Description
Secondary oil recovery is an essential stage in petroleum reservoir management, aimed at
extracting residual oil that remains trapped in porous formations after primary recovery. Water
flooding is one of the most widely used secondary recovery techniques; however, the efficiency
of oil displacement depends strongly on the porous medium's structural characteristics,
permeability, fluid properties, and inclination. The present study investigates the influence of
inclination in porous media on fluid flow and oil displacement during secondary oil recovery.
Attention is given to the effects of gravitational forces, viscous forces, and permeability
variations on the movement of injected water through the porous medium. A mathematical
model based on the governing equations of fluid flow in porous media can be developed to
describe the coupled transport of oil and water under inclined conditions in the form of partial
differential equation with appropriate initial and boundary condition. Semi analytical and
approximate solution techniques namely Optimal homotop analysis method be employed to
examine the saturation distribution, fluid velocity, and displacement efficiency for different
inclination angles and reservoir parameters. The study aims to identify how the inclination of
the porous medium influences the recovery process and the distribution of residual oil. The
findings are expected to provide useful insights into the role of reservoir geometry in improving
secondary oil recovery strategies and optimizing fluid injection processes
