Combi Ram BOP

Used to provide positive protection against blow-outs and to secure the well in an emergency. This allows work to be safely carried out, under pressure, on surface equipment while the tubing is still in the wellbore.

The BOP closing design consists of a hydraulic actuator assembly connected to each ram assembly. This allows the rams to be hydraulically compressed around the tubing from opposite sides which creates a seal, thus containing well pressure below the rams. Pressure across the rams is equalized, through an equalizing assembly located across each ram assembly. This takes place prior to hydraulic retraction of the rams.


Combi Ram Configurations

Shear/Seal Rams: Upper set of rams that can shear tubing up to 3 1/2” and seal-off the well pressure.

Slip/Seal Rams: Lower set of rams that hold onto the tubing in place while shearing or for other applications and seal around the tubing, isolating the well bore below.
