This book was released on 1984 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The rates of most chemical reactions are very sensitive to temperature, and this property can be used to measure temperature patterns in geothermal reservoirs. Two approaches are considered: reverse-flush and flow-through. Both of these can indicate thermal drawdown faster than the measurement of produced-fluid temperature. The reverse-flush approach is more difficult to carry out and interferes more with normal operation, but it gives the earlier indication of thermal drawdown and yields more information when using a single reaction. In both approaches, injecting a suite of reactants can yield bivariate time-temperature distributions which give temperature distributions as functions of fluid residence time. Applications to Hot Dry Rock systems are considered throughout the paper. Results of early kinetics studies of candidate tracer reactions also are reported.

Available in PDF, EPUB and Kindle. Book excerpt: Non-reactive tracer tests in prototype hot dry rock (HDR) geothermal reservoirs indicate multiple fracture flow paths that show increases in volume due to energy extraction. Tracer modal volumes correlate roughly with estimated reservoir heat-transfer capacity. Chemically reactive tracers are proposed which will map the rate of advance of the cooled region of an HDR reservoir, providing advanced warning of thermal drawdown. Critical parameters are examined using a simplified reservoir model for screening purposes. Hydrolysis reactions are a promising class of reactions for this purpose.
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 Synopsis Flow and Contaminant Transport in Fractured Rock by : Jacob Bear
Download or read book Flow and Contaminant Transport in Fractured Rock written by Jacob Bear and published by Academic Press. This book was released on 2012-12-02 with total page 575 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past two or three decades, fractured rock domains have received increasing attention not only in reservoir engineering and hydrology, but also in connection with geological isolation of radioactive waste. Locations in both the saturated and unsaturated zones have been under consideration because such repositories are sources of heat and potential sources of groundwater contamination. Thus, in addition to the transport of mass of fluid phases in single and multiphase flow, the issues of heat transport and mass transport of components have to be addressed.
Book Synopsis Tracking Thermal Fronts with Temperature-sensitive, Chemically Reactive Tracers by :
Download or read book Tracking Thermal Fronts with Temperature-sensitive, Chemically Reactive Tracers written by and published by . This book was released on 1987 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Los Alamos is developing tracer techniques using reactive chemicals to track thermal fronts in fractured geothermal reservoirs. If a nonadsorbing tracer flowing from the injection to production well chemically reacts, its reaction rate will be a strong function of temperature. Thus the extent of chemical reaction will be greatest early in the lifetime of the system, and less as the thermal front progresses from the injection to production well. Early laboratory experiments identified tracers with chemical kinetics suitable for reservoirs in the temperature range of 75 to 100°C. Recent kinetics studies have focused on the kinetics of hydrolysis of derivatives of bromobenzene. This class of reactions can be used in reservoirs ranging in temperature from 150 to 275°C, which is of greater interest to the geothermal industry. Future studies will include laboratory adsorption experiments to identify possibly unwanted adsorption on granite, development of sensitive analytical techniques, and a field demonstration of the reactive tracer concept.

Book Synopsis Reservoir Modeling Using Chemically Reactive Tracers by :
Download or read book Reservoir Modeling Using Chemically Reactive Tracers written by and published by . This book was released on 1982 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: This memo lays out a theoretical basis for geothermal reservoir modeling using chemically reactive tracers. First, the concept of utilizing the temperature dependent kinetics of a chemical reaction to measure thermal drawdown is demonstrated using a simplified plug flow reservoir model. Then, an analysis of the transient behavior of a chemically reactive tracer experiment will show how these diagnostic tests may be used to determine a more reliable reservoir model than we are able to achieve with our current methods.
Book Synopsis Geothermal Reservoir Engineering by : E. Okandan
Download or read book Geothermal Reservoir Engineering written by E. Okandan and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the oil crisis of 1973, we suddenly became aware that fossil fuel resources are limited and will be exhausted soon if new alternatives are not put into use immediately. Conservation measures and extensive research on new sources of energy has eased the demand on fossil fuels, especially crude oil. Geothermal energy as an alternative; source had its share in this devel opment and electricity producing capacity increased from 700 to 4700 MWe during 1970 to 1985. Geothermal reservoir engineering emerged as an impor tant field in the assessment of geothermal sources. During the 25 years of its development, several areas were identified that needed further at tention for the correct description and interpretation of reservoir be havior. This fact as accepted by all operators is vital for the steady and continuous operation of power plants. During this NATO ASI, a detailed review of theory and field case his tories on geothermal reservoir engineering was presented. In understanding .the reservoir, conceptual models, natural state models, well bore measure ments, transient and tracer testing provide data which are indispensable. They are powerful tools in understanding reservoir behavior provided we know how to interpret them. During lectures the theory and practical applications of these interpretive methods were discussed.

Download or read book Inert and Reacting Tracers for Reservoir Sizing in Fractured, Hot Dry Rock Systems written by and published by . This book was released on 1986 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flow characterization and volumetric sizing techniques using tracers in fractured hot dry rock reservoirs are discussed. Statistical methods for analyzing the residence time distribution (RTD) are presented. Tracer modal volumes and RTD shape are correlated with reservoir performance parameters such as active heat transfer area and dispersion levels. Chemically reactive tracers are proposed for mapping advance rates of cooled regions in HDR reservoirs, providing early warning of thermal drawdown. Important reaction rate parameters are identified for screening potential tracers. Current laboratory research and field work is reviewed.
