Methods to enhance gas production following a relative-permeability-modifier treatment

A method of treating a subterranean formation with a relative-permeability modifier such that gas production is enhanced following the treatment, comprising:

• introducing a treatment fluid into at least a portion of the subterranean formation, wherein the treatment fluid comprises:
• an aqueous fluid;
• the relative-permeability modifier in an amount in the range of from about 0.05% to about 1% by weight of the treatment fluid, wherein the relative-permeability modifier comprises a water-soluble polymer;
• and
• a water-drainage-rate-enhancing agent in an amount in the range of from about 0.5% to about 5% by weight of the treatment fluid.

A method of treating a subterranean formation comprising combining a water-drainage-rate-enhancing agent with a relative-permeability-modifier treatment to decrease water production from the subterranean formation, such that initiation of gas production from the subterranean formation following the relative-permeability-modifier treatment is enhanced, wherein the water-drainage-rate-enhancing agent comprises at least one compound selected from the group consisting of:

• a zwitterionic surfactant comprising an organic surfactant comprising an alkyl chain length of from about 12 to about 22 carbons, a cationic group, and an anionic group;
• a cationic polyorganosiloxane comprising at least two quaternary ammonium groups;
• a nonionic surfactant selected from the group consisting of:
• an organic surfactant having the structure shown below:
• R6—O[(EO)p—(PrO)q—(BuO)r]H
• wherein R6 is an alcohol, phenol or phenol derivative or a fatty acid comprising about 12 to about 22 carbons, EO is an ethylene oxide radical, p is 1 to 20, PrO is a propylene oxide radical, q is 0 to 15, BuO is a butylene oxide radical, and r is 0 to 15;
• an organic polyethylene carbonate having the structure shown below:
• wherein R7 is an alcohol comprising from about 7 to about 16 carbons and s is 7 to 16:
• a butoxylated glycol comprising 1 to 15 butylene oxide groups;
• and
• an ethoxylated-butoxylated glycol comprising 1 to 5 ethylene oxide groups and 5 to 10 butylene oxide group;
• and
• any combination thereof.
