Energy Extraction Experiments in the SGP Reservoir Model

PDF Version Also Available for Download.

Description

Experiments are being conducted in the Stanford Geothermal Program (SGP) large geothermal reservoir model utilizing rock systems with several characteristics resembling high permeability, fracture-stimulated systems. The broad objective of these experiments is to evaluate nonisothermal fluid production and heat transfer processes and to analytically model these for such rock systems. Three nonisothermal energy extraction and production processes, referred to here as in-place boiling, sweep, and steam-drive, were considered during the early phases of this study. The results showed that all three processes are feasible in the experimental systems considered. However, the effectiveness of the processes varied widely. The simple analytic ... continued below

Description

Experiments are being conducted in the Stanford Geothermal Program (SGP) large geothermal reservoir model utilizing rock systems with several characteristics resembling high permeability, fracture-stimulated systems. The broad objective of these experiments is to evaluate nonisothermal fluid production and heat transfer processes and to analytically model these for such rock systems. Three nonisothermal energy extraction and production processes, referred to here as in-place boiling, sweep, and steam-drive, were considered during the early phases of this study. The results showed that all three processes are feasible in the experimental systems considered. However, the effectiveness of the processes varied widely. The simple analytic models developed for the model reservoir and for the heat transfer from the rock successfully predicted the experimental results as long as the assumptions inherent in the models were not seriously violated. However, it was recognized that more detailed experimental and analytic studies of the heat transfer aspects were required, and such studies have since been performed by Iregui [Reference 4]. The final report of these results is in preparation and the highlights are given below. 2 tabs., 5 refs., 4 figs.
