This book was released on 1997 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this project is to both transfer existing Hot Dry Rock two-dimensional fractured reservoir analysis capability to the geothermal industry and to extend the analysis concepts to three dimensions. In this quarter, the primary focus has been on interaction with industry, development of the Geocrack3D model, and maintenance of Geocrack2D. It is important to emphasize that the modeling is complementary to current industry modeling, in that they focus on flow in fractured rock and on the coupled effect of thermal cooling, while a primary focus of current modeling technology is multi-phase flow.

This book was released on 1998 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: System modeling supports the design and long-term, commercially successful operation of geothermal reservoirs. Modeling guides in the placement of the injection and production wells, in the stimulation of the reservoir, and in the operational strategies used to ensure continuing production. Without an understanding of the reservoir, it is possible to harm the reservoir by inappropriate operation (especially break-through of cold injection fluid) and the desired profitable lifetimes will not be reached. In this project the authors have continued to develop models for predicting the life of geothermal reservoirs. One of the goals has been to maintain and transfer existing Hot Dry Rock two-dimensional fractured reservoir analysis capability to the geothermal industry and to begin the extension of the analysis concepts to three dimensions. Primary focus has been on interaction with industry, maintenance of Geocrack2D, and development of the Geocrack3D model. It is important to emphasize that the modeling is complementary to current industry modeling, in that they focus on flow in fractured rock and on the coupled effect of thermal cooling. In the following sections the authors document activities as part of this research project: industry interaction; national and international collaboration; and model development.

Book Synopsis Thermal Performance Evaluations of Fractured and Closed-loop Geothermal Reservoirs by : Nicolás Rangel Jurado

This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earth's interior contains an enormous amount of heat that can be exploited for carbon-free direct-use or electricity generation. Even though numerous studies have predicted that geothermal power will become an important contributor to the world's energy mix, the use of these resources is still growing at a notably slow speed compared to other renewable energy alternatives. This thesis uses computational models to explore the technical challenges that two kinds of geothermal resources face to reach full commercialization. In particular, the temporal evolution of heat production of several fractured and closed-loop geothermal reservoirs is investigated. Thermal-hydraulic simulations are conducted for a fractured meso-scale geothermal reservoir in northern New York, USA. The modeling parameters considered here are constrained by empirical data related to lithology, hydrogeology, and thermal behavior measurements collected on site. This work shows how the addition of realistic complexities, that are well-constrained by field data and often disregarded, can significantly improve the thermal performance predictions compared to overly simplified models. Additionally, the results presented here highlight the importance of characterizing subsurface permeability distributions in order to optimize thermal efficiency and devise appropriate reservoir management strategies that extend the lifespan of geothermal reservoirs. To evaluate how closed-loop or advanced geothermal systems (AGS) compare to alternative ways of extracting geothermal energy, several AGS designs displaying varying reservoir and operating conditions are evaluated to estimate their heat and temperature generating potential. Our findings indicate that the thermal efficiency of AGS is characterized by a considerable exergy loss. Sensitivity analyses show that varying different parameters have slight and moderate improvements on thermal performance, however, AGS designs appear to present multiple technical challenges making them less cost-competitive than both conventional hydrothermal systems and enhanced geothermal systems (EGS). The following key findings summarize the results of these two studies: 1) if well-constrained, computational models are a good tool to assess, manage and intervene geothermal reservoirs to ensure their long-term sustainability, 2) non-uniform permeability can drastically modify fluid flow and heat transport processes in geothermal reservoirs compared to theoretical models that consider homogenous reservoir properties, 3) prospecting adequate subsurface properties is of critical importance to develop geothermal reservoirs, and 4) despite their recent popularity, closed-loop systems are expected to be considerably less productive than other types of geothermal resources at a similar scale.

Book excerpt: This book focuses on numerical modeling of deep hydrothermal and petrothermal systems in fractured georeservoirs for utilization in Geothermal Energy applications. The authors explain the particular challenges and approaches to modeling heat transport and high-throughput flow in multiply fractured porous rock formations. In order to help readers gain a system-level understanding of the necessary analysis, the authors include detailed examples of growing complexity as the techniques explained in the text are introduced. The coverage culminates with the fully-coupled analysis of real deep geothermal test-sites located in Germany and France.

This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The ultimate goal of geothermal reservoir management is to mine as much energy as possible from the reservoir. Since most of geothermal reservoirs are fractured, the development of improved techniques for monitoring, prediction and control of two-phase mass and energy transport in the fractures are needed. Tracer testing is a powerful tool for characterizing fractures properties such as swept pore volume. By incorporating the pore volume of the fracture estimated from tracer data with a semi-anaytical model of mass and energy transport in the fracture and matrix, the energy production rate can be calculated. Previous models to predict energey production assumed single-phase flow and semi-infinite matrix blocks and thus overestimate the energy that can be usufully produced from the reservoir. In this paper, a semi-analytical solution to the mass and energy balance equations is derived for two-phase flow in a fracture with heat conduction from a finite matrix. Calculations using the semi-analytical model are shown to be in good agreement with numerical simulations using the TETRAD simulator.
