... (DDA) concept and assumes that the reservoir consists of two regions: a primary hydraulic fracture (PHF) and an adjacent enhanced fracture region (EFR) or non-stimulated region (NSR) in the reservoir. Assuming a well pair primarily communicates through PHFs, the equations for two communicating wells...

.... The numerical errors are even larger for two-phase flow, when suddenly a grid-block drops below the bubblepoint pressure. Another question is related to approximations associated with the pseudo-steady state formulations in the wellbore block (e.g. the Peaceman equation). To eliminate these potential...
