摘要： A system includes a wellbore intersecting a subterranean formation and a treatment flowpath disposed in the wellbore including a fluid path from a surface location to the subterranean formation and returning to the surface location. The treatment flowpath has a delivery flowpath upstream of the subterranean formation and a pertinent flowpath at and downstream of the subterranean formation. The system further includes a gravel pack assembly having a first crossover port fluidly coupling the delivery flowpath to the pertinent flowpath, a screen, a washpipe, and a second crossover port fluidly coupling the washpipe to a return portion of the pertinent flowpath. The system further includes a friction reducing agent that is effective in at least part of the pertinent flowpath, but that is not a friction reducer in solution in the treatment fluid at the surface location.

摘要： A method of introducing friction reducing agents within a wellbore penetrating a subterranean formation during a gravel packing operation is accomplished by providing a length of tubing located downhole within the wellbore for conducting fluids within the wellbore through the tubing during circulating of gravel packing fluids introduced from the surface within the wellbore. At least a portion of the tubing is surrounded by a screen for screening out particulate matter during the gravel packing operation. An annular space is defined between an interior of the screen and the exterior of the tubing. A friction reducing agent is dispensed from a dispensing apparatus that locates downhole with the tubing. The dispensing apparatus includes a housing and a chamber disposed within the housing that has one or more outlets that open into the annular space defined by the screen and tubing for dispensing the friction reducing agent. The dispensing apparatus further includes a piston and a trigger mechanism for actuating the piston. When the trigger mechanism is activated to actuate the piston, the friction reducing agent is dispensed through the one or more outlets at a position downhole remote from the surface during the circulating.

摘要： A method of treating a subterranean formation penetrated by a wellbore is carried out by preparing a treatment fluid at a surface location based upon an initial model of fluid properties for the treatment fluid. The treatment fluid is formed from a first fluid stream and at least one additive fluid stream that are combined to form a treatment fluid stream that is introduced into the wellbore in a substantially continuous process. A fluid property of at least one of the streams is monitored while forming the treatment fluid to provide at least one monitored fluid property of the at least one of the streams. The model is updated based upon the at least one monitored fluid property during the substantially continuous process. Optionally, at least one of the first fluid stream and the at least one additive stream is adjusted as necessary based upon the updated model.

摘要： Compositions and methods are given for delayed breaking of viscoelastic surfactant gels inside formation pores, particularly for use in hydraulic fracturing. Breaking inside formation pores is accomplished without mechanical intervention or use of a second fluid. Bromate oxidizing agents are used along with selected breaking activators for the bromate breaking compounds. Useful bromate breaking activators include acid-generating breaking activators, oxidizing sulfur containing breaking activators, and reducing agent breaking activators.
