Abstract

Reservoir simulation is an important tool that can be used to simulate as well as predict production from shale reservoirs. The type of reservoir simulation model used, is significant in this process. Black-oil and compositional simulators can be used for reservoir simulation. Blackoil simulations are easier and less time-consuming than compositional simulations. However, how accurate are black-oil simulation results compared to compositional simulation results? Can we afford to jeopardize the accuracy of production forecasts by using easier and less timeconsuming reservoir simulation methods? Can the results be trusted to some extent? Singlephase and two-phase black-oil simulation results as well as compositional simulation results were analyzed and compared in this article.
