| Abstract |
For the last two decades, the petroleum industry has been successfully using simple inflow performance relationships (IPR's) to predict oil deliverability. In contrast, the geothermal industry lacked a simple and reliable method to estimate geothermal wells' heat deliverability. To addres this gap in the standard geothermal-reservoirassessment arsenal, we developed generalized dimensionless geothermal inflow performance relationships (GIPR's) . These "reference curvesg1 may be regarded as an approximate general solution of the equations describingthe practically important case of radial 2- phase inflow. Based on this approximate solution, we outline a straightforward approach to estimate the reservoir contribution to geothermal wells' heat and mass deliverability for 2-phase reservoirs. This approach is far less costly and in most cases as reliable as numerically modelling the reservoir, which is the alternative for 2-phase inflow. |
