Paper Number: URTEC-3705570-MS
... that any effects caused by stress-sensitivity of reservoir parameters are largely reversible. Permeability derived from all tests are much larger than those obtained from laboratory data, leading to the interpretation that natural fractures are elevating system permeability. Fracture half-lengths are also...

Paper Number: URTEC-2021-5402-MS
... Abstract In unconventional reservoirs, the existence of natural fractures is evident from the analysis of data gathered with techniques like well logs, core studies, and micro-seismic interpretation. In hydraulic stimulation of these reservoirs, propagating hydraulic fracture (HF) generally...

... and hydraulic fractures that have been analyzed. Previous works have detailed the nature of the fractures recovered in the core, identifying 375 hydraulic fractures, 309 calcite-sealed natural fractures, and 8 faults (Gale et al., 2018). We studied the likelihood for fractures to be initiated or reactivated...
