Modeling, design, and life performance prediction for energy production from geothermal reservoirs. August 1997 progress report

Description: 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.

Modeling, design, and life performance prediction for energy production from geothermal reservoirs. Final report

Description: 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.

Modeling, design, and life performance prediction for energy production from geothermal reservoirs. Quarterly report, January--March 1998

Description: The objective of this project is to maintain and transfer existing Hot Dry Rock two-dimensional fractured reservoir analysis capability to the geothermal industry and to extend the analysis concepts to three dimensions. The project start date was May 22, 1997 and it runs through May 21, 1998. This is the quarterly progress report for January through March of 1998. In this quarter, the primary focus has been on development of the Geocrack3D model, presenting initial results to the industry, and maintenance of Geocrack2D. It is important to emphasize that the modeling is complementary to current industry modeling, in that they focus on the user interface, flow in fractured rock, and the coupled effect of thermal cooling changing fracture aperture.
