| dc.description.abstract | Water injection is one of the Enhanced Oil Recovery (EOR) methods aimed at maintaining
reservoir pressure and improving sweep efficiency. One of the key parameters for the success of water
injection is throughput, which represents the volume of fluid that can flow through a porous medium
over a certain period of time. This study aims to analyze throughput during the water injection
process into reservoir rocks by considering factors such as permeability, injection pressure, and fluid
viscosity.Experiments were conducted on core samples with varying permeability and injection
pressure. Data were obtained using the core flooding method to evaluate the relationship between
absolute permeability, relative permeability, and water injection rate. The results indicate that
throughput increases significantly with higher injection pressure and rock permeability. However,
under certain conditions, the presence of residual oil in the rock pores reduces water flow
effectiveness due to capillary trapping and saturation hysteresis effects. | en_US |
