Review of the Hawaii Play Fairway Phase 2 Activities

The Hawaii Play Fairway project, funded by the U.S. Department of Energy, comprises three Phases. In Phase 1, existing geologic, groundwater, and geophysical datasets relevant to subsurface heat, fluid and permeability were identified, compiled, and ranked. We also developed a statistical methodology to integrate these data into a resource probability map. Phase 2 of the project has involved the collection of new groundwater data in ten prospective regions across the state; collection of new geophysical data on Lanai, Maui, and central Hawaii Island; and modeling of topographically induced stresses the last to better characterize permeability. Phase 2 data were incorporated into an updated resource probability map. Here, we present results of the Phase 2 data collection and modeling activities, and comment on Phase 3 plans.
