Modeling of the waterflooding process in the presence of discontinuities in the oil reservoirs

Abstract

The knowledge of the nature of flooding allows us to optimize the system of oilfield development. The study of the filtration process in reservoirs with discontinuities, such as highly permeable cracks or impermeable barriers, has a great importance for the oilfield development. The steady-state flow process of incompressible fluid to the production well in a reservoir of constant height and permeability is considered. There is a thin area in the reservoir, which might be a highly permeable crack or impermeable barrier. The production and injection wells are placed inside the reservoir’s external boundary. The characteristics of flooding process are studied for different locations of the discontinuity and a pair of wells. The flow lines of the fluid flow will be analyzed for every considered case.
