The Hawaii Play Fairway Project deepened an already existing water well in Palawai Basin, Lanai island. Lanai Well #10 was deepened from 427 m to ~1057 m, with nearly continuous rock core collected. Spanning the dates from May 13 to July 5, 2019, the daily drilling reports of Lanai Well #10 includes a log of events during drilling and well information (e.g. location, elevation, and casing). A project by the University of Hawaii at Manoa, the Hawaii Play Fairway project was funded by the U.S. Department of Energy Geothermal Technologies Office (award DE-EE0006729).
