Bouguer gravity anomaly contour map

A Bouguer gravity anomaly contour map was compared to geothermal gradients from wells at various depths. High geothermal gradient wells generally coincide with gravity anomalies. Wells with lower geothermal anomalies, however, might not be relevant because of the cooling effects of circulating drilling muds for those wells, which were not shut in for sufficiently long periods of time. In general, for the Salton Trough region, gravity data seems to provide the most reliable indicator for geothermal resources.  More »
