Kymera XTreme Hybrid Bit More Than Doubled ROP, Saved 2.5 Days

Location: Middle East

An operator working in a prolific field in the Middle East wanted to streamline and expedite development of the field. The operator typically drilled challenging interbedded sections using tungsten carbide insert (TCI) roller cone bits with an average ROP of approximately 38 ft/hr (11.5 m/hr), but believed it was possible to drill faster, mitigate torque fluctuations, and improve their cost-per-foot.

Baker Hughes recommended the Kymera™ XTreme (XT) hybrid drill bit for the application. Building upon the success of prior hybrid technology, the Kymera XT bit can be customized for each scenario and delivers smooth, reliable, faster, and more durable drilling performance in both vertical and curve drilling applications. It also delivers superior tool-face control in difficult drilling environments including challenging carbonates and interbedded formations where drilling speed and durability are often pushed to their limits. The Baker Hughes DART™ drilling application review team analyzed the formation properties through the difficult section and then customized a Kymera XT bit to perform optimally through that section. The BHA was also modeled and customized to achieve high performance and improved torque response with the Kymera XT bit. The DART team then performed a detailed formation drilling analysis to forecast how drilling performance would be affected by the Kymera XT hybrid drill bit.
