Abstract
In some aspects, the present disclosure includes systems and methods for determining and delivering diverting material to dominant fractures in a stage of a subterranean formation. The method includes creating or extending a plurality of fractures in a stage of a subterranean formation; pumping fracturing fluid to the plurality of fractures; identifying dominant fractures among the plurality of fractures; determining a desired amount of diverters to deliver to the dominant fractures; and pumping the determined amount of diverters to the dominant fractures so as to redistribute the flow of fracturing fluid between the plurality of fractures.
Claims18
A method for fracturing a stage of a subterranean formation, comprising:
- (a) creating or extending a plurality of fractures in the subterranean formation;
- (b) pumping fracturing fluid into the plurality of fractures;
- (c) identifying dominant fractures among the plurality of fractures by measuring the flow rate of the fracturing fluid using fiber optics, measuring fracture growth of the plurality of fractures, or any combination thereof;
- (d) determining a desired amount of diverters to deliver to the dominant fractures based, at least in part, on a model, historical data, real-time data, or any combination thereof;
- and
- (e) delivering the determined amount of diverters to the dominant fractures so as to redistribute the flow of fracturing fluid between the plurality of fractures.
A system for creating or extending a plurality of fractures in a stage of a subterranean formation, comprising:
- (a) a pump operable:
- (i) to deliver fracturing fluid into the subterranean formation to create or extend the plurality of fractures, and
- (ii) to deliver a plurality of diverters into one or more of the plurality of fractures;
- (b) at least one processor;
- and
- (c) a memory including non-transitory executable instructions that, when executed, cause the at least one processor to:
- (i) identify dominant fractures among the plurality of fractures by measuring the flow rate of the fracturing fluid, measuring fracture growth of the plurality of fractures, or any combination thereof, and
- (ii) determine a desired amount of diverters to deliver to the dominant fractures that will redistribute the flow of fracturing fluid into the plurality of fractures based, at least in part, on a model, historical data, real-time data, or any combination thereof.
A non-transitory computer-readable medium storing instructions that, when executed by at least one processor, performs operations comprising:
- (a) identifying dominant fractures among a plurality of fractures in a stage of a subterranean formation by measuring the flow rate of the fracturing fluid using fiber optics, measuring fracture growth of the plurality of fractures, or any combination thereof;
- and
- (b) determining a desired amount of diverters to deliver to the dominant fractures that will redistribute the flow of fracturing fluid into the plurality of fractures based, at least in part, on a model, historical data, real-time data, or any combination thereof.
