Methods of controlling water production in horizontal wells with multistage fractures
A method for controlling water passage from an interval undergoing hydraulic fracturing to another interval in the same or a different well bore. The method introduces a relative permeability modifier at a pressure sufficient to create or enhance at least one fracture and fracture face in the subterranean formation surrounding the interval during fracturing. The method can reduce the water passage between two or more intervals of a well bore and between two or more well bores. The method can reduce the amount of water produced from a well, which reduces the processing necessary to remove water from the hydrocarbons produced from the well.
