report description
The characteristics of the Hawaii Geothermal Project well HGP-A were presented last year in terms of flow rates under throttled conditions, downhole pressure and temperature profiles, and pressure drawdown and buildup tests. In particular, the more recent pressure buildup analyses have indicated the possibility of multiple production zones. In an attempt to locate these production zones, two tests have been conducted during the past six months.
