Plugging procedures and suspension of drilling operations for injection well KS-7

Abstract

"During the drilling of injection well KS-7, the Puna Geothermal Venture has encountered a high temperature, high pressure zone at depth of 1600'. This zone caused the fluid and steam release on the afternoon of February 21, 1991. Since that time the well has been shut in and is being kept in a stable condition by continuous pumping of cold water into the well bore. During this period equipment and personnel were assembled in order to plug the well. PGV is hereby requesting authorization to execute plugging and monitoring operations that we feel are required to bring the well to a stable and safe condition for the long term. This program is described in the attached document and figures."
