Abstract
Treatment fluids comprising degradable diverting agents and methods of using such treatment fluids in subterranean formations are provided. Examples of methods include methods of fracturing a subterranean formation. Another example of a method is a method of enhancing production from multiple regions of a subterranean formation penetrated by a well bore during a single trip through the well bore.
Claims20
A method of fracturing a subterranean formation, comprising:
- providing a fracturing fluid comprising a degradable diverting agent;
- introducing the fracturing fluid into a subterranean formation at a pressure sufficient to create or enhance at least one fracture therein;
- and
- permitting the degradable diverting agent to degrade.
A method of fracturing a subterranean formation comprising:
- positioning a hydrojetting tool having at least one fluid jet forming nozzle in a portion of the subterranean formation to be fractured;
- jetting a fracturing fluid comprising a degradable diverting agent through the at least one fluid jet forming nozzle against the formation at a pressure sufficient to form a cavity in the formation;
- further jetting the fracturing fluid through the nozzle to create or enhance at least one fracture in the formation;
- and
- permitting the degradable diverting agent to degrade.
A method of enhancing production from multiple regions of a subterranean formation penetrated by a well bore during a single trip through the well bore, comprising:
- positioning a hydrojetting tool having at least one fluid jet forming nozzle in a region of the subterranean formation to be fractured;
- jetting a fluid through the at least one fluid jet forming nozzle against the formation at a pressure sufficient to create at least one fracture in the formation;
- pumping a fluid comprising a degradable diverting agent into an annulus between the hydrojetting tool and the formation at a rate sufficient to raise the annular pressure to a level sufficient to extend the fracture into the formation;
- repositioning the hydrojetting tool in a different region of the formation;
- repeating jetting a fluid through the at least one fluid jet forming nozzle against the formation at a pressure sufficient to create at least one fracture in the formation and pumping a fluid comprising a degradable diverting agent into the annulus between the hydrojetting tool and the formation at a rate sufficient to raise the annular pressure to a level sufficient to extend the fracture into the formation;
- and
- permitting the degradable diverting agent to degrade.
