Churchill Drilling Tools, provider of systems for the drilling and completions markets, has announced the deployment of its dart-activated DAV MX circulating valve at a record measured depth of 26,012 ft. The achievement was delivered out of Churchill’s recently-opened Houston base.
Churchill’s DAV MX and its Smart Dart activation technology were deployed in a development well off Louisiana in the Gulf of Mexico. The application exploited the deepwater capability of the Smart Dart to withstand both rapid delivery speeds and high temperature and pressure variations.
The system’s previous record deployment exceeded 16,000 ft. in a well West of Shetland.
The DAV MX is used globally across a range of drilling environments including deepwater, high-pressure, high-temperature (HPHT) and high-angle extended reach drilling. The Mechanical Extrusion system is significantly more reliable, faster and more cost-effective than polymer extrusion, the process used for traditional ball-activated systems.
Churchill Drilling Tools’ director Mike Churchill said: “Our technology is now well proven and this latest result confirms that we haven’t yet approached the limit of the system’s capabilities. It’s also extremely rewarding that the new Houston team, who have worked so hard to set up operations, have hit the ground running and come out with a record so quickly.”
