Enhanced techniques, however, intervene at a molecular level to modify the forces binding the oil to the rock matrix. Surfactants, or detergents, are injected to reduce the interfacial tension between the oil droplet and the rock surface.
Steam Flooding Thermal EOR: Maximizing Recovery Through Targeted Heat Application
Steam Flooding and Cyclic Steam Stimulation Steam flooding involves the continuous injection of steam to propagate a steam front through the reservoir, driving the oil toward production wells. By altering the physical or chemical conditions within the subsurface, operators improve the mobility and sweep efficiency of the injected displacement fluids.
This cyclic process is repeated to build pressure and enhance the cleanup of the well area. Traditional primary recovery relies on natural reservoir pressure, while secondary recovery utilizes water or gas injection to push the oil toward the wellbore.
Steam Flooding Thermal EOR: Maximizing Recovery Through Targeted Heat Application
Alkaline-Surfactant-Polymer (ASP) Flooding ASP flooding represents a sophisticated class of chemical recovery that leverages the reaction between alkali, surfactants, and polymers. These generated surfactants then lower the interfacial tension to optimal levels, while the polymer provides the necessary viscosity control.
