The purpose of the accumulator system
is to provide closing energy to all
members of the blowout preventer
stack. This is usually done with a
hydraulic system designed and built to
provide closing power to the equipment
in 5 seconds or less and to maintain the
required pressures as desired.

1. Ability to close a minimum of three
members of the stack, one of which must be
spherical, w/o having to recharge the
2. A total of 50% of the original fluid should
remain as a reserve after accumulator
3. A minimum pressure of 12psi is required to
insure that the preventers remain close.
115 Fluid Density Control
The primary well control tool available
to the drilling supervisor is the
hydrostatic pressure of the drilling fluid
in the well. The drilling fluid, or mud, is
used to prevent a well from kicking and
should a kick occur, the mud is used to
kill the kick and regain control of the
