Abstract : A series of horizontal drilling tests were conducted by the Naval Civil Engineering Laboratory (NCEL) at the Naval Weapons Center (NWC) China Lake, California, and at NCEL, Port Hueneme, California, under the sponsorship of the Space and Naval Warfare Systems Command (SPAWAR). The purpose of these tests was to demonstrate the operational capability of a horizontal drilling system (HDS) - a prototype system using high-pressure water as the drilling medium. Test results have provided preliminary confirmation of drill string steerability and drill string friction criteria under limited conditions. This report documents HDS FY91 tests at NWC China Lake and NCEL, and provides a discussion regarding test results.
