E&P Plus Tech Trends: New drilling and completions technologies

As companies look toward market recovery, these new drilling and completions technologies will help producers boost efficiencies and streamline operations

Drill bit with concave-shaped cutting elements reduces drilling costs

Smith Bits, a Schlumberger company, has released the StrataBlade concave diamond element bit, which is designed to improve the ROP in a wide range of rock types while withstanding impact damage often associated with drilling interbedded formations. The StrataBlade bit incorporates new geometry Strata concave diamond elements across the bit face, which increases cutting efficiency and results in higher instantaneous ROP with the same operating parameters. In deep lateral wells where weight transfer to the bit is a challenge, the StrataBlade bit drills with higher ROP when compared with traditional PDC bits with flat cutters. Improved cutting efficiency also means a better torque response at the bit for conformance to directional plans. The bit has undergone field testing in North America, specifically in the Haynesville and the Appalachian Basin. In the East Texas Travis Peak and Cotton Valley formations, the StrataBlade bit enabled an operator to eliminate two bit runs while drilling to 10,000-ft measured depth with an average ROP increase of 28% compared to direct offset wells.
