PERMIAN BASIN: TECHNOLOGY 46 | November 2017 | hartenergy.com an enhanced rate of penetration and control. What you plan and what you execute are aligned. "In areas like the Delaware Basin we're able to improve drilling days up to 50% doing one run curve and laterals with AutoTrak Curve," Madero said. "Some operators are drilling first quartile wells, when many thought it would take a year to get there." Assuming that a near-perfect, barely undulating wellbore is in place, operators can tap other effi- ciencies during completion. BHGE has run field trials on a new way to handle plug and perf (PNP), with goals of using less water during completion and adding speed and safety to the process. "Over 90% of plug and perf uses a balldrop type composite plug where you set the plug, fire the guns, pull out, then deploy the ball from surface," Madero said. "Every time you drop one of those balls, you are displacing water, anywhere from 100 to 300 barrels," he said. "With our Ballista technology you are able to set the plug, fire the guns, activate a tool already in the string, then drop the ball right by the composite plug. It does not require you to displace excess fluid from surface." The procedure is a time-saver, which helps frack crews run more efficiently. "Depending on how you are set up, whether you are zipper fracking, you can see up to 20% to 25% increase in the number of stages you can complete in a day, ultimately turning your one-frack crew into a multiple-frack crew," Madero said. With more formations involved in water pro- duction and disposal creating greater drilling com- plexity resulting in lost circulation zones, BHGE has responded with improved liner hangers such as ControlSet Flex-Lock.
