Multitrim Drilling Chock

Multitrim Drilling Chock

The Cameron CAM30-DC multitrim drilling choke is a creative solution for choke-and-kill drilling manifold applications. It includes the long established gate-and-seat (G&S) drilling trim, but offers the versatility to switch between this and a variety of other trim styles, all within a single choke. The gate-and-seat trim can be easily replaced with the external floating sleeve (FS) trim for greater controllability and erosion resistance. This interchangeable choke also offers multiple actuation options, from manual handwheel to variable speed electric actuation. A common choke body across the Cameron CAM30 series of chokes ensures direct interchangeability. Managed pressure and dual-gradient drilling operations stand to gain from this advance because changing trims helps to successfully regulate well pressure and cope with kicks from gas entrained in the drilling mud.
