METHODS TO ENHANCE GAS PRODUCTION FOLLOWING A RELATIVE-PERMEABILITY-MODIFIER TREATMENT

摘要

Disclosed embodiments relate to introducing a water-drainage-rate-enhancing agent into a subterranean formation to enhance gas production following a relative-permeability-modifier treatment to decrease undesired water production. An exemplary embodiment provides a method of treating a subterranean formation such that initiation of gas production is enhanced following the treatment, the method comprising: introducing a relative-permeability modifier into at least a portion of the subterranean formation such that the relative-permeability modifier reduces permeability of the portion to aqueous fluids; and introducing a water-drainage-rate-enhancing agent into at least a portion of the subterranean formation. Another exemplary embodiment of the present invention provides a treatment fluid comprising a carrier fluid, a relative-permeability modifier, and a water-drainage-rate-enhancing agent.
