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. .
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. .
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 and RCD and provides. .
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. .
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.
[pdf] Drilling in deep waters can be performed by two main types of mobile deepwater drilling rigs: drilling rigs and . Drilling can also be performed from a fixed-position installation such as a fixed platform, or a floating platform, such as a , a , or a semi-submersible production platform. 1. Fixed Platform – A Fixed Platform consists of a tall, (usually) steel structure that supports a de.
