Progress in technology transfer and R and D of geothermal direct uses in three areas, by the Geo-Heat Center, are reviewed in this report. First, technical assistance was provided to 81 projects covering the entire development process from resource information to troubleshooting problems after a project has been completed. Second, applied research was conducted on: the performance of materials and equipment used in 13 geothermal district heating systems, wellbore/aquifer interaction and worldwide utilization of downhole heat exchangers, development of a US direct-use site data base, and development of information on transmission/distribution piping and analysis of uninsulated pipe for geothermal district heating systems. Third, an overview is presented on a technology transfer program which included: publishing a Guidebook, topical papers, and quarterly Bulletin, advising and referrals on projects, presentation and tours, geothermal library, and reporting activities to the Geothermal Progress Monitor. Papers on applied research projects have been processed separately for inclusion on the data base.

Reverse Combustion (RC) enhances coal seam permeability prior to Underground Coal Gasification. Understanding RC is necessary to improve its reliability and economics. A curved RC front propagation model is developed, then solved by high activation energy asymptotics. It explicitly incorporates extinction (stoichiometric and thermal) and tangential heat transport (THT) (convection and conduction). THT arises from variation in combustion front temperature caused by tangential variation in the oxidant gas flux to the channel surface. Front temperature depends only weakly on THT; front velocity is strongly affected, with heat loss slowing propagation. The front propagation speed displays a maximum with respect to gas flux. Combustion promoters speed front propagation; inhibitors slow front propagation. The propagation model is incorporated into 2-D simulations of RC channel evolution utilizing the boundary element method with cubic hermetian elements to solve the flow from gas injection wells through the coal to the convoluted, temporally evolving, channel surface, and through the channel to a gas production well. RC channel propagation is studied using 17 cm diameter subbituminous horizontally drilled coal cores. Sixteen experiments at pressures between 2000 and 3600 kPa, injected gas oxygen contents between 21% and 75%, and flows between 1 and 4 standard liters per minute …

This report is part of an ongoing series of quarterly publications that monitors discoveries of oil and natural gas in foreign countries and provides an analysis of the reserve additions that result. The report is prepared by the Energy Information Administration (EIA) of the US Department of Energy (DOE) under the Foreign Energy Supply Assessment Program (FESAP). It presents a summary of discoveries and reserve additions that result from recent international exploration and development activities. It is intended for use by petroleum industry analysts, various government agencies, and political leaders in the development, implementation, and evaluation of energy plans, policy, and legislation. 25 refs., 8 figs., 4 tabs.
