ABSTRACT:
This invention relates to a method of terminating the undesirable flow of water from a highly permeable portion of a portion of or a fracture in a subterranean formation into a wellbore, which method involves the use of a hydraulic cement consisting of discrete particles having a particle size not greater than about 30 microns. The cement, which is utilized in a slurry of a hydrocarbon liquid and a surfactant, has a low density, good thixotropic properties and, in one embodiment, expansive characteristics.
