Paper presented at the SPE/AAPG/SEG Unconventional Resources Technology Conference, June 13–15, 2023
Paper Number: URTEC-3864802-MS
... Abstract In past studies, changes in fluid pressure in natural fractures (planes of weakness) have been ignored for the interaction of hydraulic and natural fractures. To overcome these limitations, in this paper we develop a method to simulate the growth of hydraulic fractures...

... for a formation with such low porosity. Limited core data shows that the natural fractures are well-developed and may strongly enhance the permeability of the tight reservoir. The testing results also show that the subsurface reservoir exhibits high pressure and high temperatures (HPHT). Fractures observed...

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...
