Surface modification agents may be included in emulsified acidic treatment fluids to leave surfaces in carbonate formations water wet after acidizing operations. A method of acidizing a subterranean formation, comprising: providing a treatment fluid in the form of an invert emulsion, wherein the treatment fluid comprises: a hydrocarbon phase comprising an oil-soluble liquid and an emulsifier; and an aqueous acidic phase comprising water, an acid, and a surface modification agent; and introducing the treatment fluid into a wellbore.

Emulsified acidic treatment fluid with surface modification agents

Methods including pumping a fracturing fluid into a subterranean formation through an annulus between the subterranean formation and a pipe conveyance at a rate above a fracture gradient of the subterranean formation to create and/or open at least one fracture in the subterranean formation; continuously pumping a proppant-free fluid into the subterranean formation through the annulus at a first rate to extend the open fracture; continuously pumping a proppant fluid through an interior of the pipe conveyance and out the exit of the interior of the pipe conveyance at a second rate that is less than the first rate; and placing the proppant particulates into a portion of a fracture in the subterranean formation so as to form a proppant pack having proppant-free channels therein.
