Annular Casing Pressure Managementfor Offshore Wells

AGENCY : Minerals Management Service(MMS), Interior.ACTION : Final rule.

SUMMARY : This final rule will establishregulations to address sustained casingpressure in oil and gas wells completedin the Outer Continental Shelf.Sustained casing pressure is a problemthat, if left untreated, could causeserious harm to human life and theenvironment. The final rule willestablish criteria for monitoring andtesting of wells with sustained casingpressure, and will also incorporate theAmerican Petroleum InstitutesRecommended Practice for managingannular casing pressure. Newregulations are needed because thecurrent regulations do not adequatelyaddress the requirements for wells thathave sustained casing pressure. Thisrule will promote human safety andenvironmental protection, and requireOuter Continental Shelf lessees tofollow best industry practices for wellswith sustained casing pressure.DATES : Effective Date: This rule becomeseffective on June 3, 2010. Theincorporation by reference of thepublication listed in the regulation isapproved by the Director of the FederalRegister as of June 3, 2010.FOR FURTHER INFORMATION CONTACT : Forcomments or questions on proceduralissues, contact Kirk Malstrom, Office of Offshore Regulatory Programs,Regulations and Standards Branch, 7037871751. For questions on technicalissues, contact Russell Hoshman,Technical Assessment and Operations

Support Section, Gulf of Mexico OuterContinental Shelf Region, 5047362627.SUPPLEMENTARY INFORMATION : On July31, 2009, MMS published the proposedrule Annular Casing PressureManagement for Offshore Wells (74 FR38147). The comment period for theproposed rule was open for 60 days.During the comment period, MMSreceived three comments. Twocomments were in favor of this rule andthe remaining comment was notassociated with this rulemaking.

There are no changes between theproposed and final rule language. Thereare also no changes to the proceduralmatters discussion regardinginformation collection requirements,cost estimates, benefits, or impacts tosmall entities.

Public Comments: The MMS receivedthree comments on the proposed rule1010AD47 Annular Casing Pressure

Management for Offshore Wells. Thecomments received are summarized asfollows:

British Petroleum (BP)BP, a largeoil and gas company, expressed theimportance of this rule and how theyhave been involved with MMS andindustry to develop the industrystandard.

Offshore Operators Committee(OOC)OOC, a large oil and gasindustry organization, stated theirsupport of this rulemaking and theirinvolvement with the industry standard.

Private citizenThis comment isnot associated with this rulemaking.

The two applicable commentsreceived on the proposed rule are fullysupportive of this rulemaking.

Background: Sustained casingpressure (SCP) is pressure between thecasing and the wells tubing, or betweenstrings of casing, that rebuilds after

being bled down. The SCP represents anongoing safety hazard and can causeserious or immediate harm or damage tohuman life, the marine and coastalenvironment, and property. The oil andgas industry in the Gulf of Mexico(GOM) has suffered serious accidents asa result of high SCP, and the lack of

proper control and monitoring of thesepressures. With over 8,000 affectedwells in the GOM with SCP in at leastone annulus, immediate elimination of all SCP has proved to be impractical andexceedingly costly. The MMS hassought to identify and eliminate SCP incases that represent a clear hazard to thesafety of personnel or the environment,and establish a monitoring system forthe rest, all the while working towardselimination of the problem.

The MMS is currently addressing theissue of casing pressure in a 1994 Letter

to Lessees (LTL) and a 2009 Notice toLessees (NTL), 2009 G22, August 3,2009. Once the final rulemaking

becomes effective, both the 1994 LTLand the 2009 NTL on casing pressurewill be rescinded.

Included in this final rule is theincorporation of a jointly developedindustry standard that addressesmanagement of casing pressure. TheAmerican Petroleum Institute (API),industry, and MMS have workedcollectively to produce APIRecommended Practice (RP) 90. Asexplained in API RP 90, Section 3,Annular Casing Pressure ManagementProgram, this RP is based onestablishing an annular casing pressuremanagement program that filters outnon-problematic wells that present anacceptable level of risk, thus allowingfor a more focused effort on wells thatare problematic. The managementprogram, as outlined in API RP 90,

includes monitoring, diagnostic testing,determining maximum allowablewellhead operating pressure (MAWOP)for each annulus, documentation, andrisk assessment considerations.

For further background informationon this rulemaking, refer to thepublished proposed rule 1010AD47Annular Casing Pressure Managementfor Offshore Wells (74 FR 38147, July31, 2009).

Procedural Matters

Regulatory Planning and Review (Executive Order (E.O.) 12866)

This final rule is not a significant ruleas determined by the Office of Management and Budget (OMB) and isnot subject to review under E.O. 12866.

(1) This final rule will not have anannual effect of $100 million or more onthe economy. It will not adversely affectin a material way the economy,productivity, competition, jobs, theenvironment, public health or safety, orState, local, or tribal governments orcommunities. There will be some costsassociated with this rulemaking, mostlyfor diagnostic testing, MAWOPcalculations, and reporting to MMS.

Taking into account paperwork burdenrequirements, diagnostic testing, andMAWOP calculations, the costsassociated with this rulemaking will beapproximately $5 million industry-wide. The final rule will not require anynew equipment to be installed anddiagnostic testing is currently beingdone throughout industry and is notnew.

(2) This final rule will not create aserious inconsistency or otherwiseinterfere with an action taken orplanned by another agency.

(3) This final rule will not alter the budgetary effects of entitlements, grants,user fees, or loan programs or the rightsor obligations of their recipients. Thechanges in the final rule are strictlyplanning requirements for managementof annular casing pressure in offshorewells.

(4) This final rule will not raise novellegal or policy issues arising out of legalmandates, the Presidents priorities, orthe principles set forth in E.O. 12866.Regulatory Flexibility Act

The Department of the Interiorcertifies that this final rule will not havea significant economic effect on asubstantial number of small entitiesunder the Regulatory Flexibility Act (5U.S.C. 601 et seq. ).

This rulemaking will affect lesseesand operators of leases and pipelineright-of-way holders in the OCS. Thiscould include about 130 active Federaloil and gas lessees. Small entities thatoperate under this rule are coded underthe Small Business AdministrationsNorth American Industry ClassificationSystem (NAICS) codes 211111, CrudePetroleum and Natural Gas Extraction,and 213111, Drilling Oil and Gas Wells.For these NAICS code classifications, asmall company is one with fewer than500 employees. Based on these criteria,an estimated 70 percent (91) of thesecompanies are considered small. Thisfinal rule, therefore, will affect asubstantial number of small entities.This rule will affect every well in theOCS, and every operator both large andsmall will have the same criteria perwell regardless of company size.

Nonetheless, this rulemaking will nothave a significant economic effect on asubstantial number of small entities

because management of annular casingpressure will be a moderate cost, mostlyattributable to diagnostic testing. Takinginto account recordkeeping, diagnostictesting, and MAWOP calculations, thecosts associated with this rulemakingwill be approximately $5 millionindustry-wide. In comparison, toremediate the approximate 8,000 wellswith SCP (approximately $250,000 per

well) would cost approximately $2 billion. The costs that are associatedwith this rulemaking will be minorwhen compared to SCP remediationcosts and will not impede a company of any size.

Your comments are important. TheSmall Business and AgricultureRegulatory Enforcement Ombudsmanand 10 Regional Fairness Boards wereestablished to receive comments fromsmall businesses about Federal agencyenforcement actions. The Ombudsmanwill annually evaluate the enforcement

activities and rate each agencysresponsiveness to small business. If youwish to comment on the actions of MMS, call 18887343247. You maycomment to the Small BusinessAdministration without fear of retaliation. Allegations of discrimination/retaliation filed with theSmall Business Administration will beinvestigated for appropriate action.Small Business Regulatory Enforcement Fairness Act

This final rule is not a major ruleunder the Small Business RegulatoryEnforcement Fairness Act (5 U.S.C. 801et seq. ). This final rule:

a. Will not have an annual effect onthe economy of $100 million or more.

b. Will not cause a major increase incosts or prices for consumers,individual industries, Federal, State, orlocal government agencies, orgeographic regions.

c. Will not have significant adverseeffects on competition, employment,investment, productivity, innovation, orthe ability of U.S.-based enterprises tocompete with foreign-based enterprises.

Unfunded Mandates Reform Act of 1995This final rule will not impose an

unfunded mandate on State, local, ortribal governments or the private sectorof more than $100 million per year. Thefinal rule will not have a significant orunique effect on State, local, or tribalgovernments or the private sector. Astatement containing the informationrequired by the Unfunded MandatesReform Act (2 U.S.C. 1501 et seq. ) is notrequired.

Takings Implication Assessment (E.O.12630)

Under the criteria in E.O. 12630, thisfinal rule does not have significanttakings implications. The final rule isnot a governmental action capable of interference with constitutionallyprotected property rights. A TakingsImplication Assessment is not required.

Federalism (E.O. 13132)Under the criteria in E.O. 13132, this

final rule does not have federalismimplications. This final rule will notsubstantially and directly affect therelationship between the Federal andState governments. To the extent thatState and local governments have a rolein OCS activities, this final rule will notaffect that role. A FederalismAssessment is not required.

Civil Justice Reform (E.O. 12988)This rule complies with the

requirements of E.O. 12988.Specifically, this rule:


7/30/2019 MMS Regulations 2010-10291

Meets the criteria of section 3(a)requiring that all regulations bereviewed to eliminate errors andambiguity and be written to minimizelitigation; and

Meets the criteria of section 3(b)(2)requiring that all regulations be writtenin clear language and contain clear legalstandards.Consultation With Indian Tribes (E.O.13175)

Under the criteria in E.O. 13175, wehave evaluated this final rule anddetermined that it has no substantialeffects on federally recognized Indiantribes. There are no Indian or triballands in the OCS nor tribally owned

businesses subject to the regulation.Paperwork Reduction Act (PRA)

The final rule contains no newreporting or recordkeepingrequirements, and an Office of Management and Budget (OMB)submission under the PRA (44 U.S.C.3501 et seq. ) is not required. The PRAprovides that an agency may notconduct or sponsor a collection of information unless it displays acurrently valid OMB control number.Until OMB approves a collection of information and assigns a controlnumber, you are not required torespond. The final regulations willreplace the references to LTLs and NTLswith specific cites to the Code of Federal Regulations. The finalrulemaking refers to, but does notchange, information collection

requirements under approved OMBControl Number 10100067 (18,756hours, expiration 12/31/2010).National Environmental Policy Act

This rule does not constitute a majorFederal action significantly affecting thequality of the human environment. Adetailed statement under the NationalEnvironmental Policy Act of 1969 is notrequired because we reached a Findingof No Significant Impact. A copy of theEnvironmental Assessment can beviewed at http://www.Regulations.gov. (type in environmental assessment forthe document type and use thekeyword/ID MMS2007OMM0068. )Data Quality Act

In developing this rule, we did notconduct or use a study, experiment, orsurvey requiring peer review under theData Quality Act (Pub. L. 106554, app.C section 515, 114 Stat. 2763, 2763A153154).Effects on the Energy Supply (E.O.13211)

This rule is not a significant energyaction under the definition in E.O.13211. A Statement of Energy Effects isnot required.List of Subjects in 30 CFR Part 250

subpart, you must follow therequirements of this subpart.

250.519 How often do I have to monitorfor casing pressure?

You must monitor for casing pressurein your well according to the followingtable:

If you have * * * you must monitor * * * with a minimum one pressure data point recorded per * * *

(a) fixed platform wells, ................... monthly, ......................................... month for each casing.(b) subsea wells, ............................. continuously, .................................. day for the production casing.(c) hybrid wells, ............................... continuously, .................................. day for each riser and/or the production casing.(d) wells operating under a casing

pressure request on a mannedfixed platform,

daily, .............................................. day for each casing.

(e) wells operating under a casingpressure request on an un-manned fixed platform,

weekly, ........................................... week for each casing.

250.520 When do I have to perform acasing diagnostic test?

(a) You must perform a casingdiagnostic test within 30 days after first

observing or imposing casing pressureaccording to the following table:

If you have a * * * you must perform a casing diagnostic test if * * *

(1) fixed platform well, .................... the casing pressure is greater than 100 psig.(2) subsea well, ............................... the measurable casing pressure is greater than the external hydrostatic pressure plus 100 psig measured

at the subsea wellhead.(3) hybrid well, ................................ a riser or the production casing pressure is greater than 100 psig measured at the surface.

(b) You are exempt from performing adiagnostic pressure test for theproduction casing on a well operatingunder active gas lift.

250.521 How do I manage the thermaleffects caused by initial production on anewly completed or recompleted well?

A newly completed or recompletedwell often has thermal casing pressure

during initial startup. Bleeding casingpressure during the startup process isconsidered a normal and necessaryoperation to manage thermal casingpressure; therefore, you do not need toevaluate these operations as a casingdiagnostic test. After 30 days of continuous production, the initialproduction startup operation is

complete and you must perform casingdiagnostic testing as required in 250.520 and 250.522.

250.522 When do I have to repeat casingdiagnostic testing?

Casing diagnostic testing must berepeated according to the followingtable:

When * * * you must repeat diagnostic testing * * *

(a) your casing pressure request approved term has expired, ................ immediately.(b) your well, previously on gas lift, has been shut-in or returned to

flowing status without gas lift for more than 180 days,immediately on the production casing (A annulus). The production cas-

ing (A annulus) of wells on active gas lift are exempt from diagnostictesting.

(c) your casing pressure request becomes invalid, ................................. within 30 days.(d) a casing or riser has an increase in pressure greater than 200 psig

over the previous casing diagnostic test,within 30 days.

(e) after any corrective action has been taken to remediate undesirablecasing pressure, either as a result of a casing pressure request de-nial or any other action,

within 30 days.

(f) your fixed platform well production casing (A annulus) has pressure

exceeding 10 percent of its minimum internal yield pressure (MIYP),except for production casings on active gas lift,

once per year, not to exceed 12 months between tests.

(g) your fixed platform wells outer casing (B, C, D, etc., annuli) has apressure exceeding 20 percent of its MIYP,

once every 5 years, at a minimum.

250.523 How long do I keep records ofcasing pressure and diagnostic tests?

Records of casing pressure anddiagnostic tests must be kept at the fieldoffice nearest the well for a minimum of 2 years. The last casing diagnostic testfor each casing or riser must be retained

at the field office nearest the well untilthe well is abandoned.

250.524 When am I required to takeaction from my casing diagnostic test?

You must take action if you have anyof the following conditions:
