| 20100300684 | CONTINUOUS DOWNHOLE SCALE MONITORING AND INHIBITION SYSTEM - A technique facilitates monitoring of conditions which are prone to cause scale precipitation around downhole equipment. The technique also enables a local, downhole reaction to the potential for precipitation of scale. A downhole scale monitoring and inhibition system may be provided with a measurement module and injection module. The measurement module monitors at least one downhole parameter indicative of the potential for scale formation. In response to data output from the measurement module, the injection module is operated to provide downhole, local injections of an inhibitor chemical. | 12-02-2010 |
| 20100307757 | AQUEOUS SOLUTION FOR CONTROLLING BACTERIA IN THE WATER USED FOR FRACTURING - 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 diacetate; 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 diacetate 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. | 12-09-2010 |
