BLOWOUT PREVENTER (BOP) EQP.

FUNCTION BOP EQP.

Close well at situation there a pipe or not pipe stripping in or stripping out

Withstand pressure well that arise and can be passed all the equipment who were used to operating the drilling / rework

Control well pressure and can be used for workcirculation kill kick

Hang (hanging off) and cut the drill pipe in an emergency.

Having a system backup equipment if one breaks down, specifically for high pressure wells

* INSIDE BOP*close / withstand pressure from the string during a kick or bursts.

Kill Line Choke Line

Kill line 2 1/8” x 10.000 psiChoke line 3-1/8’’ x

10.000 psi

* Kill line serves as a conduit to the injection of fluid into the well if

necessary to shut down wellsChoke line

To stream high pressure fluid to the manifold in case of kick

*Back Pressure Manifold

CHOKE MANIFOLD OR BACK PRESSURE MANIFOLD

serves as a flow divider in the event kick by dividing the flow of appropriate safety procedures

Accumulator Unit

o Accumulator unit steel which contains high-pressure nitrogen

o Known for Closing Unit has the main function to close the BOP during a kick

* CONCLUSION*BOP (Blowout Preventer) is a tool used to

cover / hold kick or the flow of formation fluids into the wellbore uncontrolled

*Source of power Acummulator is the water pump and Electric pump

*Back Pressure Manifold serves to mud to mud gas to separator, reserve pit, or flare

*BOP handling system on RIG PDSI #15.3/N110-M wells relatively good, as long as the drilling does not problem
