The table in this section describes actions that lessees must take when certain situations occur with BOP systems during drilling activities. ------------------------------------------------------------------------
(a) BOP equipment does not hold the Correct the problem and
required pressure during a test, retest the affected
equipment.(b) Need to repair or replace a surface or First place the well in a
subsea BOP system, safe, controlled condition
(e.g., before drilling out
a casing shoe or after
setting a cement plug,
bridge plug, or a packer).(c) Need to postpone a BOP test due to Record the reason for
well-control problems such as lost postponing the test in the
circulation, formation fluid influx, or driller's report and
stuck drill pipe, conduct the required BOP
test on the first trip out
of the hole.(d) BOP control station or pod that does Suspend further drilling
not function properly, operations until that
station or pod is operable.(e) Want to drill with a tapered drill- Install two or more sets of
string, conventional or variable-
bore pipe rams in the BOP
stack to provide for the
following: two sets of rams
must be capable of sealing
around the larger-size
drill string and one set of
pipe rams must be capable
of sealing around the
smaller-size drill string.(f) Install casing rams in a BOP stack, Test the ram bonnets before
running casing.(g) Want to use an annular BOP with a Demonstrate that your well
rated working pressure less than the control procedures or the
anticipated surface pressure, anticipated well conditions
will not place demands
above its rated working
pressure and obtain
approval from the District
Manager.(h) Use a subsea BOP system in an ice- Install the BOP stack in a
scour area, well cellar. The well
cellar must be deep enough
to ensure that the top of
the stack is below the
deepest probable ice-scour
(i) You activate blind-shear rams or Retrieve, physically
casing shear rams during a well control inspect, and conduct a full
situation, in which pipe or casing is pressure test of the BOP
sheared, stack after the situation
is fully controlled.(j) Need to remove the BOP stack Have a minimum of two
barriers in place prior to
BOP removal. The BSEE
District Manager may
require additional
barriers.------------------------------------------------------------------------ [76 FR 64462, Oct. 18, 2011, as amended at 77 FR 50894, Aug. 22, 2012]
