Book excerpt: The early time response in the well testing of an homogeneous reservoir is expected to give a unit slope when log (pressure) is plotted versus log (time). It is shown that this response is a special case, and that in general another non-dimensional parameter must be defined to describe the set of curves that could take place for each value of C/sub D/. This parameter, t/sub Rw/, is the time response of the reservoir divided by the time response of the well. When t/sub Rw/ is large, a unit slope results (as in oil and gas fields where kh/.mu. is relatively low) while no unit slope should be measured for small values of t/sub Rw/ (as in geothermal fields where kh/.mu. is much larger than in an oil field). Using a numerical model of transient two-phase flow, the predicted early time behavior in well testing has been plotted for C/sub D/ = 25, 100, and for values of t/sub Rw/ = 10, 1, 0.1 in each case. It is shown that both C/sub D/ and t/sub Rw/ are needed to correlate the behavior. In addition, the effect of heat transfer on the downhole pressure change with time has been calculated using the assumption of thermodynamic equilibrium. If the well test data is analyzed without taking into account the heat loss, the calculations for kh/.mu. are wrong. It is also postulated that non-equilibrium effects in the well many lead to abrupt changes in the pressure versus time curve. Such changes have been observed in field tests of flashed geothermal systems.

Download or read book Geothermal Reservoir Engineering written by Malcomm Grant and published by Elsevier. This book was released on 2013-02-07 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: In the past year a number of studies pertaining to geothermal well test analysis were conducted. In this paper a brief overview of progress on the following six subjects is presented: (1) earth tide effects on a closed reservoir, (2) transient pressure analysis of multilayered heterogeneous reservoirs, (3) interference testing with wellbore storage and skin at the producing well, (4) steam/water relative permeabilities, (5) transient rate and pressure buildup resulting from constant pressure production, and (6) transient pressure analysis of a parallelepiped reservoir.

Available in PDF, EPUB and Kindle. Book excerpt: Geothermal Well Test Analysis: Fundamentals, Applications and Advanced Techniques provides a comprehensive review of the geothermal pressure transient analysis methodology and its similarities and differences with petroleum and groundwater well test analysis. Also discussed are the different tests undertaken in geothermal wells during completion testing, output/production testing, and the interpretation of data. In addition, the book focuses on pressure transient analysis by numerical simulation and inverse methods, also covering the familiar pressure derivative plot. Finally, non-standard geothermal pressure transient behaviors are analyzed and interpreted by numerical techniques for cases beyond the limit of existing analytical techniques. Provides a guide on the analysis of well test data in geothermal wells, including pressure transient analysis, completion testing and output testing Presents practical information on how to avoid common issues with data collection in geothermal wells Uses SI units, converting existing equations and models found in literature to this unit system instead of oilfield units

Available in PDF, EPUB and Kindle. Book excerpt: Although not the first hot-water geothermal field under development, the Broadlands geothermal field has shown itself to be quite different in behavior to other hot-water fields. The field was discharged some five years between 1966 and 1971, and has provided a large source of data in its as yet undeveloped state. This paper presents some of the results inferred from well-testing and highlights (1) the complexity of the system, (2) the importance of wellbore storage effects and (3) the effects of reinjection.
Download or read book Geothermal Energy written by Ingrid Stober and published by Springer Nature. This book was released on 2021-05-24 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: The internal heat of the planet Earth represents an inexhaustible reservoir of thermal energy known as Geothermal Energy. The 2nd edition of the book covers the geologic and technical aspects of developing all forms of currently available systems using this "renewable" green energy. The book presents the distribution and transport of thermal energy in the Earth. Geothermal Energy is a base load energy available at all times independent of climate and weather. The text treats the efficiency of diverse shallow near surface installations and deep geothermal systems including hydrothermal and petrothermal techniques and power plants in volcanic high-enthalpy fields. The book also discusses environmental aspects of utilizing different forms of geothermal energy, including induced seismicity, noise pollution and gas release to the atmosphere. Chapters on hydraulic well tests, chemistry of deep hot water, scale formation and corrosion, development of geothermal probes, well drilling techniques and geophysical exploration complete the text. This book, for the first time, covers the full range of utilization of Geothermal Energy.

This book was released on 2024-07-17 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the evolving environment of energy extraction, the conventional mindset that prioritizes profitability at the expense of safety and environmental concerns is becoming increasingly obsolete. The outdated dichotomy between economic gains and ecological responsibility not only risks environmental incidents but also undermines corporate standing and shared values. With stringent Environmental, Social, and Governance (ESG) requirements and energy transition imperatives, oil and gas operators in unconventional Fields face the challenge of navigating a web of compliance and sustainability mandates. There is a need for a paradigm shift, a comprehensive framework that integrates profitability, technological efficacy, and ecological compatibility for the sustainable exploration, development, and operation of unconventional oil and gas fields. Sustainability Applied to Unconventional Oil and Gas Field Exploration and Development, is a groundbreaking book designed to usher in this paradigm shift. This work presents a robust life cycle concept, offering a holistic framework that not only breaks free from the archaic mindset but also propels the industry towards a future where profitability and environmental responsibility are inseparable. The book provides oil and gas operators and the scientific community with a consultative source, delving into specific technologies that promote the swift implementation of economically profitable, technically effective, and ecologically compatible measures. By encouraging problem-solving discussions among stakeholders, including R & D teams, communities, and regulatory bodies, the book envisions a collaborative approach that benefits company stakeholders, local communities, and society at large without compromising the business's bottom line.
