Churchill addresses downhole issues offshore Norway

Offshore staff

ABERDEEN, UKChurchill Drilling Tools says new features in its DAV MX circulation sub are bringing Norwegian offshore operators performance and productivity gains.

The company has supplied its first sequential DAV MX configuration for both multi-position and multi-cycle hole cleaning and displacement bypass in a single string, providing sustained activation angles of up to 82° in sections of more than 4,000 ft (1,219 m).

In addition, the company’s HyPR Hole Saver is said to be safeguarding multiple Norwegian wells against stuck pipe cost overruns.

Another in-house development, the Ultra Series Dart, is allowing various Norwegian operators to activate faster while pushing the standard differential pressure operating envelope by up to 50%, Churchill claims.

Finally, the company says its Emergency Shut-Off Dart is providing the operators with a way of mitigating risk when they find themselves pushed outside the operating envelope due to difficult well conditions.
