Book excerpt: A tracer test was carried out in a geothermal doublet system to study the injection behavior of a developed reservoir known to be fractured. The doublet produces about 320 gpm of 160 F water that is used for space heating and then injected; the wells are spaced 250 ft apart. Tracer breakthrough was observed in 2 hours and 45 minutes in the production well, indicating fracture flow. However, the tracer concentrations were low and indicated porous media flow; the tracers mixed with a reservoir volume much larger than a fracture.

Available in PDF, EPUB and Kindle. Book excerpt: Two tracer tests on doublet systems in a fractured geothermal system were carried out in Klamath Falls, Oregon. The purpose of the tests were to obtain data which would lead to information about the reservoir and to test the applicability of current tracer flow models. The results show rapid breakthrough times and indicate fracture flow with vigorous mixing of injector fluid before production of same. This leads to the idea that thermal breakthrough is not directly related to tracer breakthrough in the Klamath Union doublet system. There has been no long-term enthalpy loss from exploiting the resource for 40 years. In order to reduce the data, models were developed to analyze the results. Along with a porous media flow model two mathematical models developed to analyze fractured geothermal systems are used to help decipher the various tracer return curves. The flow of tracers in doublet systems was investigated. A mathematical description is used for tracer flow through fractures as a function of time and various nonlinear parameters which can be found using a curve fitting technique. This allows the reservoir to be qualitatively defined. These models fit the data well, but point to the fact that future improvement needs to be considered for a clearer and more quantitative understanding of fractured geothermal systems. 22 refs., 32 figs., 11 tabs.
Book Synopsis Geothermal Energy in Europe by : J. C. Bresee
Download or read book Geothermal Energy in Europe written by J. C. Bresee and published by CRC Press. This book was released on 1992 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report of a research project in eastern France, a pilot study for a much larger effort to determine whether geothermal energy resources can be developed in areas without natural geothermal reservoirs, which includes a good deal of industrial northern Europe. The idea is to drill a hole deep enough to hit hot rock, then circulate high-pressure water between the hot rock and heat exchangers at the surface; it was developed at Los Alamos National Laboratories. Includes a half-page subject index. Annotation copyright by Book News, Inc., Portland, OR

Book excerpt: The chemicals under consideration for tracing in the Klamath Falls geothermal reservoir are Potassium-iodide, Rhodamine WT and Fluorescein. The latter two belong to a group of organic chemicals known as xanthene dyes. The advantages of using Fluorescein and Rhodamine WT are that fluorometry can be used to measure concentrations, the equipment used is relatively inexpensive, the process is straight forward and simple, and the minimum detectability is in the ppm to ppb range. The health hazard of both dyes are minimal at worst; they have been used to trace blood flow in living animals. Potassium-iodide is an inorganic chemical which is soluble in cold water (127.5 g/l00cc). When used as a tracer the iodide is detected using a specific ion electrode the detect ability is in the ppm range. Since the concentration of iodide in ground water is extremely low iodide is prefered over other halides (chloride, bromide). The advantages of using potassium-iodide for a fluid tracer is that like the fluorescent dyes the method is simple and no expensive highly elaborate systems are needed for quantitative measurement. Also, potassium-iodide is non-toxic, thus posing no health hazard if the test aquifer mixes with a drinking water supply.
