Wintershall’s goal

Wintershall expected that the challenging interval would require multiple bit runs to drill through halite, anhydrite, polyhalite, dolomitic limestone, and claystone.

What was tried first

The closest offset well, drilled in 2019, required three 8½-in drillbit runs to drill the entire section over 11 days.

The HyperBlade bit drilled a directional development well in The Netherlands in one run after the operator had expected multiple runs.

What Schlumberger recommended

The DBOS drillbit optimization system for aiding operators in selecting optimal bits recommended the HyperBlade bit for its precision-molded diamond table with an armored cutting edge for greater durability and control. Its chip-breaking profile and hyperbolic shape improve cuttings removal.

What was achieved

Using the DBOS system to aid in bit selection, Wintershall anticipated that multiple bit runs would typically be required from shoe to total depth. The HyperBlade bit drilled from shoe to TD in 5 days in one run.
