... fracture size is important for spacing effects, we consider the cases with longest half-length. Oil recovery starts to degrade only when spacing is less than 600 ft for scenario 3, or 700 ft for the others. We explain that the high permeability SRV regions dampen the pressure depletion, and hence...
