Abstract
Methods for oil and/or gas production may employ mixed surfactants to treat a subterranean formation. The methods can comprise: providing a treatment fluid comprising: an aqueous base fluid, a first surfactant having a charge, a second surfactant having an opposite charge, and a compatibilizer; and introducing the treatment fluid into at least a portion of the subterranean formation.
Claims17
A method comprising:
- providing a treatment fluid consisting essentially of:
- 1) an aqueous base fluid, a first surfactant having a charge, a second surfactant having an opposite charge, and a compatibilizer, or
- 2) an aqueous base fluid, a first surfactant having a charge, a second surfactant having an opposite charge, a compatibilizer, and an additive selected from the group consisting of a corrosion inhibitor, a particulate, an acid, a breaker, a scale inhibitor, a clay stabilizer, and any combination thereof;
- and
- wherein the compatibilizer comprises a nonionic surfactant or an amphoteric surfactant and wherein the compatibilizer prevents precipitation from the interaction of the first surfactant having a charge with the second surfactant having an opposite charge;
- introducing the treatment fluid into at least a portion of a subterranean formation.

A method comprising:
- providing a fracturing fluid comprising:
- an aqueous base fluid,
- proppant particulates,
- a first surfactant having a charge,
- a second surfactant having an opposite charge, and
- a compatibilizer, wherein the compatibilizer comprises a nonionic surfactant or an amphoteric surfactant and wherein the compatibilizer prevents precipitation from the interaction of the first surfactant having a charge with the second surfactant having an opposite charge;
- and
- introducing the fracturing fluid into at least a portion of a subterranean formation at a rate and pressure sufficient to create or enhance at least one or more fractures in the subterranean formation.
5 more elements
A method comprising:
- providing a fracturing fluid comprising:
- an aqueous base fluid,
- a first surfactant having a charge,
- a second surfactant having an opposite charge, and
- a compatibilizer, wherein the compatibilizer comprises a nonionic surfactant or an amphoteric surfactant and wherein the compatibilizer prevents precipitation from the interaction of the first surfactant having a charge with the second surfactant having an opposite charge;
- and
- introducing the fracturing fluid into at least a portion of a subterranean zone comprising a first rock having an affinity for the first surfactant and a second rock having an affinity for the second surfactant, the first rock comprising a siliceous mineral and the second rock comprising a carbonate mineral.
