SCOOP/STACK: TECHNOLOGY 30 | September 2017 | hartenergy.com "We want to recycle and reuse all we can," Durfey said. "There could always be plant No. 2. We've started to work together with some of our peers on how we could share recycling resources and infra- structure to make our combined assets work for the industry to get a better bang for our buck." Frack management and workflow efficiencies The rush of activity in Oklahoma caused by esca- lating delineation work on oil fields in the state's Scoop/Stack regions has put pressure on service providers to effectively and safely ramp up fol- lowing one of the most prolonged and damaging industry downturns in history. Idle iron is being reinvigorated and put back to work. Service com- panies are hiring hands in the region. The Mid- continent has seen rig activity more than double year-over-year, and the scramble is on to drill and complete these prolific oil wells. Halliburton has a raft of specialty offerings to support both the frac- turing process subsurface and improved efficiencies aboveground, enabling it to deliver these higher rate wells faster than ever before. Using its AccessFrac service for near-wellbore diversion, Halliburton is able to improve cluster efficiency when conducting multistage treatments. "Some operators might have three perforation clusters, others may have four, five, up to seven clusters in a stage," said Mark Parker, Halliburton's technology manager for the Midcontinent. "Our near-wellbore AccessFrac service allows us to effec- tively treat all perf clusters. In some cases without diversion a couple of primary fractures would be developed, but you wouldn't see any others devel- oped in the stage. So even though you desired five fractures created, you might only get two. These diversion products increase cluster efficiency to create the designed fractures in the near wellbore." There is also a component to complexity in the reservoirs. In the far field, when fractures are being created and extending into the reservoir, additional AccessFrac products divert and create complexity in the far field away from the wellbore. "That has been a real benefit to operators as far as increasing production and getting these high pro- ductivity rates," Parker said. "We think it helps with the near-term productivity, the IP rates, but also on the ultimate recovery of the reservoirs—increasing the EURs in these unconventional plays." Another tech leader in the region is Hallibur- ton's MicroScout service. Halliburton's AccessFrac technology keeps well fractures open and flowing. (Image courtesy of Halliburton)
