... the flow in perforation tunnels with flow in the wellbore itself, to obtain a more accurate estimate of maximum sand free production rate in a well. The elastic equations of equilibrium are combined with the Mohr–Coulomb failure criterion to calculate the critical radius. A numerical, iterative solution...

Paper Number: SPE-191813-18ERM-MS
.... Orientation of the fracture model can be adjusted from vertical to inclined positions. Four injection points perpendicular to the wellbore were used to simulate injection through multiple perforations, in addition to single point injection scenarios. Equilibrium dune height (EDL) is expressed in three...

... Abstract The modern hydraulic fracturing process in unconventional shales has relied mainly on the use of mechanical isolation techniques (frac plugs) for internal isolation in between multi-cluster perforated frac stages. Significant benefits exist if mechanical frac plugs can be successfully...

One method is to simply perforate the Grimsby and hope the hydraulic fracture reaches and develops into the Whirlpool. Another completion option is to treat the Whirlpool and Grimsby with two separate...
