Geothermal Steam Wells

Journal of Petroleum Technology, 1964
Abstract Cementing deep, high-temperature oil wells where static temperatures range from 350 to 400F has become routine in the past decade. In the United States there were 271 wells drilled deeper than 15,000 ft during 1963. Many of these wells had static temperatures higher than 400F.

Completion of producing geothermal wells

Geothermics, 1970
Abstract Completion of producing geothermal wells involves a series of operations. Following a brief description of spontaneous blowout, different systems to start production of wells are discussed. Should blowout fail to occur spontaneously from the well, several techniques (plunger piston, gas-lift and foaming operations) are applied.

Geothermal Well Cementing Technology

Proceedings of Southeast Asia Show, 1984
ABSTRACT The success or failure of drilling and completing Geothermal Wells depends reatly on available cementing technology. This requires not only having the knowledge of temperature stable competent materials but also a complete understanding of hole preparation, casing running procedures, mud displacement, lost circulation and the ...
