AFGlobal is an oil and gas OEM and technology specialist providing differentiated technology, products, and services to the upstream sector. Our strategic technologies include our advanced drilling systems, pressure pumping technologies, lifecycle services and subsea production systems. We are the market-leading designer and manufacturer of managed pressure drilling systems, and we have a significant global market position in pressure pumping, subsea connections, as well as sealing products for land, offshore and general industrial applications. We also offer energy solutions for sustainable, cost-effective manufacturing capabilities across the upstream and downstream sectors. 

At this year's OTC, we will showcase our MPD Active Control Device (ACD) and other key offshore technologies in space 938, and our proprietary DuraStim pump will be featured outside in our space 10715.  Visit us at for more information.




  • Active Control Device
    AFGlobal’s purpose-built ACD provides the prerequisite seal and diversion of annular wellbore returns using a non-rotating device enabled by active pressure.

  • The ACD's unique sleeve is a co-molded element comprised of an enhanced urethane matrix reinforced with a durable polytetrafluoroethylene (PTFE) inner shell. As the sealing sleeve wears, pressure is actively applied to force the element against the drill pipe to maintain consistent seal performance. The device varies hydraulic pressure on the seal to compensate for wear and accommodate passage of wear-inducing tool joints. RCDs do not have the ability to be adjusted in-situ to prolong seal integrity. Service life and performance of the ACD is further enhanced by the greater durability of the co-molded element and lubrication of the seal with clean drilling mud. Active pressure sealing is a significant advance over MPD operations that degrade the performance of passive RCD elastomer seals. The device varies hydraulic pressure on the seal to compensate for wear and accommodate passage of wear inducing tool joints. The active seal results in a stripping capacity that exceeds conventional RCD sealing elements. The adjustable active pressure system uses field-proven BOP technology—no bearing or wear sleeve required, ultimately offering repeatable performance.
