Houston-based managed pressure drilling systems specialist Managed Pressure Operations International reports that it is expanding its delivery of the innovative Non-Stop Driller (NSD) continuous circulation system.

Devoloped to maintain constant bottom hole pressure and enabling continuous hole cleaning during connections, the NSD continuous circulation system is now being utilized in the US, Middle East, Asia and elsewhere to prevent wellbore ballooning, stuck pipe incidents and connection gas buildup, significantly reducing non-productive time.

The NSD sub, consisting of a ball valve and custom-designed, high-pressure side entry connection valve, can be rapidly prepared to accommodate all drilling pipe connection sizes and types in a wide range of applications, including: conventional overbalanced drilling; deepwater operations; extended reach drilling of long high angle or horizontal sections; HP/HT wells; air and foam drilling; MPD operations, and underbalanced drilling.

President and CEO Charles Orbell commented: ‘A recent series of contract awards from major operators is a significant step forward not only for Managed Pressure Operations, but for the industry as new enabling technologies like the Non-Stop Driller are recognized and deployed to improve drilling performance and well integrity.’
