Abstract:
A method of treating a portion of a well comprising: forming a treatment fluid, wherein the treatment fluid comprises: (A) water; and (B) a surfactant, wherein the surfactant is environmentally-friendly, and wherein the surfactant causes a liquid hydrocarbon to become soluble in the treatment fluid; and introducing the treatment fluid into the well, wherein the treatment fluid comes in contact with wellbore particles after introduction into the well, wherein at least a portion of the wellbore particles are coated with the liquid hydrocarbon prior to contact with the treatment fluid.
Abstract:
Methods treating a subterranean formation including providing a one-step acidizing treatment fluid comprising a first aqueous base fluid, a formation stimulation agent, and a stabilizing emulsion, wherein the stabilizing emulsion is an aqueous external emulsion comprising a second aqueous base fluid, a surfactant, and an aqueous-based surface modification agent; introducing the one-step acidizing treatment fluid into the subterranean formation; contacting the formation stimulation agent with the subterranean formation so as to acidize the subterranean formation and create conductive channels therethrough; and contacting the stabilizing emulsion with the subterranean formation so as to release the aqueous-based surface modification agent and stabilize unconsolidated formation particulates therein.
Abstract:
Methods including introducing a first treatment fluid comprising a first aqueous base fluid and a chelating etching agent into a low-permeability subterranean formation comprising carbonate material having a first fracture network at a first treatment interval therein, wherein the first fracture network comprises a first main fracture and a first microfracture. The method further comprises placing the chelating etching agent in the first fracture network and reacting it with the carbonate material in the first fracture network. In certain embodiments, the reacting removes the carbonate material, thereby creating at least one conductive channel on a face of the first fracture network. The method further comprises introducing a second treatment fluid comprising a second aqueous base fluid and micro-sized proppant particulates into the low-permeability subterranean formation and placing the micro-sized proppant particulates into the first fracture network to form a partial monolayer in the first microfracture.
