Annular BOP Systems

Annular BOP Systems

Hold up to everyday challenges

When operating oil flow in a rugged environment, you need reliable technology that can perform under pressure. Annular BOPs (ABOPs) are a critical component of onshore and offshore exploration. They provide a pressure barrier by sealing around tubular goods, like drill pipes, during drilling operations to ensure optimal safety whenever a problem arises.

Original design, trusted results

  • When operating oil flow in a rugged environment, you need reliable technology that can perform under pressure. Annular BOPs (ABOPs) are a critical component of onshore and offshore exploration. They provide a pressure barrier by sealing around tubular goods, like drill pipes, during drilling operations to ensure optimal safety whenever a problem arises.


    Our ABOPs feature only two moving parts, the hydraulic piston, and packing unit—reducing component wear. A replaceable packing unit wear plate eliminates metal-to-metal contact, extending time being overhaul and repair intervals. Get reliable and tested performance with the elastomer compound design of ABOPs.

    Drilling contractors have called the GX™ AnnularBOP "the best annular in the business” for one reason: exceptional performance and uptime. Its single packing unit has provided continuous service for as long as a year, and it has continued to hold pressure after exposure to extreme temperatures and extensive stripping. The GX can strip and seal on all pipe sizes and achieve complete shutoff. In the field and in laboratory tests.

    Our ABOPs offer proven exceptional performance, longer uptime, and extended service intervals. Thanks to a configuration designed from the start for ease of maintenance and operation, drilling projects can remain online and on budget.

    Additionally, our ABOPs have a number of advantages including: 

    • Unparalleled resistance to extreme pressure and temperature
    • Reduced wear and tear due to simple, yet effective design
    • Driller’s choice of ABOP since 1948
    • Inspection, overhaul, repair, and recertification services for all ABOP products available
