Abstract
Methods and compositions that include a method comprising: providing a treatment fluid comprising at least a plurality of degradable diverting agents that comprise at least one degradable material selected from the group consisting of a fatty alcohol, a fatty acid salt, a fatty ester, a proteinous material, and a combination thereof; and introducing the treatment fluid into a subterranean formation during a subterranean operation via a well bore.
Claims20
A method comprising:
- providing a treatment fluid comprising at least a plurality of degradable diverting agents that comprise at least one degradable material selected from the group consisting of a fatty alcohol, a fatty acid salt, a fatty ester, a proteinous material, and a combination thereof;
- and
- introducing the treatment fluid into a subterranean formation during a subterranean operation via a well bore.
A method comprising:
- providing a drilling fluid comprising at least a plurality of degradable diverting agents that comprise at least one degradable material selected from the group consisting of a fatty alcohol, a fatty acid salt, a fatty ester, a proteinous material, and a combination thereof;
- and
- drilling a well bore in a subterranean formation in an operation involving the drilling fluid.
A method comprising:
- providing a fracturing fluid comprising at least a plurality of degradable diverting agents that comprise at least one degradable material selected from the group consisting of a fatty alcohol, a fatty acid salt, a fatty ester, a proteinous material, and a combination thereof;
- and
- placing the fracturing fluid comprising the diverting agent at a pressure sufficient to create or enhance a fracture in a portion of the formation.
A method comprising:
- providing a treatment fluid comprising at least a plurality of degradable diverting agents that comprise at least one degradable material selected from the group consisting of a fatty alcohol, a fatty acid salt, a fatty ester, a proteinous material, and a combination thereof;
- introducing the treatment fluid into a subterranean formation during a subterranean operation via a well bore;
- allowing the degradable diverting agent to divert the flow of at least a portion of a second treatment fluid comprising an acid from a first location within the well bore to a second location within the well bore;
- and
- allowing the acid to interact with a portion of the formation to form an acidized portion of the formation.
