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...

... increases from nanodarcy to micro darcy scale, leak-off and invasion of hydraulic water increase substantially. The application of geomechanics in opening and closing natural fractures with pressure has a significant effect on water distribution inside reservoirs and the production of fluids. The natural...

Paper presented at the SPE/AAPG/SEG Unconventional Resources Technology Conference, July 26–28, 2021
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...

... fractures, most having fibrous cement (beef), and some showing top-to-north bed-parallel shear are present. Faults with normal/oblique movement were found in one part of the core. Drilling induced and core-handling breaks were identified in all cores, and were also noted to have reactivated some natural...
