摘要： Provided are treatment fluids that comprise an aqueous base fluid, and a methyl ester sulfonate surfactant, and associated diverting methods of use. In one embodiment, the present invention provides a method of treating a subterranean formation comprising: providing a treatment fluid comprising an aqueous base fluid, and a methyl ester sulfonate surfactant; introducing the treatment fluid into a portion of a subterranean formation; and allowing the treatment fluid to divert at least a portion of a second fluid to a different portion of the subterranean formation. Also provided are methods of diverting a fluid from a portion of a subterranean formation. In some instances, the treatment fluids exhibit viscoelastic behavior which may be due, at least in part, to the association of at least a portion of the methyl ester sulfonate surfactant into a plurality of micellar structures.

摘要： A method of increasing the fracture complexity in a treatment zone of a subterranean formation is provided. The subterranean formation is characterized by having a matrix permeability less than 1.0 microDarcy. The method includes the step of pumping one or more fracturing fluids into a far-field region of a treatment zone of the subterranean formation at a rate and pressure above the fracture pressure of the treatment zone. A first fracturing fluid of the one or more fracturing fluids includes a first solid particulate, wherein: (a) the first solid particulate includes a particle size distribution for bridging the pore throats of a proppant pack previously formed or to be formed in the treatment zone; and (b) the first solid particulate comprises a degradable material. In an embodiment, the first solid particulate is in an insufficient amount in the first fracturing fluid to increase the packed volume fraction of any region of the proppant pack to greater than 73%. Similar methods using stepwise fracturing fluids and remedial fracturing treatments are provided.
