Our ACD system is the industry’s first active, non-rotating sealing device for MPD operations. The ACD seals the wellbore annulus and diverts returns using a novel, actively energized sealing element controlled by our industry-standard annular packer system. The design allows the system to determine the sealing element condition, while an external sealing element control contains high-pressure wellbore fluids even after the sealing element reaches a worn state. The ACD eliminates complex bearing assemblies and high-wear rotary seal components found in conventional passive rotating control devices (RCD) that are the source of many MPD problems. Monitoring and controlling the seal reduces maintenance, extends service life, and enhances safety. Our Active Control Device (ACD), developed specifically for deepwater service, is a fundamental advance in annular pressure containment that eliminates passive rotating control device (RCD) design deficiencies. The ACD’s pioneering MPD capabilities can dramatically reduce costs, eliminate common operational problems, and improve reliability and safety.

According to client preferences, the ACD can interface directly with OEM riser equipment to provide functionality without the need for handling accessories to manage the running and retrieval of the joint. For rig fleets using a common riser type, this also allows for easy movement of the ACD between rigs to support MPD projects.

Our Drill String Isolation Tool (DSIT) is an industry-leading riser annular packer that fits a variety of purposes. As the backbone of most existing riser gas handling (RGH) systems in the field, the DSIT enables the rig to quickly close the riser below the termination joint, allowing gas in the riser to be circulated out safely and efficiently. As a key fixture in many MPD specialty joint systems, the DSIT serves as a secondary sealing system when changing an ACD or RCD seal element assembly, as well as providing RGH capabilities during non-MPD hole sections.

Our flow spool is a common component in many MPD and RGH specialty joint systems. It serves as a conduit for drilling returns to exit the riser below an ACD, RCD and provides dual outlets and redundant subsea shut-off valves. This functionality diverts drilling fluids, cuttings, and gas safely away from the drill floor while the annulus above it is isolated. The flow spool enables various MPD operations, including applied surface backpressure drilling, pressurized mud cap drilling, and riser gas handling.

Deepwater drilling operations present many different needs and requirements–a one-size-fits-all approach is difficult to apply. That’s why our MPD systems are offered in multiple configurations to allow integration with the rig in a way the makes the most sense for the client.

Our unitized MPD specialty joint integrates our ACD, DSIT, and flow spool functionality in a single compact and lightweight joint. The approach provides the entire spectrum of MPD specialty joint functionalities while minimizing handling constraints when running and retrieving the riser.

The Compact Riser Gas Handling (RGH) system permanently integrates DSIT and flow spool functions in a single joint to remove connections and reduce weight. The compact RGH may interface with our riser flanges or directly with OEM riser equipment as the client determines. Installation of a riser gas handling system improves safety and kick response options while making the rig MPD ready.
