ABSTRACT:
A method for enhancing the production of liquid hydrocarbons from oil-wet, fractured reservoirs comprising injecting a surfactant solution into the reservoir, pressurizing the reservoir, maintaining the pressure, and recovering liquid hydrocarbons. In an embodiment, the method comprises closing production wells for a period to maintain reservoir pressure and surfactant exposure within the matrix.
