Churchill Drilling Tools is celebrating the five-hundredth deployment of its DAV MX CircSub. The company, located in Houston and Aberdeen in the UK, has forged a sound reputation in the Gulf of Mexico, where its dart activation technology has been recognised for its versatility, capability and reliability in challenging environments.
The DAV MX has completed 500 runs in key production locations around the world within five years and in this time has set several new industry records. “Our technology is now well proven and is effectively changing the way the drilling industry conducts certain operations. The 500th run of the DAV MX in particular cured 400bbl/hour losses for an operator by allowing more than 400bbl of coarse lost circulation material through”, Churchill Drilling Tools’ Director Mike Churchill said.
The DAV MX is used globally across a range of drilling environments including deep water, HPHT and high-angle extended reach drilling. The Mechanical Extrusion (MX) system is significantly more reliable, faster and more cost effective than polymer extrusion, the process used for traditional ball-activated systems.
