Collection and Analysis of Reservoir Data from Testing and Operation of the Raft River 5 MW Power Plant
Description: The Raft River 5 MW power plant will be on-line some time this spring. During testing of the supply and injection system prior to plant start-up and during testing of the plant itself, data can be collected and used to calibrate computer models, refine predicted drawdowns and interference effects, monitor changing temperatures, and recalculate reservoir parameters. Analytic methods have been used during reservoir testing at Raft River to calculate reservoir coefficients. However, anisotropy of the reservoir due t o fractures has not been taken into account i n these calculations and estimates of these coefficients need to be refined. From refined estimates of reservoir coefficients better predictions of interference effects and long-term drawdown in the wells can be made. In conjunction with the USGS, Faust and Mercer's 3-D finite difference model has been used to simulate the Raft River geothermal field. Intera used a 2-D simulator to predict temperatures, pressures over 30 years and movement of dissolved solids in the reservoir. Data collected during production of the field will be compared to these simulations and the models refined.
