Review of the Drilling R and D Program at Sandia
Drilling projects conducted for the Division of Geothermal Energy (DGE) and the Office of Energy Research (OER), both of the Department of Energy (DOE), are described. The DGE Well Technology Program includes drilling, well completion, and high temperature logging instrumentation R and D for geothermal applications. Accomplishments to date include successful laboratory testing of the continuous chain drill and development of temperature, pressure, and flow sondes capable of operation at 275/sup 0/C. Efforts are also under way to develop high-temperature, high-performance bits, high-temperature drilling fluids, and high-temperature downhole motors. Bearings, seals, and lubricants for use in high-temperature bits and motors are also being developed and tested. Recent results are presented. An OER drilling experiment into a lava lake at Kilauea Iki, Hawaii, is being conducted. Materials and techniques for drilling into an active magma/hydrothermal system are in a preliminary phase of study.
