Trip safer and faster in closed-loop drilling operations
The only technology of its kind in the industry, our DDV® downhole deployment valve gives you a no-snub, no-kill alternative to conventional tripping techniques. In closed-loop drilling operations, such as managed pressure drilling and underbalanced drilling, the DDV system helps you to increase tripping speeds, enhance personnel safety, and minimize formation damage. It also provides an added measure of security when pipe is not in the hole.
The system features a flapper-type seal mechanism that contains reservoir fluids in the casing to prevent pressure at the surface. When the flapper is in the open position, the system allows full-bore passage for the drill bit.
