Abstract
Systems and methods having friction reducer compositions for use in subterranean treatment fluids are provided. An embodiment of the present disclosure is a method comprising: (A) forming a treatment fluid comprising: an aqueous base fluid, a friction reducer, and an alkaline buffering agent, wherein the treatment fluid has a pH in the range of about 7 to about 10; and (B) injecting the treatment fluid into a wellbore penetrating at least a portion of a subterranean formation at a pressure sufficient to create or enhance one or more fractures within the subterranean formation.

A method comprising:
- (A) providing a treatment fluid comprising:
- an aqueous base fluid,
- a friction reducer, and
- an alkaline buffering agent,
- wherein the treatment fluid has a pH in the range of about 7 to about 10;
- and
- (B) injecting the treatment fluid into a wellbore penetrating at least a portion of a subterranean formation at a pressure sufficient to create or enhance one or more fractures within the subterranean formation.
A method comprising:
- (A) providing a treatment fluid emulsion comprising:
- an external phase that comprises an aqueous base fluid,
- a friction reducer,
- an alkaline buffering agent comprising a surfactant, and
- an internal oil phase,
- wherein the external phase of the treatment fluid emulsion has a pH in the range of about 7 to about 10;
- and
- (B) injecting the treatment fluid emulsion into a wellbore penetrating at least a portion of a subterranean formation at a pressure sufficient to create or enhance one or more fractures within the subterranean formation.
A composition comprising:
- an aqueous base fluid,
- a friction reducer, and
- an alkaline buffering agent comprising a salt selected from the group consisting of:
- a bicarbonate salt, a carbonate salt, sodium hydroxide, potassium hydroxide, a chelating agent, a surfactant, and any combination thereof,
- wherein the composition has a pH in the range of about 7 to about 10.
