Paper Number: ARMA-2021-1245
... in unconventional reservoir requires comprehensive knowledge of the rock characteristics, such as pore size distribution. In this work we presented the results of digital rock analysis (DRA) for high-resolution micro-CT and FIB-SEM images of Bakken core plugs. The workflow includes a fundamental digital rock...

...), the former Homestake Gold Mine. Multiple cameras, each capable of monitoring a 100 m (350 ft) length of mine drift, have demonstrated a measurement resolution of 0.12 mm (0.005 in)-sufficient for correlating measured vibrations to periodic pumping intervals in a water pipe. The system was then deployed...
