Hydrodynamic Modelling of Petroleum Reservoirs using Simulator MUFITS

An extension of MUFITS reservoir simulator for modelling oil and gas reservoirs using black-oil approach is presented. We give an overview of multi-segment well technique implemented in MUFITS for coupled reservoir-wellbore simulations. SPE comparative studies with vertical wells are simulated in order to verify the correctness of technique implementation in the code. The simulation results, in particular calculated wells bottom-hole pressures, match results of other codes.
