Methods for protecting a hydrocarbon-producing zone of a subterranean formation using a relative permeability modifier

摘要

A relative permeability modifier may be used to protect a hydrocarbon-producing zone of a subterranean formation without detrimentally affecting its ability to produce hydrocarbons. Methods for protecting a hydrocarbon-producing zone of a subterranean formation can comprise: introducing a first treatment fluid comprising a relative permeability modifier to a hydrocarbon-producing zone of a subterranean formation also comprising a water-producing zone; concurrently with or after introducing the first treatment fluid to the hydrocarbon-producing zone, introducing a second treatment fluid comprising a sealant composition to the water-producing zone; and allowing the relative permeability modifier to substantially prevent the sealant composition from entering the hydrocarbon-producing zone.

1. A method comprising:
introducing a first treatment fluid comprising a relative permeability modifier to a hydrocarbon-producing zone of a subterranean formation also comprising a water-producing zone;
wherein the relative permeability modifier reduces production of water without substantially reducing production of hydrocarbons from the hydrocarbon-producing zone; concurrently with or after introducing the first treatment fluid to the hydrocarbon-producing zone, introducing a second treatment fluid comprising a sealant composition to the water-producing zone; and allowing the relative permeability modifier to substantially prevent the sealant composition from entering the hydrocarbon-producing zone.
