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 work
circulation 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

*Upper Kelly Cock 3- ½ ‘’
Between the swivel and the kelly
joint to isolate the mud from the drill
string with a swivel, rotary house and
stand pipe in the event of a leak
Lower Kelly cock 3- ½ ‘’

To prevent mud from falling apart as a
freelance kelly kelly, which
accommodated the pressure of 5000 psi

15. *INSIDE BOP
*close / withstand pressure

17. Kill line 2 1/8” x 10.000 psi Choke 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 wells
Choke line
To stream high pressure fluid to the manifold in case of kick

18. *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

19. 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

*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

*Back Pressure Manifold serves to mud to mud

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