Ionic Fluids for EGS: Fracture Conductivity Tests in Granite Core Samples
This dataset contains experimental measurements of fluid flow and pressure behavior during fracture conductivity tests in granite core samples. The tests were designed to evaluate various ionic and nonionic fluids, including BMiMBr, HPyBF4, HPyBr, an oil-based fluid (OBF-1), and a water-based fluid (WBF-2), under different temperature and pressure conditions relevant to geothermal systems. Data were collected at injection pressures ranging from 500 to 800 psi and temperatures from room temperature up to 80 C. Each file includes multiple sheets organized by fluid type and temperature, containing time-series measurements of pump pressures, flow rates, and volumes for confining, water injection, and intermediate fluid circuits.
