The system, which has now chalked up more than 400 runs, has already established a strong reputation for reliability and performance in the exploration drilling arena over the years, but Churchill is seeing an increase in demand for the DAV MX™ from the development drilling and the plug and abandonment sectors.

Four main features have delivered these value benefits:

• Valve simplicity is made possible by enclosing all the “smart” parts inside the activating darts. The DAV MX™ contains simple tried and tested spring and sealing geometry, coupled with premium grade materials honed over more than 15 years’ of drilling applications. With large concentric through-bores and low-profile seating the design provides the best way to ensure downhole dormancy and capability for weeks at a time.
