PERMIAN BASIN: TECHNOLOGY 42 | November 2017 | F rom the drill bit to the perf gun through the pump and into the flowline, technology is making its mark in the Permian Basin. Service companies are stepping forward with better sci- ence, engineering and data management. They have each created breakthroughs—and a few twists on old tech—to reduce costs while drilling better boreholes and zeroing in on pay zones. Fewer walking bits, better completions By many accounts, the Baker Hughes-GE Oil & Gas marriage is already creating innovation. "We've introduced multiple technologies in the last six to 12 months with significant results," said Paul Madero, Permian GeoMarket director for Baker Hughes, a GE company (BHGE). Madero helps manage all three of BHGE's Perm- ian operations: drilling, completion and production. "It is no secret the wells are getting deeper, with longer laterals and more stages," he said. "There's a strong desire for increased rate of penetration and efficiencies in general." In the past 12 months, BHGE has introduced its Dynamus platform, using StayTrue shaped diamond element technology in a polycrystalline diamond compact [PDC] bit. "It enhances the PDC bit, extending its life," Madero said. "It decreases lateral vibration by up to 90%. In a 2-mile lateral, these vibrations cause motor failure and bit wear." With the bit cutting instead of walking, Madero says lateral drilling rates have increased up to 50%. Madero believes a better, less-undulated well- bore is key to ideal completion and production. "A lot of these wells have been drilling conven- tionally," he said. "That gives you a lot of undu- lation on wellbore placement. Water production comes up all the time. A lot of water conversation starts with, 'Hey we're producing water, we need trucking, should we build infrastructure?' We think these conversations should start at the very beginning. Get the well placement down precisely, stay out of certain zones, such as fracking up into the Dean, or other water-driven formations that add to water production." Shifting from conventional to rotary steerable drilling systems, such as BHGE's AutoTrak, can add that precision, according to the company. "You can actually land your well where you want, enhance the production of hydrocarbons, and minimize the production of water through good lateral characterization and placing a better stim- ulation," Madero said. "We've directly correlated more undulation to less production and AutoTrak Curve enables maximum precision." The company that introduced the first rotary bit and rotary steerable is still innovating. "Our Kymera FSR directional hybrid drill bit product line has taken off," Madero said. This bit's job is to execute the correct curve. "You can build a beautiful lateral, continuous with minimal undulations," he said. "But if the curve is not set up correctly, you don't have a good entry point into the formation.
