    摘要: Treatment fluids may include an aqueous fluid, a microemulsion surfactant, and an amphiphilic polymer that itself includes a hydrophobic component and a hydrophilic component. Such treatment fluids may be utilized in subterranean formations such that the microemulsion surfactant forms a microemulsion that comprises the amphiphilic polymer within the subterranean formation.

    摘要: Stabilized emulsion compositions comprising an oleaginous fluid, a fluid that is at least partially immiscible with the oleaginous fluid, and, an emulsion stabilizing agent. The emulsion stabilizing agent comprises a first ionic compound soluble in the oleaginous fluid or the fluid that is at least partially immiscible with the oleaginous fluid and a second ionic compound with a charge of opposite sign of the first ionic compound and that is at least partially soluble in the opposite fluid as the first ionic compound. The first ionic compound and the second ionic compound are selected from the group consisting of: a cationic ionic surfactant, an anionic surfactant, a cationic polyelectrolyte, an anionic polyelectrolyte, and a combination thereof.
