Developed in close collaboration with the Japanese National Oil Company, Halliburton Sperry-Sun's GeoPilot second-generation 3D rotary steerable system was awarded the BG Group Chief Executive Technology Innovation Award for its work on BG's Blake Field in the North Sea.
"BG is delighted to be presenting this award to Halliburton Sperry-Sun for their innovative drilling tool. The Geo-Pilot system has made a major impact on our work on the Blake Field, saving us time and money and providing us with significantly improved drilling efficiency," said Derek Hudson, BG Group vice president, North Sea (NSW).
Sperry-Sun said the Geo-Pilot system allows rotation of the drillstring while steering the wellpath to the desired location. "It not only extends the length of reservoir sections but also places the wellbore in the optimum position, thus enhancing production while minimising gas coning and water production," the company said.
Sperry-Sun said the drill tool helped BG secure operational savings of $US3.2 million over five wells, rig time savings estimated at 37 days, and vastly improved drilling efficiency - 1.4 days per 305m of horizontal section, compared with 3.6 days using conventional technology.
