Modeling of heat extraction from variably fractured porous media in Enhanced Geothermal Systems

Journal Article Hadgu, Teklu ; Kalinina, Elena Arkadievna ; Lowry, Thomas Stephen - Geothermics

Modeling of heat extraction in Enhanced Geothermal Systems is presented. The study builds on recent studies on the use of directional wells to improve heat transfer between doublet injection and production wells. The current study focuses on the influence of fracture orientation on production temperature in deep low permeability geothermal systems, and the effects of directional drilling and separation distance between boreholes on heat extraction. The modeling results indicate that fracture orientation with respect to the well-pair plane has significant influence on reservoir thermal drawdown. As a result, the vertical well doublet is impacted significantly more than the horizontal wellmore » doublet« less

An Assessment of Some Design Constraints on Heat Production of a 3D Conceptual EGS Model Using an Open-Source Geothermal Reservoir Simulation Code

Conference Xia, Yidong ; Plummer, Mitch ; Podgorney, Robert ; ...

Performance of heat production process over a 30-year period is assessed in a conceptual EGS model with a geothermal gradient of 65K per km depth in the reservoir. Water is circulated through a pair of parallel wells connected by a set of single large wing fractures. The results indicate that the desirable output electric power rate and lifespan could be obtained under suitable material properties and system parameters. A sensitivity analysis on some design constraints and operation parameters indicates that 1) the fracture horizontal spacing has profound effect on the long-term performance of heat production, 2) the downward deviation anglemore »« less

MASSIVELY PARALLEL FULLY COUPLED IMPLICIT MODELING OF COUPLED THERMAL-HYDROLOGICAL-MECHANICAL PROCESSES FOR ENHANCED GEOTHERMAL SYSTEM RESERVOIRS

Conference Podgorney, Robert ; Huang, Hai ; Gaston, Derek

Development of enhanced geothermal systems (EGS) will require creation of a reservoir of sufficient volume to enable commercial-scale heat transfer from the reservoir rocks to the working fluid. A key assumption associated with reservoir creation/stimulation is that sufficient rock volumes can be hydraulically fractured via both tensile and shear failure, and more importantly by reactivation of naturally existing fractures (by shearing) to create the reservoir. The advancement of EGS greatly depends on our understanding of the dynamics of the intimately coupled rock-fracture-fluid system and our ability to reliably predict how reservoirs behave under stimulation and production.

Challenges for Numerical Modeling of Enhanced Geothermal Systems

Journal Article Fairley, J P ; Ingebritsen, S E ; Podgorney, R K - Ground Water

A recent guest editorial by Wood (2009) pointed out the potential of enhanced geothermal systems (EGS) as a future source of “green” energy and suggested that EGS offers research opportunities for hydrogeologists seeking to become involved in the world’s energy future. Although EGS may have a bright future as a sustainable, low-carbon emission energy source, significant technical challenges must be overcome before this promising energy resource can be commercially viable. Because pilot EGS projects in the United States face very different economic constraints than current European projects, there is a real need to make technological advances to improve the returnmore »« less
GEOTHERMAL / SOLAR HYBRID DESIGNS: USE OF GEOTHERMAL ENERGY FOR CSP FEEDWATER HEATING

Conference Turchi, Craig ; Zhu, Guangdong ; Wagner, Michael ; ...

This paper examines a hybrid geothermal / solar thermal plant design that uses geothermal energy to provide feedwater heating in a conventional steam-Rankine power cycle deployed by a concentrating solar power (CSP) plant. The geothermal energy represents slightly over 10% of the total thermal input to the hybrid plant. The geothermal energy allows power output from the hybrid plant to increase by about 8% relative to a stand-alone CSP plant with the same solar-thermal input. Geothermal energy is converted to electricity at an efficiency of 1.7 to 2.5 times greater than would occur in a stand-alone, binary-cycle geothermal plant usingmore »« less
