| Abstract | A new computer model of the Rotorua geothermal field is described. It differs from previous models (e.g. Burnell and Kissling, 2005) by having a much finer layer structure in the shallow zone thus making it possible to more accurately represent shallow temperatures and pressures and surface activity. Two models have been set up: UOA Model 1 with a minimum block size of 250m x 250m and UOA Model 2 with a minimum block size of 125m x 125m. The calibration of UOA Model 1 is well advanced, using both manual methods and inverse modelling, and a good match to surface activity and shallow temperatures has been obtained. Calibration of UOA Model 2 is still in progress. |
