摘要： The invention discloses method of treatment and reuse of oilfield produced water. The method comprises: providing an aqueous medium comprised at least in part of oilfield produced water; contacting the aqueous medium with a zirconium compound; whereby the fluid viscosity and/or fluid drag reduction ability of the combination of the aqueous medium and zirconium compound is improved compared to the aqueous medium alone; introducing the combination in to the well; and allowing the combination to contact the formation. In another embodiment, the aqueous medium is further contacted by a friction-reduction additive. Still in another embodiment, the aqueous medium is further contacted by a gelling additive. Still in another embodiment, the fluid is energized with a gas.

摘要： A subterranean formation stimulation method utilizes a treatment fluid comprising residual drilling fluid injected into the formation, and producing the stimulated formation. In one embodiment, there is provided a method, comprising fracturing a tight gas formation wherein a treatment fluid comprising residual drilling fluid is injected into the formation to form a fracture with a consolidated proppant pack having a relatively higher conductivity than the formation, wherein the fracturing step comprises injection of treatment fluid in stages comprising a residual drilling fluid-rich treatment fluid stage and a residual drilling fluid-lean treatment fluid stage; producing gas, gas condensate or a combination thereof from the formation through the fracture and into a production conduit in fluid communication therewith.

摘要： A well treatment microemulsion for use in a subterranean formation is disclosed, the microemulsion comprises a solvent blend comprising a solvent and a co-solvent; a surfactant blend comprising a surfactant, wherein the surfactant blend is able to give formation intermediate wettability properties; an alcohol; and a carrier fluid; wherein the alcohol, the solvent and sur-factant blends are combined with the carrier fluid to produce the well treatment microemulsion. By intermediate wettability it is meant that the water has an advancing contact angle on the surface between 62 and 133 degrees. The associate method of treating a subterranean formation of a well with the microemulsion and the associate method of modifying the wettability of the formation with the microemulsion are also disclosed.

摘要： Methods and apparatus of embodiments of the invention relate to a system for treating a subterranean formation including mixing equipment to form a fluid comprising sodium hypochlorite and sodium diacetate; and pumps and a tubular to introduce the fluid into the subterranean formation, wherein a surface of the subterranean formation contains at least 15 percent less microorganisms than if no sodium hypochlorite were in the fluid. Methods and apparatus of embodiments of the invention relate to a method of producing a petroleum product from a wellbore including using a well treatment system comprising mixing equipment, pumps, and a tubular, forming a fluid comprising sodium hypochlorite and sodium acetate; and introducing the fluid to the well treatment system to achieve a reduced population of microorganisms in the system. Methods and apparatus of embodiments of the invention relate to a system, comprising: a subterranean formation, a well treatment apparatus comprising mixing equipment, pumps, and a tubular, and a fluid comprising sodium hypochlorite and sodium acetate to achieve a reduced population of microorganisms in the system. Methods and apparatus of embodiments of the invention relate to a method for treating a subterranean formation, comprising forming a fluid comprising sodium hypochlorite, a buffer, and a polymer; introducing the fluid to a surface of a subterranean formation; and decreasing a population of microorganisms, wherein the surface of the subterranean formation contains at least 15 percent less microorganisms than if no sodium hypochlorite were in the fluid, and wherein the fluid exhibits a pH of about 4.0 to about 7.5. Methods and apparatus of embodiments of the invention relate to a method for treating a subterranean formation, comprising forming a fluid comprising sodium hypochlorite and sodium diacetate; and introducing the fluid to a subterranean formation, wherein forming the fluid does not include introducing an acid, and wherein forming the fluid does not include forming a precipitate.
