Paper Number: SPE-195220-MS
... to conventional reservoirs, unconventional reservoirs are typically characterized as highly anisotropic, heterogeneous, highly laminated, low to ultralow permeability, and containing varying quantities of natural fractures ( Soliman et al. 2010 ; Calvin et al. 2017a ). To take advantage of these resources...
