Abstract

On September 10, 1991, the Tonto drill rig resumed work on the HGP-A well for the Pacific International Center for High Technology Research (PICHTR) Downhole Coaxial Heat Exchanger (DCHE) project. This work included the retrieval of a bridge plug in the HGP-A well. Following the completion of the work at the HGP-A well on September 15, 1991, the Tonto rig was moved to the SOH-1 site for a clean out operation, which was completed on September 20, 1991. The Tonto rig was then demobilized and shipped back to the mainland.
