摘要:
Of the many methods and compositions provided herein, in one embodiment, the invention provides a method comprising: providing an oil-wet well bore surface; providing a surfactant wash treatment fluid that comprises an acid-compatible surfactant, an acid and/or an acid-generating component, and an aqueous fluid; contacting the oil-wet well bore surface with the surfactant wash treatment fluid; allowing the oil-wet well bore surface to become water-wet; and producing fluids from the formation. In another embodiment, the invention provides a surfactant wash treatment fluid for use in a subterranean formation comprising an aqueous fluid, an acid-compatible surfactant, an acid and/or an acid-generating component.
