This dataset contains results from four fluid injection experiments at 24 C, 69 C, 111 C, and 140 C using a triaxial loading apparatus ("Temco"). Tests were conducted on a Utah FORGE granite sample with a 30 degree inclined fracture. Confining pressure was maintained at 10 MPa, while shear stress was reduced to create a zero-displacement condition, which means the shear stress decreases continuously. Pore pressure was increased stepwise at 300 kPa every six minutes to simulate injection. Temperature was rapidly raised by voltage heating and then stabilized. Data are provided in spreadsheet format, with one file per temperature. Each file contains upstream and downstream measurement sheets with columns for pressure, flow rate, displacement, and time, with units specified in the headers.
