Oil and Gas and Sulphur Operations in the Outer Continental Shelf 
(OCS)--Minimum Blowout Prevention (BOP) System Requirements for Well-
Workover Operations Performed Using Coiled Tubing With the Production 
Tree in Place

AGENCY: Minerals Management Service (MMS), Interior.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This rule upgrades minimum blowout prevention and well control 
requirements for well-workover operations on the OCS performed using 
coiled tubing with the production tree in place. Since 1997, there have 
been eight coiled tubing-related incidents on OCS facilities. The rule 
helps prevent losses of well control, and provides for increased safety 
and environmental protection.

dates: Effective Date: This rule becomes effective on April 6, 2006.

Programs, at (703) 787-1033, Fax: (703) 787-1555, or e-mail at 
[email protected].

SUPPLEMENTARY INFORMATION: On June 22, 2004, MMS published a Notice of 
Proposed Rulemaking (69 FR 34625), titled ``Oil and Gas and Sulphur 
Operations in the Outer Continental Shelf--Minimum Blowout Prevention 
(BOP) System Requirements for Well-Workover Operations Performed Using 
Coiled Tubing with the Production Tree in Place.'' The proposed rule 
had a 60-day comment period that closed on August 23, 2004.

Comments on the Rule

    MMS received two sets of comments on the proposed rule. The 
comments came from the Offshore Operators Committee (OOC) and 
Halliburton, an oilfield service company and are posted at: http://www.mms.gov/federalregister/PublicComments/rulecomm.htm. Both sets of 
comments addressed specific technical issues related to coiled tubing 
operations.

I. OOC Comments on Specific Sections

    Comment on section 250.615(e)(1): OOC suggested that the ``Kill 
line outlet'' reference should be the ``Kill line inlet.'' This line is 
used for pumping kill fluid into the well and is not commonly used to 
flow out of the well.
    Response: MMS agrees with the suggestion, and revised the 
requirement.
    Comment on section 250.615(e)(5): OOC commented that the 
requirement for hydraulically controlled valves on both lines could be 
onerous for some situations, such as [plugged and abandoned] operations 
on dead or depleted wells with less than 3,500 expected pounds per 
square inch (psi) surface pressure.'' They suggested wording should be 
added to allow exceptions in special situations that would allow 
leaving the hydraulic actuation requirement off and using manual 
valves. ``Some circumstances require the ability to flow back from both 
sides of the flow cross unit.'' An operator should be allowed to comply 
by using dual full-opening valves on the kill line inlet. They asked, 
``Would this BOP rig up configuration comply with this clause?'' Also, 
the commenter questioned the ``* * * need to require one valve to be 
remotely controlled in all BOP rig up cases.'' The commenter further 
suggested, ``Possibly for wells with no H2S, or for those 
wells which have lower wellhead pressures, the use of dual manual 
valves could be sufficient.''
    Response: MMS agrees that two manual valves can be used on the kill 
line for all situations provided that a check valve is placed between 
the manual valves and the pump or manifold. However, the choke line 
needs to be equipped with two full-opening valves with at least one of 
these valves being remotely controlled for all operations.
    MMS does not consider it a safe practice to use the kill line to 
flow back fluids through the flow cross because the purpose of the kill 
line is to pump clean fluids into the wellbore. If the kill line is 
used to flow back fluids from the well, these well fluids may contain 
well debris that could erode critical safety equipment.
    Comment on section 250.615(e)(5): The proposed provision states, 
``For operations with expected surface pressure of 3,500 psi or 
greater, the kill line must be connected to a pump.'' OOC recommended 
that this statement be amended to read: ``For operations with expected 
surface pressure of 3,500 psi or greater, the kill line must be 
connected to a pump or manifold.''
    Response: MMS agrees with the suggestion and revised the 
requirement. In a well control situation, having the kill line 
connected to a manifold provides an equivalent degree of protection to 
both personnel and the environment as having the kill line connected to 
a pump.
    Comment on section 250.615(e)(7): The proposed provision states, 
``All connections used in the surface BOP system must be flanged.'' OOC 
asked MMS to clarify that the statement means the equipment shown in 
the table and does not include kill or flow lines. OOC recommended that 
all riser connections from wellhead to below the stripper must be 
flanged when expected surface pressures are greater than 3,500 psi. OOC 
also recommended that if the expected surface pressure is less than 
3,500 psi, the BOP kill inlet valves can be full-opening manual plug 
(hammer union type) valves.
    Response: MMS has modified 30 CFR 250.615 (e)(7) to clarify the 
flanging requirement for the BOP system. All connections in the surface 
BOP system from the tree to the uppermost required ram, as included in 
the table at Sec.  250.615(e)(1), need to be flanged, including the 
connections between the well control stack and the first full-opening 
valve on the choke line and kill line. This configuration needs to be 
adhered to for all expected surface pressures. Flanged connections 
provide better pressure integrity than hammer union type connections. 
Hammer union type connections are not allowed between the well control 
stack and the first full-opening valve on either the choke line or the 
kill line.
    Comment on section 250.616(a)(2): The proposed provision states, 
``Ram-type BOPs, related control equipment, including the choke and 
kill manifolds, and safety valves must be successfully tested to the 
rated working pressure of the BOP equipment or as otherwise approved by 
the District Manager.'' OOC recommended that this clause be changed to 
state, ``Ram-type BOPs, related control equipment, including the choke 
and kill manifolds, and safety valves must be successfully tested to 
1,500 psi above the maximum expected

[[Page 11311]]

shut in wellhead pressure (not to exceed the wellhead working 
pressure), or as otherwise approved by the District Manager.''
    Response: MMS did not make the suggested change. The requirement to 
test the rams, related control equipment, manifolds, and safety valves 
to the equipments' rated working pressure is viewed as an industry best 
practice by the offshore oil and gas community. If operators want to 
test this equipment to a lower pressure than its rated working 
pressure, they must provide the MMS District Manager with appropriate 
justification.
    Comment on section 250.616(a)(2): The proposed provision states, 
``Variable bore rams must be pressure tested against all sizes of drill 
pipe in the well, excluding drill collars.'' The commenter stated that 
this should not apply to coiled tubing functions and is a holdover from 
the source document used in writing this rule. OOC recommended that 
this be deleted.
    Response: MMS agrees with the comment and changed the variable bore 
pipe rams requirement to provide for pressure testing on tubulars 
including jointed and seamless pipe.
    Comment on section 250.616(f): OOC requested ``* * * that the 
required pressure test duration on coiled tubing BOP tests be changed 
from 10 minutes to 5 minutes. The American Petroleum Institute (API) 
Coiled Tubing Committee originally agreed on the 10-minute duration and 
then, after further discussion, agreed that it should be changed back 
to 5 minutes. The recommended change to 5 minutes would save 
approximately \1/2\ hour of testing each week.''
    Response: MMS did not make the suggested change. MMS believes that 
a 10-minute pressure test of the coiled tubing string more accurately 
shows string integrity than a 5-minute test. In such a test, it may 
take longer then 5 minutes to pressurize the entire string, depending 
on the length of the coiled tubing string, to accurately evaluate its 
integrity. MMS is aware of the discussions that the API Well 
Intervention Well Control Task Group had concerning this topic. Though 
the Task Group agreed to return to a 5-minute testing requirement, it 
was clear during the discussions that not every representative agreed 
with the change.

II. Halliburton Comments on Specific Sections

    Comment on section 250.615(e)(1): ``According to the proposed text, 
the blind-shear rams are required to be the lowermost rams.'' If an 
operator places ``* * * a set of dual combination rams below a flow 
cross, it would be a preference to have the pipe-slip combination ram 
as the lowermost ram to enable holding the cut coiled tubing. From the 
provided text, it may stand to reason that the primary objective is to 
have a blind-shear ram configuration as part of the BOP system and the 
sequential order is of less importance.''
    Response: MMS agrees with the suggestion and modified the table to 
reflect this change. Operators will have the option to place either the 
pipe rams or the blind-shear rams as the lowermost rams.
    Comment on section 250.615(e)(5): ``The placement of the two full-
opening valves is vague and left to interpretation. Connecting the 
valves to the well control stack could be accomplished by either 
directly to the stack or with 30 feet of connection line. A check valve 
in the kill line might need to be considered as a component 
requirement.''
    Response: MMS agrees with the comment that the placement of the two 
full-opening valves on both the choke line and the kill line is vague. 
We modified the wording to require that the kill line and choke line 
valves be installed between the well control stack and the respective 
line.
    If a check valve is used on the kill line of the BOP stack, it 
needs to be placed between two manual valves and the pump. If the check 
valve is used, it is considered a component of the BOP system and 
should be treated accordingly with regard to testing.
    Comment on section 250.615(e)(7): ``Lubricator sections are 
normally acceptable pressure containment devices and employ quick 
connections as end connections. Is the placement of the lubricator 
below the stripper well control component and above the Quad Ram 
function an acceptable configuration?''
    Response: Yes, placement of the lubricator below the stripper well 
control component and above the uppermost required ram is an 
appropriate and common configuration.
    Comment on section 250.616(a): ``There could be some confusion 
regarding the pressure test amount for the stripper well components. 
Are stripper well components classified as related control equipment?''
    Response: MMS agrees that the proposed rule could be confusing 
concerning the pressure testing requirements for the stripper. 
Therefore, we changed the wording in this section to reflect that 
strippers need to be tested like other BOP components.
    Comment on section 250.616(f): ``There could be some confusion 
regarding the test period. Is the coiled tubing pipe the only 10-minute 
test interval, and the rest of the BOP system components a 5-minute 
test interval requirement?''
    Response: MMS agrees that the proposed rule could be confusing in 
regards to the required pressure test period for the coiled tubing 
string. We changed the regulation to indicate that the 10-minute 
pressure test is just for the coiled tubing string.

Differences Between Proposed and Final Rules Not Directly Related to 
Comments

    In addition to changes we made in the rule in response to public 
comments, MMS has reworded several sections in the final rule to 
further clarify the requirements. The following are the changes by 
section:
    Section 250.615(e)(1)--We expanded the title of the first column in 
the table to reflect a pressure range of less than or equal to 3,500 
psi. This change more accurately reflects our intentions.
    Section 250.615(e)(1)--We removed the requirement to have two sets 
of hydraulically-operated pipe rams for BOP configurations when 
expected surface pressures are greater than 3,500 psi. This change 
corrects an oversight.
    Section 250.616(a)--We removed the word ``sequentially'' from the 
last sentence of this section so that the testing of the choke and kill 
manifold valves does not need to be conducted in any predetermined 
order.

Procedural Matters

Regulatory Planning and Review (Executive Order 12866)

    This is not a significant rule under Executive Order 12866, and 
does not require review by the Office of Management and Budget (OMB).
    a. The final rule will not have an annual effect on the economy of 
$100 million or more, or adversely affect in a material way the 
economy, a sector of the economy, productivity, competition, jobs, the 
environment, public health or safety, or state, local, or tribal 
governments or communities. The final rule will not create an adverse 
effect upon the ability of the United States offshore oil and gas 
industry to compete in the world marketplace, nor will the final rule 
adversely affect investment or employment factors locally. The economic 
effects of the rule will not be significant. This rule will not add 
significant dollar amounts to the cost of each well-workover operation 
involving the use of coiled tubing with the production tree in place. 
During February 2003, MMS surveyed, by

[[Page 11312]]

phone, five of the eight coiled tubing operating companies working on 
the OCS to collect information on the impact this rule would have on 
their operations. All data indicates that these offshore coiled tubing 
companies have upgraded their field procedures and equipment to the 
same or a similar process as that required under the final rule. None 
of the companies in this survey could provide dollar values for the 
implementation of this rule because they had incorporated most of the 
suggested measures into their work processes in 1999. Some of the 
coiled tubing operating companies contacted are already using dual 
check valves in the bottom of their coiled tubing string. According to 
these companies, this practice was put into place several years ago for 
OCS operations. For these reasons, MMS concluded that direct annual 
costs to industry for the final rule will have a minor economic effect 
on the offshore oil and gas industry.
    b. This rule will not create inconsistencies with other agencies' 
actions. The rule does not change the relationships of the OCS oil and 
gas leasing program with other agencies. These relationships are all 
encompassed in agreements and memoranda of understanding that will not 
change with this final rule.
    c. This final rule will not affect entitlements, grants, loan 
programs, or the rights and obligations of their recipients. The rule 
includes specific well-workover process standards to prevent accidents 
and environmental pollution on the OCS.
    d. This rule will not raise novel legal or policy issues. There is 
a precedent for actions of this type under regulations dealing with the 
Outer Continental Shelf Lands Act and the Oil Pollution Act of 1990.

Regulatory Flexibility Act (RFA)

    MMS has determined that this final rule will not have a significant 
economic effect on a substantial number of small entities. While the 
rule will affect some small entities, the economic effects of the rule 
will not be significant.
    The regulated community for this rule consists of about eight 
companies specializing in offshore oil and gas coiled tubing 
technologies. Of these companies, three are considered to be ``small.'' 
The small companies to be affected by this rule are all represented by 
the North American Industry Classification System (NAICS) Code 211111 
(crude petroleum and natural gas extraction).
    MMS's analysis of the economic impacts of this final rule indicates 
that direct implementation costs to both large and small companies 
cannot be accurately assessed because the industry has already 
implemented most of the technological requirements required in this 
final rule. Regardless of company size, the final rule will have a 
minor economic effect on some oil and gas offshore platform operators 
on the OCS. In the overwhelming majority of cases, operators choose to 
perform improved and safer well-workover procedures involving coiled 
tubing operations on their own initiative, not because of an MMS safety 
inspection or regulation. The final rule will add relatively little to 
the cost of a well-workover operation. Thus, there will not be a 
significant impact on a substantial number of small entities under the 
RFA (5 U.S.C. 601 et seq.). The rule will not cause the business 
practices of the majority of these companies to change.
    Your comments are important. The Small Business and Agriculture 
Regulatory Enforcement Ombudsman and 10 Regional Fairness boards were 
established to receive comments from small businesses about federal 
agency enforcement actions. The Ombudsman will annually evaluate the 
enforcement activities and rate each agency's responsiveness to small 
business. If you wish to comment on the enforcement actions of MMS, 
call toll-free at (888) 734-3247.

Small Business Regulatory Enforcement Fairness Act (SBREFA)

    This final rule is not a major rule under 5 U.S.C. 804(2), the 
SBREFA. The rule will not significantly increase the cost of well-
workovers. If there is an increase, it is not a large cost compared to 
the overall cost of a well-workover. Moreover, it may significantly 
reduce the possibility of a fatal or environmentally damaging accident 
during the course of a well-workover. Such an accident could be 
economically disastrous for a small entity. Based on economic analysis:
    a. This rule does not have an annual effect on the economy of $100 
million or more. As indicated in MMS's cost analysis, direct annual 
costs to industry for the rule could not be assessed adequately. The 
final rule will have a minor economic effect on the offshore oil and 
gas industries.
    b. This rule will not cause a major increase in costs or prices for 
consumers, individual industries, federal, state, or local government 
agencies, or geographic regions.
    c. This rule does not have significant adverse effects on 
competition, employment, investment, productivity, innovation, or the 
ability of U.S.-based enterprises to compete with foreign-based 
enterprises.

Paperwork Reduction Act (PRA) of 1995

    The final revisions to 30 CFR part 250, subpart F, Oil and Gas 
Well-Workover Operations, do not change the information collection 
requirements in current regulations.
    OMB has approved the referenced information collection requirements 
under OMB control numbers 1010-0043 (expiration date October 31, 2007) 
for 30 CFR 250 subpart F and 1010-0141 (expiration date August 31, 
2008) for subpart D Drilling, Form MMS-124, Application for Permit to 
Modify. The revised sections in the final rule do not affect the 
currently approved burdens (19,459 approved hours for 1010-0043 and 
163,714 for 1010-0141). Therefore, an information collection request 
(form OMB 83-I) has not been submitted to OMB for review and approval 
under section 3507(d) of the PRA.

Unfunded Mandates Reform Act (UMRA) of 1995

    This rule does not contain any unfunded mandates to state, local, 
or tribal governments; nor would it impose significant regulatory costs 
on the private sector. Anticipated costs to the private sector will be 
far below the $100 million threshold for any year that was established 
by UMRA.

Takings Implications Assessment (Executive Order 12630)

    The Department of the Interior (DOI) certifies that this rule does 
not represent a governmental action capable of interference with 
constitutionally protected property rights.

Civil Justice Reform (Executive Order 12988)

    DOI has certified to OMB that this regulation meets the applicable 
civil justice reform standards provided in sections 3(a) and 3(b) (2) 
of Executive Order 12988.

Federalism (Executive Order 13132)

    According to Executive Order 13132, this rule does not have 
significant Federalism effects. This rule does not change the role or 
responsibilities of federal, state, and local governmental entities. 
The rule does not relate to the structure and role of states, and will 
not have direct, substantive, or significant effects on states.

National Environmental Policy Act (NEPA) of 1969

    MMS has analyzed this rule according to the criteria of NEPA and 
516 Departmental Manual 6, Appendix

[[Page 11313]]

10.4C. MMS reviewed the criteria of the Categorical Exclusion Review 
(CER) for this action during February 2003, and concluded that this 
rulemaking does not represent an exception to the established criteria 
for categorical exclusion, and that its impacts are limited to 
administrative, economic, or technological effects. Therefore, 
preparation of an environmental document is not required, and further 
documentation of this CER is not required.

Consultation and Coordination With Indian Tribal Governments (Executive 
Order 13175)

    In accordance with Executive Order 13175, this final rule does not 
have tribal implications that impose substantial direct compliance 
costs on Indian tribal governments.

    (2) You may use a set of hydraulically-operated combination rams 
for the blind rams and shear rams.
    (3) You may use a set of hydraulically-operated combination rams 
for the hydraulic two-way slip rams and the hydraulically-operated pipe 
rams.
    (4) You must attach a dual check valve assembly to the coiled 
tubing connector at the downhole end of the coiled tubing string for 
all coiled tubing well-workover operations. If you plan to conduct 
operations without downhole check valves, you must describe alternate 
procedures and equipment in Form MMS-124, Application for Permit to 
Modify and have it approved by the District Manager.
    (5) You must have a kill line and a separate choke line. You must 
equip each line with two full-opening valves and at least one of the 
valves must be remotely controlled. You may use a manual valve instead 
of the remotely controlled valve on the kill line if you install a 
check valve between the two full-opening manual valves and the pump or 
manifold. The valves must have a working pressure rating equal to or 
greater than the working pressure rating of the connection to which 
they are attached, and you must install them between the well control 
stack and the choke or kill line. For operations with expected surface 
pressures greater than 3,500 psi, the kill line must be connected to a 
pump or manifold. You must not use the kill line inlet on the BOP stack 
for taking fluid returns from the wellbore.
    (6) You must have a hydraulic-actuating system that provides 
sufficient accumulator capacity to close-open-close each component in 
the BOP stack. This cycle must be completed with at least 200 psi above 
the pre-charge pressure, without assistance from a charging system.
    (7) All connections used in the surface BOP system from the tree to 
the uppermost required ram must be flanged, including the connections 
between the well control stack and the first full-opening valve on the 
choke line and the kill line.

4. Amend Sec.  250.616 by revising paragraph (a); redesignating 
paragraphs (d) and (e) as paragraphs (f) and (g); adding new paragraphs 
(d) and (e); and revising redesignated paragraph (f) to read as 
follows:


Sec.  250.616  Blowout preventer system testing, records, and drills.

    (a) BOP Pressure Tests. When you pressure test the BOP system you 
must conduct a low-pressure test and a high-pressure test for each 
component. You must conduct the low-pressure test before the high-
pressure test. For purposes of this section, BOP system components 
include ram-type BOP's, related control equipment, choke and kill 
lines, and valves, manifolds, strippers, and safety valves. Surface

BOP systems must be pressure tested with water.
    (1) Low Pressure Tests. All BOP system components must be 
successfully tested to a low pressure between 200 and 300 psi. Any 
initial pressure equal to or greater than 300 psi must be bled back to 
a pressure between 200 and 300 psi before starting the test. If the 
initial pressure exceeds 500 psi, you must bleed back to zero before 
starting the test.
    (2) High Pressure Tests. All BOP system components must be 
successfully tested to the rated working pressure of the BOP equipment, 
or as otherwise approved by the District Manager. The annular-type BOP 
must be successfully tested at 70 percent of its rated working pressure 
or as otherwise approved by the District Manager.
    (3) Other Testing Requirements. Variable bore pipe rams must be 
pressure tested against the largest and smallest sizes of tubulars in 
use (jointed pipe, seamless pipe) in the well.
* * * * *
    (d) You may conduct a stump test for the BOP system on location. A 
plan describing the stump test procedures must be included in your Form 
MMS-124, Application for Permit to Modify, and must be approved by the 
District Manager.
    (e) You must test the coiled tubing connector to a low pressure of 
200 to 300 psi, followed by a high pressure test to the rated working 
pressure of the connector or the expected surface pressure, whichever 
is less. You must successfully pressure test the dual check valves to 
the rated working pressure of the connector, the rated working pressure 
of the dual check valve, expected surface pressure, or the collapse 
pressure of the coiled tubing, whichever is less.
    (f) You must record test pressures during BOP and coiled tubing 
tests on a pressure chart, or with a digital recorder, unless otherwise 
approved by the District Manager. The test interval for each BOP system 
component must be 5 minutes, except for coiled tubing operations, which 
must include a 10 minute high-pressure test for the coiled tubing 
string. Your representative at the facility must certify that the 
charts are correct.
