Our design process isn't about cookie-cutter solutions. #weknowrock and that’s where we start—with the kind of formation and lithology your bit will encounter. Working backward from the rock-cutter interface, analysis continues upward along the entire drillstring of individual components and the total system on bit behavior in a dynamic drilling environment. What this ultimately yields is the bit you need that #eatsrock4breakfast.

Blade bits have a history of record-breaking performance

We hold 53% of global drillbit records, and we set over 50% of the records in the most recent Hart Energy E&P drillbit review. Read these case studies for details on how different Blade bits helped operators by delivering faster ROP, more footage, and fewer drilling days.

Blade family bits are unique because we begin the design process by asking one crucial question: “What best improves bit performance in specific situations?” This approach led to our creating the first bits in the Blade family, using elements with specialized 3D shapes to optimize performance well beyond conventional fixed and flat cutters. The immediate benefit was reduced wear that meant fewer bit trips, which lowered NPT and costs.

But this is really just the tip of the iceberg. We are advancing better bit performance every day because of our continuing work to understand customers' drilling challenges, and answering those challenges with something not quite as small as it seems—cutting elements. Cutting elements are small, but their effect is huge. In fact, that’s how Schlumberger reshaped cutting performance—by studying the behavior of cutting elements in key drilling applications.

The result is two classes of innovative cutters—the rolling cutting element and the 3D cutting element. Each possesses proprietary characteristics developed for specific applications and is the basis for each bit in our Blade family.
