Geothermal Reservoir Engineering Book Review:

Geothermal Reservoir Engineering offers a comprehensive account of geothermal reservoir engineering and a guide to the state-of-the-art technology, with emphasis on practicality. Topics covered include well completion and warm-up, flow testing, and field monitoring and management. A case study of a geothermal well in New Zealand is also presented. Comprised of 10 chapters, this book opens with an overview of geothermal reservoirs and the development of geothermal reservoir engineering as a discipline. The following chapters focus on conceptual models of geothermal fields; simple models that illustrate some of the processes taking place in geothermal reservoirs under exploitation; measurements in a well from spudding-in up to first discharge; and flow measurement. The next chapter provides a case history of one well in the Broadlands Geothermal Field in New Zealand, with particular reference to its drilling, measurement, discharge, and data analysis/interpretation. The changes that have occurred in exploited geothermal fields are also reviewed. The final chapter considers three major problems of geothermal reservoir engineering: rapid entry of external cooler water, or return of reinjected water, in fractured reservoirs; the effects of exploitation on natural discharges; and subsidence. This monograph serves as both a text for students and a manual for working professionals in the field of geothermal reservoir engineering. It will also be of interest to engineers and scientists of other disciplines.

Pressure and Temperature Well Testing Book Review:

The book comprises two parts: Pressure and Flow Well Testing (Part I) and Temperature Well Testing (Part II), and contains numerous authors’ developments. Due to the similarity in Darcy’s and Fourier’s laws the same differential diffusivity equation describes the transient flow of incompressible fluid in porous medium and heat conduction in solids. Therefore it is reasonable to assume that the techniques and data processing procedures of pressure well tests can be applied to temperature well tests. The book presents new methods to determine the formation of permeability and skin factors from tests conducted in simulated wells, designing interference well tests, processing constant bottom-hole pressure tests, estimation of the formation temperature and geothermal gradients from temperature surveys and logs, in-situ determination of the formation thermal conductivity and contact thermal resistance of boreholes, temperature regime of boreholes (cementing of production liners), and the recovery of thermal equilibrium in deep and superdeep wells. Processing and analysis of pressure and geothermal data are shown on numerous field examples from different regions of the world. The book is intended for students, engineers, and researchers in the field of hydrocarbon geophysics and geology, groundwater searching and exploitation, and subsurface environment examination. It will be also useful for specialists studying pressure and temperature in parametric deep and superdeep wells.

Geothermal Reservoir Engineering Book Review:

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.

Well Test Analysis and Reservoir Modeling of Geopressured geothermal Systems includes Topical Reports on Analyses for Book Review:

Automated inversion of pressure transient data from the Pleasant Bayou and Gladys McCall geopressured test wells has allowed the resolution of several outstanding questions concerning the two reservoirs. The added accuracy of the interpretation of the various data sets from each well provides convincing evidence that the formation response of each of the reservoirs behaved in an essentially linear fashion throughout its multi-year depletion/recovery test history. The only exception was in the immediate vicinity of the sandface; the skin factor in each of the wells varies during the course of its test history (see Appendices for detailed discussions of the variations and the likely causes of the variations for each well). (a) The six bottomhole pressure transient tests of Pleasant Bayou Well No. 2 over a twelve year period (1980-1992) yield estimates for the permeability-thickness product that are in excellent agreement (kh = 3.665 D-m). Inversion of the 45-day buildup portion of the 1980 RLT yields an estimate of X{sub a} = 869 m as the distance from the well to the nearest boundary. The inversion of the data from the other five tests, of much shorter duration, yield estimates in the range X{sub a} = 427-503 m. The RLT estimate would normally be given much more credence. The failure, repair and resetting of the gauge after the first ten days of the start of the buildup test, however, may have affected the RLT data. Calculations are employed to estimate bottomhole pressures from surface recordings subsequent to removal of the bottomhole gauge following the 1992 70-hr buildup test. These estimated values were combined with the 70-hr data to form the 111-day (from September 12, 1992 through January 1, 1993) LTT buildup test data set. The LTT data were inverted to yield an estimate of X{sub a} = 452 m. Since this is in agreement with the range of estimates from the five short-term bottomhole test, we believe the range X{sub a} = 427-503 m to represent the best estimate for the distance from the well to the nearest boundary. The simulation model presented in Appendix B used L1 = 990 m (Figure 3 in Appendix B) as the distance from the test well to the nearest boundary. The simulation model could probably be improved using a smaller value for L1. The actual location of the boundary to the south of the well is not known from the available geological information. (b) The five bottomhole pressure transient tests of Gladys McCall Well No. 2 over an eight-year period (1983-1991) yield estimates for the permeability-thickness product that differ significantly from each other. The differences, however, can be explained by the partial plugging of the near-well formation during an aborted attempt to inject a scale-inhibitor pill in May 1985, followed by subsequent scouring out the pill precipitates by the flowing fluid during the May 1985-August 1987 production testing. The partial plugging of the near-well formation in conjunction with a known shale stringer that prevents vertical communication in sand 8 (Figure 2 in Appendix A) would reduce the apparent value of kh to about sixty percent of the original RLT value of 13.44 D-m. Inversion of the 79-hr (1985) and 92-hr (1986) buildup tests yield kh estimates of 7.69 and 8.86 D-m, respectively. Inversions of the valid MRT (1987) and FDT (1991) pressure transient data yield estimates very near the original RLT value. The reinterpretation of the MRT data represents a correction of our earlier conclusion (in Appendix A); we now believe that the data from the first and second gauges employed during the MRT are incompatible. Data from the first (''old'') gauge during the drawdown portion of the MRT could not be adequately corrected for the observed drift in the recorded data. Only the second (''new'') gauge data are considered reliable and inversion of the buildup data it recorded yields the estimate for kh that is in agreement with estimates obtained from inversion of the RLT and FDT pressure transient data.

Rock Fractures and Fluid Flow Book Review:

Scientific understanding of fluid flow in rock fractures--a process underlying contemporary earth science problems from the search for petroleum to the controversy over nuclear waste storage--has grown significantly in the past 20 years. This volume presents a comprehensive report on the state of the field, with an interdisciplinary viewpoint, case studies of fracture sites, illustrations, conclusions, and research recommendations. The book addresses these questions: How can fractures that are significant hydraulic conductors be identified, located, and characterized? How do flow and transport occur in fracture systems? How can changes in fracture systems be predicted and controlled? Among other topics, the committee provides a geomechanical understanding of fracture formation, reviews methods for detecting subsurface fractures, and looks at the use of hydraulic and tracer tests to investigate fluid flow. The volume examines the state of conceptual and mathematical modeling, and it provides a useful framework for understanding the complexity of fracture changes that occur during fluid pumping and other engineering practices. With a practical and multidisciplinary outlook, this volume will be welcomed by geologists, petroleum geologists, geoengineers, geophysicists, hydrologists, researchers, educators and students in these fields, and public officials involved in geological projects.
