This report describes minifrac tests conducted in the 16B(78)-32 well at the Utah FORGE site to characterize subsurface stresses, including the magnitude and orientation of the minimum and maximum horizontal stresses and the magnitude of the vertical stress. A minifrac test was conducted at seven different depths in the 9-5/8-inch diameter open (uncased) 16B(78)-32 borehole from June 22 to July 2, 2023. The minifrac tests were conducted using Baker Hughes Reservoir Characterization (RCX) straddle-packer tool. Borehole circulation was performed prior to conducting the minifrac tests to protect the test equipment from high temperatures. Part of the data interpretation process included adjusting stresses for thermal cooling effects caused by fluid circulation.
