He stated that LCM test, where the cutter forces are measured by full-size cutters in large It is known that rock properties and their influence on rock samples, combined with rock physical property tests rock cutting and boring is crucial...

... type A rocks with lower inclination of the fractures. Rocks with micro-fractures have permeability hysteresis, which especially happens to rock samples with the narrowest fracture width, resulting in stronger stress sensitivity effect. This work gives insight to estimate stress-dependent permeability...

... quickly from the radial borehole axes while enhancing the distances. Rock samples with azimuths of 30° can create hydraulic fractures cutting through two layers of radial boreholes, even if the distances are 24 times the diameters of radial boreholes. But when the distances are more than 16 times...

... Abstract Currently, acid etching and conductivity experiments mostly use smooth rock samples to simulate the formation of acid fractures. There are few reports on the influence of fracture rough morphology on acid etching behavior and conductivity. In this paper, digital carving technology...

..., and fluids transport. The measurement of permeability of Bakken rock samples is very challenging due to their extremely low permeability. In this study, we investigate the permeability of a number of Bakken core samples using oscillating-pulse and pulse-decay methods and then compare them with the steady...
