Abstract: A method of treating a reservoir penetrated by at least one well involves placing a consolidated solids pack into a permeable zone of rock in the reservoir. The consolidated solids pack has a reduced permeability to water and a reduced mobility in the permeable zone. For example, when placed in the permeable zone in connection with a water flooding operation, the consolidated solids pack diverts the injectant from the permeable zone to other less permeable zones of the reservoir that contain oil.

Abstract: Systems, compositions, and methods for reducing the production of water in subterranean formations having fractures or voids therein are provided. In one embodiment, the methods comprise: introducing a particulate material into a portion of a subterranean formation comprising one or more fractures or voids; and introducing a treatment fluid comprising a relative permeability modifier into the portion of the subterranean formation such that the permeability of the particulate material in the portion of the subterranean formation to water is reduced.

Abstract: Methods comprising identifying an interval of a subterranean formation to be treated, the interval comprising multiple portions, each portion having a different effective permeability; introducing a relative-permeability modifier into the interval; and, introducing a sealant into the interval. The relative-permeability modifier modifies the interval to have a more uniform effective permeability to water-based fluids. The relative-permeability modifier comprises a water-soluble polymer. The more uniform effective permeability of the interval allows for a more uniform treatment of the interval by the sealant than would be allowed without treatment of the interval with the relative-permeability modifier.
