----------------------------------------------------------------------------------------------------------------
(1) Zones in open hole...................................... Cement plug(s) from at least 100 feet below the
bottom to 100 feet above the top of oil, gas, and
fresh-water zones to isolate fluids in the
strata.
[[Page 44266]]
(2) Open hole below casing.................................. (i) A cement plug set by the displacement method,
at least 100 feet above and below deepest casing
shoe;
(ii) A cement retainer with effective back-
pressure control set 50 to 100 feet above the
casing shoe, and a cement plug that extends at
least 100 feet below the casing shoe and at least
50 feet above the retainer; or
(iii) A bridge plug 50 feet to 100 feet above the
shoe with 50 feet of cement on top of the bridge
plug, for expected or known lost circulation
conditions.
(3) A perforated zone that is currently open and not (i) A method to squeeze cement to all
previously squeezed or isolated. perforations;
(ii) A cement plug set by the displacement method,
at least 100 feet above to 100 feet below the
perforated interval, or down to a casing plug,
whichever is less; or
(iii) If the perforated zones are isolated from
the hole below, you may use any of the plugs
specified in paragraphs (A) through (E) of this
paragraph instead of those specified in
paragraphs (3)(i) and (3)(ii) of this section:
(A) A cement retainer with effective back-
pressure control 50 to 100 feet above the top
of the perforated interval, and a cement plug
that extends at least 100 feet below the
bottom of the perforated interval with at
least 50 feet of cement above the retainer;
(B) A bridge plug set 50 to 100 feet above the
top of the perforated interval and at least 50
feet of cement on top of the bridge plug;
(C) A cement plug at least 200 feet in length,
set by the displacement method, with the
bottom of the plug no more than 100 feet above
the perforated interval;
(D) A through-tubing basket plug set no more
than 100 feet above the perforated interval
with at least 50 feet of cement on top of the
basket plug; or
(E) A tubing plug set no more than 100 feet
above the perforated interval topped with a
sufficient volume of cement so as to extend at
least 100 feet above the uppermost packer in
the wellbore and at least 300 feet of cement
in the casing annulus immediately above the
packer.
(4) A casing stub where the stub end is within the casing... (i) A cement plug at least 100 feet above and
below the stub end;
(ii) A cement retainer or bridge plug set at least
50 to 100 feet above the stub end with at least
50 feet of cement on top of the retainer or
bridge plug; or
(iii) A cement plug at least 200 feet long with
the bottom of the plug set no more than 100 feet
above the stub end.
(5) A casing stub where the stub end is below the casing.... A plug as specified in paragraph (a)(1) or (a)(2)
of this section, as applicable.
(6) An annular space that communicates with open hole and A cement plug at least 200 feet long set in the

ocean surface, you must pressure test each casing
annulus to verify isolation.
(7) A subsea well with unsealed annulus..................... A cutter to sever the casing, and you must set a
stub plug as specified in paragraphs (a)(4) and
(a)(5) of this section.
(8) A well with casing...................................... A cement surface plug at least 150 feet long set
in the smallest casing that extends to the mud
line with the top of the plug no more than 150
feet below the mud line.
(9) Fluid left in the hole.................................. A fluid in the intervals between the plugs that is
dense enough to exert a hydrostatic pressure that
is greater than the formation pressures in the
intervals.
