DENVER - Schlumberger announced a service milestone for its HiWAY* flow-channel hydraulic fracturing service. Since its release a year ago, HiWAY has been pumped in nearly 3,000 stages in vertical and horizontal wells in eight countries for more than 30 operators. "With respect to conventional fracturing methods, the HiWAY service provides improved production and ultimate oil and gas recovery, as well as higher reliability for proppant placement, reduced footprint and increased efficiency," said Dominique Malard, president, Schlumberger Well Services. "With applications in both horizontal and vertical completions, operators can take full advantage of the improved production and recovery in a wide variety of reservoirs and completion types." In the Eagle Ford Shale, South Texas, one operator sought a solution to improve oil and gas production and operational efficiency in a horizontal well. Issues related to the efficient conveyance of bulk materials, such as slick-water treatments that require millions of gallons of water and millions of pounds of proppant per well, posed additional challenges. The operator applied the HiWAY flow-channel fracturing service to address these challenges. The service increased 60-day cumulative oil production by 43% and 60-day cumulative gas production by 61%. Water and proppant consumption were both reduced by 58% and 35% per well, respectively. The service has been used in horizontal applications in the United States, Canada, Russia, Mexico and Argentina. The HiWAY service can be used for applications such as consolidated rock fracturing treatments, single and multistage oil and gas wells and formation temperatures from 38 to 149 degC [100 to 300 degF].
