Thermometry in geothermal wells: an optical approach

Applied Optics, 1985
A temperature measuring system based on purely optical devices is described, which exploits the temperature dependence of the physical properties of a birefringent crystal. The system is expected to measure the temperature profile in geothermal wells up to 500° C and with a resolution better than 0.1 ° C.

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.

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.

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.

Geothermal Drilling and Well Design

2013
This chapter begins by describing the construction of geothermal wells. The drilling process and equipment follow, but this is under continuous development, and the techniques described have been chosen to illustrate the issues rather than the latest practice.
