  	Citation × Citation Citation Abstract Copy Title: Drilling fluid/formation interaction at simulated in situ geothermal conditions. Final report Author: Enniss, D.O Year: 1980 Interaction of drilling fluids with a geothermal reservoir formation can result in significant permeability impairment and therefore reduced well productivity. This interaction is studied under simulated in situ geothermal conditions of overburden stress, pore fluid pressure, temperature, and pore fluid chemistry. Permeability impairment of an East Mesa KGRA reservoir material is evaluated as a function of stagnation time, drilling fluid, and temperature. Results indicate that all of these parameters contribute significantly to the magnitude and the reversibility of the impairment.

  	Citation × Citation Citation Abstract Copy Title: Control of Hydrogen Sulfide Emission from Geothermal Power Plants, Annual Status Report, June 1, 1975 - May 31, 1976 Author: Harvey, W.W. Year: 1976 A process for controlling H/sub 2/S emissions at geothermal power plants was evaluated in laboratory scale equipment and by process engineering analysis. The process is based on scrubbing geothermal steam with a metal salt solution to selectively remove and precipitate the contained H/sub 2/S. The metal sulfide is roasted or oxygen/acid leached to regenerate the metal salt, and sulfur is rejected from the system as elemental sulfur or as sulfate. Up to 95 percent removal of H/sub 2/S from simulated geothermal steams was obtained in a 2'' diameter scrubbing column packed with 3 feet of 5/8'' Flexirings by use of a recirculating slurry of copper sulfate/copper sulfide. Information is included on the chemistry, thermodynamics, kinetics and process control aspects of the process, scrubber system design, operation, and corrosion, and design proposals and cost estimates for a H/sub 2/S removal system.
