FLUID MOBILITY MODIFIERS FOR INCREASED PRODUCTION IN SUBTERRANEAN FORMATIONS

摘要

Embodiments including methods comprising providing a treatment fluid comprising a first aqueous base fluid and a polymeric gelling agent, wherein the treatment fluid comprises a first surface tension; introducing a fluid mobility modifier into the treatment fluid, wherein the fluid mobility modifier comprises: a first surfactant selected from the group consisting of a non-ionic surfactant; a cationic surfactant; and any combination thereof, and a solvent-surfactant blend comprising a second aqueous base fluid, a second surfactant, a solvent, and a co-solvent, wherein the ratio of the first surfactant to the solvent-surfactant blend is in the range of between about 1:5 to about 5:1, wherein the fluid mobility modifier causes the treatment fluid to adopt a second surface tension that is less than the first surface tension; and introducing the treatment fluid into a subterranean formation.

1. A method comprising:
providing a treatment fluid comprising a first aqueous base fluid and a polymeric gelling agent selected from the group consisting of a derivatized guar gum, a cellulose derivative, xanthan, succinoglycan, alginate, chitosan, and any combination thereof,
wherein the treatment fluid comprises a first surface tension; introducing a fluid mobility modifier into the treatment fluid,
wherein the fluid mobility modifier comprises:
a first surfactant selected from the group consisting of a non-ionic surfactant; a cationic surfactant; and any combination thereof, anda solvent-surfactant blend comprising a second aqueous base fluid, a second surfactant, a solvent, and a co-solvent,
wherein the solvent-surfactant blend is an oil-in-water microemulsion,wherein the fluid mobility modifier causes the treatment fluid to adopt a second surface tension that is less than the first surface tension; and introducing the treatment fluid into a subterranean formation.
