Reservoir simulation with the MUFITS code: extension for horizontal wells and fractured reservoirs

Two new modelling options developed recently within the MUFITS reservoir simulator are presented. The first wellbore friction option allows a simplified modelling of wellbore hydraulics that often needs to be accounted for in horizontal wells. The second option concerns the modelling of fractured reservoirs using the double porosity, the double permeability and more general multiple interacting continua approaches. Results of the options validation against benchmark problems are presented and internal structures that MUFITS builds in kernel for such reservoir models are demonstrated.
