...) fracture subsystem, and (3) wellbore subsystem. Incorporating with frictional and acceleration pressure drops, a mathematical model with finite horizontal well conductivity (HWC) was established. Employing Laplace transform, the mathematical model was solved. Transient pressure solutions of MFHW were...

... in a porous medium, through the two-phase case, up to the three-phase black oil model. The starting point is based on a mathematical model that is an extension of Biot's theory for flow in porous media, and which accounts for coupling the reservoir of fluid flow to the rock deformation and stress states...
