Simulação da recuperação de petróleo em reservatórios naturalmente fraturados

TL;DRAbstract

The naturally fractured reservoir recovery is a project risk specially in oil-wet or intermediate-wet systems because of the simulations results under waterflood displacement. Fractures are porous medium discontinuities with distinct capillarity and hydraulic conductivity properties that change the reservoir flow behaviour as well the physical mechanisms acting in petroleum recovery. Double-porosity models are generally used in fractured reservoir simulation and have been implemented in the major commercial reservoir simulators. The physical processes acting in pretroleum recovery are represented in double-porosity models by matrix-fracture transfer functions. Commercial simulators have their own transfer function implementations, and as a result different kinetics and final recoveries are attained. In this work, a double porosity simulator was built with Kazemi et al. (1976), Sabathier et al. (1998) and Lu et al. (2008) transfer function implementations and their recovery results comp
