Churchill Drilling Tools celebrates deployment of DAV at record depth
Churchill Drilling Tools has announced the deployment of its dart-activated DAV MX circulating valve at a record measured depth of 26,012 ft.
HOUSTON –Churchill Drilling Tools has announced the deployment of its dart-activated DAV MX circulating valve at a record measured depth of 26,012 ft.
Churchill’s DAV MX and its Smart Dart activation technology were deployed at the record depth in a development well off Louisiana in the Gulf of Mexico. Enabling rapid and assured reamer bypass in a sidetrack operation, the application exploited the deepwater capability of the Smart Dart to withstand both rapid delivery speeds and high temperature and pressure variations.
The company says that using its multi-cycle capability, bypass deactivation was equally simple and assured as the assembly was pulled from hole. This proved the capability of the system to give the operator total control over both the fluid path directions and the drilling equipment while maintaining the well control flow-rate objectives set out in the program.
The system’s previous record deployment exceeded 16,000 ft in a well West of Shetland. The high profile achievement is the latest to be delivered out of Churchill’s recently opened Houston base, where the full suite of Churchill products and services is now available.
