Fracturing Parameters in Petroleum Reservoirs and Simulation

The increasing demand for crude oil makes it necessary to consider factors that increase the productivity of the reservoirs. One of these factors is fracture that is found naturally or produced hydraulically, where the fracture improves reservoir flow and connectivity. The most common characteristics of naturally fractured reservoirs (NFRs) are the fractures directionality. In this review, the most important characteristics and parameters that affect the fracture have been explained. In addition, the simulations of the fracture phenomena have been cleared. The difference among the models that solved the fracture problems are; discrete fracture model (DFM), dual porosity model (DPM), embedded discrete fracture model (EDFM), and hybrid models DP and EDFM (DP + EDFM) are shown with characteristics of each model. The present study focused on the shape factor and the direction of the fracture to show their effects on the performance of the petroleum reservoir. In addition, the review of general important parameters for the fractured reservoirs has been presented.
