This ongoing laboratory-based high risk/high payoff R and D program has already yielded several durable cost-effective materials of construction for geothermal energy processes. In FY 1991, R and D in the following areas will be performed: (1) development and downhole testing of advanced high-temperature (300{degrees}C) CO{sub 2}-resistant lightweight (1.1 g/cc) well-cementing materials, (2) high-temperature chemical systems for lost-circulation control, (3) thermally conductive scale-resistant composites for heat-exchanger tubing, (4) high-temperature chemical coupling materials which can be used to bond elastomers to steel substrates, and (5) high-temperature elastomers for use in downhole drill motors. Contingent upon the results, work on heat-exchanger tubing and lost-circulation control materials will be completed FY 1991 and the other activities will be continued in FY 1992. Work on other materials needs will commence in FY 1992. These include the in situ conversion of drilling fluids into well-completion materials and ceramic-type well casing. All of the subtasks will be performed as cost-shared activities with other National Laboratories and/or industry. Successful developments will significantly reduce the cost of well drilling and completion, and energy-extraction processes. Results to date are discussed. 2 refs., 2 figs., 2 tabs.
