Conference Proceedings: Evaluation of testing and reservoir parameters in geothermal wells at Raft River and Boise, Idaho

Abstract
Evaluating the Raft River and Boise, Idaho, resources by pump and injection tests require information on the geology, geochemistry, surficial and borehole geophysics, and well construction and development methods. Nonideal test conditions and a complex hydrogeologic system prevent the use of idealized mathematical models for data evaluation in a one-phase fluid system. An empirical approach is successfully used since it was observed that all valid pump and injection well pressure data for constant discharge tests plotted as linear trends on semilogarithmic plots of borehole pressure versus time since pumping or injection began. Quantification of the pressure response prior to 600 minutes is not always possible. Short-duration (< 24-hour) injection or pump tests are conducted with the drilling rig equipment, and long-duration (21-day) injection and pump tests are then conducted with the permanent pumping facilities. Replicate instrumentation for pressure, temperature, and flow rates is necessary to ensure quality data. Water quality and monitor well data are also collected.
