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

PDF Version Also Available for Download.

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 ... continued below

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.
