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 ...

Cementing materials for geothermal wells

Geothermics, 1972
Abstract In a well used in the search for endogenous fluids the opportunity exists to stop level of thermal waters of high temperature and pressure so that deeper levels can be reached, where it is inferred that there are fluids with better thermodynamic characteristics.

Drilling mud in geothermal wells

Geothermics, 1970
Abstract Owing to high thermality in areas where harnessing of endogenous steam takes place, an accurate choice of the type of circulating mud proves necessary in order to maintain the drilling fluid properties when temperatures exceed 140 °C. Along with high temperature effects, an analysis is made of alterations of mud constituents because of the ...
