Exploration Basis

This study was conducted to help define the ground fluids that were flowing into the well HGP-A.

Notes

A Mise-A-La-Masse survey was conducted utilizing the well casing of HGP-A as an electrode. The electrical source was directly connected to the well casing and the return electrode was grounded roughly six km away in the ocean. The purpose of this survey was to help define the reservoir boundaries and hydrothermal system feeding the well. Electrical potentials were measured at distances up to 2 km from the well. The well has casings along its entire length however only the top 670 m were electrically continuous. The resistivity data showed that there is a dike-impounded compartment of high resistivity freshwater that is warm and overlies the actual reservoir. The water is confined by zones that are hot and most likely consist of dike complexes.
