Smith Bits

A Schlumberger company

Smith Bits has been a Schlumberger company since 2010. Like Herman C. Smith, our people are a curious sort—working to better understand drilling applications our customers encounter and how to improve drilling operations with reliable advancements that make a difference where the bit meets the rock.

Comprehensive drilling system analysis

Our design process isn't about cookie-cutter solutions. We start at the rock with the kind of formation and lithology you will encounter—working backward from the rock-cutter interface. Analysis continues upward along the drillstring, the drive system, individual BHA components, and the total system on bit behavior in a dynamic drilling environment. It also takes into account the specific operating parameters and the interaction between individual elements of the drilling assembly.

Not every well is exactly the same—even within a field. That's why we persist in having such a consistent and methodical process for delivering performance and improvements that make a difference. The outcome of this process are application-specific bits that consistently outperform previous designs or third-party bits when measured against the same parameters.
