Drilling Spool

Drilling Spool

A Drilling Spool is a pressure-containing wellhead component installed between Blowout Preventers (BOPs), casing heads, or other well control equipment. It provides additional spacing for the installation of valves, choke and kill lines, and other pressure-control accessories while maintaining well integrity during drilling, completion, workover, and intervention operations. Drilling spools are manufactured to stringent API standards to withstand high-pressure and high-temperature (HPHT) environments.

Our Drilling Spools are available for sale and lease, providing reliable well control solutions for onshore and offshore oil and gas operations.
