Halliburton launches new intelligent drill bit

Halliburton has released Cerebro in-bit sensor package a new technology that improves data measurement and overall drilling performance.

The new service obtains performance data directly from the drill bit and analyses it to optimise cutter engagement, reduce uncertainty and increase drilling efficiency.

Cerebro provides an unprecedented view into an entire run by continuously capturing downhole vibration and motion data. This information helps operators pinpoint where bit damage occurred and when optimal performance is not achieved due to inconsistent design or operating parameters. The system identifies several common drill bit factors including lateral and axial vibration, torsional resistance, whirl and stick-slip which can negatively impact drilling speed and reliability.

“Cerebro further advances our communication with the drill bit by capturing data as close to the cutting structure as possible,” said Scott Regimbald, vice president of Drill Bits and Services. “By having a greater understanding of what is happening downhole, we can optimize bit design and performance to help operators drill more intervals in single runs.”

On a recent set of runs in the U.S. mid-continent, Cerebro acquired information that allowed the operator to utilise a more aggressive cutting structure to increase drilling efficiency and reduce well time. This data also showed that higher drilling speeds could be used in softer sections of the well without vibration limitations.
