---|---|---|
REC177-3283 | 32 - Doctrine, standards, and reform | A separate, identifiable barrier manual should be agreed upon and used by licensees, rig operators, and cementing contractors. These manuals should set out best industry practice in relation to achieving and maintaining well integrity. They should describe barrier types, barrier standards, general principles of well integrity, testing and verification methods and technologies, standard operating procedures (including procedures for the capture and communication of relevant information within and between relevant stakeholder entities). Barrier manuals should address blowout control during drilling, completion, re‐entry, tie‐back of casing strings and so on. Barrier manuals should be the subject of expert external review, and should be regularly updated. |
REC177-3312 | 32 - Doctrine, standards, and reform | The BOP and rig should not move from a well until barrier integrity has been verified. |
REC177-3329 | 17 - Assets and technology | Logistics management of well control equipment should be conducted in such a way as to operate as a check against deficient well control practices, for example, use of serial numbers to track availability, testing, and deployment of well control equipment. |
REC177-3354 | 32 - Doctrine, standards, and reform | NOPSA develop a policy of engagement with operators so as to enable experts (including safety experts) to canvas all available options for well control in the event of a blowout. |
REC177-3298 | 32 - Doctrine, standards, and reform | Reliance upon one barrier against a blowout must not take place except with the prior written approval of the relevant regulator and then only in a true emergency situation (see below). |
REC177-3317 | 32 - Doctrine, standards, and reform | Any equipment (including PCCCs) used as, or to install, a barrier should be manufactured for that purpose and be generally recognised as fit for purpose. If equipment is designed in‐house by a licensee or rig operator it should not be approved for use unless and until it is subjected to expert external analysis. |
REC177-3337 | 12 - EM agency and authority | Supervision/oversight of well control operations (within licensees, rig operators and by regulators) must occur without assuming adherence to good oilfield practice. The opposite assumption should prevail: namely adherence to good oilfield practice may well be compromised by the pursuit of time and cost savings. |
REC177-3363 | 32 - Doctrine, standards, and reform | DEWHA, in concert with AMSA and with expert input, should develop ‘off the shelf’ monitoring programs that can be speedily implemented following incidents in Commonwealth waters. In this context, the utility of the current Scientific Monitoring program should be peer reviewed to inform future policy. |
REC177-3305 | 32 - Doctrine, standards, and reform | Cement integrity should be evaluated wherever practicable by way of cement evaluation tests, rather than relying on pre‐operational calculations of cement and displacement fluid volumes. |
REC177-3323 | 32 - Doctrine, standards, and reform | Where multiple wells are drilled, operations and occurrences at one well must be carefully assessed for any implications with respect to well control at other wells. |
REC177-3342 | 32 - Doctrine, standards, and reform | Written (rather than verbal) approval from the DA (or new regulator) should be obtained before the commencement of well activities that lead to a physical change of a wellbore, other than in a true emergency situation (requiring amendment to regulation 17 of the Management of Well Operations Regulations). |
REC177-3373 | 32 - Doctrine, standards, and reform | Arrangements should be developed to minimise duplication between the EPBC Act and the OPGSS Act Environment Regulation. |
REC177-3280 | 32 - Doctrine, standards, and reform | Well construction and management plans should include provision for an independent compliance review of well integrity (i) in the event of stipulated triggers; and (ii) at least once in the period between perceived achievement of well integrity and production. The independent compliance review should be undertaken by an expert who is not involved in the day‐to‐day drilling operations. Reviews should be completed in sufficient time to enable results to be implemented in a meaningful manner. |
REC177-3311 | 32 - Doctrine, standards, and reform | Horizontal or high angle penetration of a reservoir should be avoided wherever practicable until such time as the apparent problems associated with the cementing of a casing shoe in these situations are satisfactorily overcome. If a casing string does penetrate a well horizontally or at a high angle, standard practice should be to install two secondary barriers in addition to the cemented casing shoe. |
REC177-3328 | 32 - Doctrine, standards, and reform | All communications between on‐rig and onshore personnel relating to well control should be documented in a timely manner. |
REC177-3353 | 32 - Doctrine, standards, and reform | The regulatory regime should also impose an obligation on an operator to ascertain the availability, and provide details to the regulator, of any potential relief well rigs, prior to the commencement of drilling operations (including prior to each phase of a drilling operation where applicable). |
REC177-3297 | 32 - Doctrine, standards, and reform | A minimum of two barriers should be in place at all times (including during batched operations) whenever it is reasonably practicable to do so. |
REC177-3316 | 32 - Doctrine, standards, and reform | Wells should be re‐entered with a BOP in place unless a documented risk assessment indicates that well control can be maintained at all times. |
REC177-3336 | 12 - EM agency and authority | Achievement and maintenance of well control should be written into the job responsibilities of key personnel, at every level up to and including CEOs. That is, a functional line of accountability for well control must exist up to, and including, CEOs. |
REC177-3362 | 32 - Doctrine, standards, and reform | Procedures for the approval of development projects should ensure that conditions of approval are comprehensive and clearly set out the obligations of their proponents in relation to environmental matters (including expected monitoring and remediation obligations). |
REC177-3304 | 26 - Research | It is recommended that industry, regulators, and training/research institutions liaise with one another with a view to developing better techniques for testing and verifying the integrity of cemented casing shoes as barriers (particularly in atypical situations such as where the casing shoe is located within a reservoir in a horizontal or high angle position at great depth). |
REC177-3322 | 32 - Doctrine, standards, and reform | Batched drilling operations should only be undertaken after careful assessment of the special risks which such operations give rise to; well control must be maintained during the course of batched drilling operations. |
REC177-3341 | 32 - Doctrine, standards, and reform | The definition of ‘good oilfield practice’ in the OPGGS Act is unduly narrow. The current definition is incapable of application except where things ‘are generally accepted as good and safe’. The definition should be amended such that ‘good oilfield practice includes…’. |
REC177-3370 | 32 - Doctrine, standards, and reform | Environment plans and OSCPs should be made publicly available as a condition of approval of proposals under the OPGGS Act, and should clearly set out Scientific Monitoring requirements in the event of an oil spill. |
REC177-3277 | 32 - Doctrine, standards, and reform | The concept of ‘good oilfield practice’ should be supplemented by the requirement to incorporate into WOMPs non‐exhaustive minimum compliance standards in relation to well control: for example, stipulations as to when BOPs and/or well control systems must be in place and when they can be removed and minimum barrier requirements (a number of other factors that should be stipulated are outlined in other recommendations below). |
REC177-3309 | 32 - Doctrine, standards, and reform | If performance of barrier installation is outsourced by a licensee, the contractor (for example, the cementing company) should be engaged on terms which clearly require the provision of expert advisory services by the contractor with respect to barrier integrity. |
REC177-3327 | 32 - Doctrine, standards, and reform | Information relevant to well control must be captured and communicated within and between licensees and rig operators (and relevant third party contractors), in a manner which ensures it comes to the attention of relevant personnel. In particular, protocols should be developed to ensure that changes in shift and hitch do not operate as communication barriers. |
REC177-3352 | 32 - Doctrine, standards, and reform | The regulator, rather than the responsible Minister, should be given the power to direct an operator to use a particular rig for the purpose of well control operations, if appropriate in the circumstances, and the power should be used in the future if that rig is the best option available. This would necessarily involve the operator fully compensating for the use of the rig and any other associated costs. The Inquiry suggests that this power could be invoked and given effect as a condition of an operator’s licence. |
REC144-3387 | 25 - Inquiry, audit, lessons management and after action review | In order that the ACT public can be reassured about the project management and financial planning in relation to the Fairbairn site as a proposed centralised accommodation facility for emergency services, the Auditor-General undertake a review of the project from a financial probity and project management perspective. |
REC177-3296 | 32 - Doctrine, standards, and reform | Use of single strings of intermediate casing to penetrate hydrocarbon bearing zones should be carefully risk assessed. Multiple strings of intermediate casing have the advantage of isolating lost circulation zones and sealing off anomalous pressure zones. If intermediate casing is set in a hydrocarbon zone it should be treated as production casing. |
REC177-3315 | 32 - Doctrine, standards, and reform | PCCCs should be installed in a timely manner (for example, to prevent corrosion in the MLS apparatus). Non‐installation in order to park a BOP is not acceptable. |
REC177-3336 | 12 - EM agency and authority | Achievement and maintenance of well control should be written into the job responsibilities of key personnel, at every level up to and including CEOs. That is, a functional line of accountability for well control must exist up to, and including, CEOs. |
REC177-3361 | 32 - Doctrine, standards, and reform | The National Plan should be revised to ensure that it fully comprehends environmental matters and that it recognises the importance of the prompt implementation of Scientific Monitoring to facilitate the assessment of the environmental impacts of an incident. |
REC177-3302 | 32 - Doctrine, standards, and reform | Industry, regulators, and training/research institutions should develop standards that address best practices for cementing operations (including liaising, as appropriate, with overseas regulators) with a view to overcoming problems which can effect the integrity of cemented casing shoes, annulus and cement plugs. |
REC177-3320 | 32 - Doctrine, standards, and reform | Any pro‐formas used by licensees, rig operators and contractors for recording information about installation of barriers should explicitly provide for ‘exception reporting’, that is, the form should include provision for recording any unforseen or untoward events which occur in the course of installation. |
REC177-3340 | 32 - Doctrine, standards, and reform | To better ensure that ‘risks’ are identified and managed in accordance with sound engineering principles and good oilfield practice, it is recommended that regulation 25(1)(a)(i) and (2)(a)(i) of the Management of Well Operations Regulations, be reworded as follows: ‘A titleholder must not commence / continue a well activity if…a well integrity hazard exists in relation to the well’. |
REC177-3368 | 32 - Doctrine, standards, and reform | The regulatory framework should provide that in respect of all activities in Commonwealth waters: |
REC177-3276 | 32 - Doctrine, standards, and reform | WOMPs should be comprehensive and freestanding, rather than an overarching document cross‐referencing many other documents (although the Inquiry also recommends a freestanding well control manual; this should be a guide to rig and onshore personnel on good oilfield practice). |
REC177-3308 | 32 - Doctrine, standards, and reform | Volumes of cement used in connection with barrier installation should be calculated with the assistance of a pro‐forma which records all relevant baseline data, which should be verified by onshore personnel. |
REC177-3326 | 32 - Doctrine, standards, and reform | Prior to commencement of drilling operations, senior representatives of the licensee and rig operator should exchange certificates to the effect that their respective key personnel and contractors have been informed in writing of agreed well control arrangements. |
REC177-3350 | 32 - Doctrine, standards, and reform | The recommendations of the Inquiry in relation to suitable ways of achieving well integrity contained in Chapter 3 be included in a guidance manual that is issued for the assistance of industry and regulators. |
REC177-3378 | 25 - Inquiry, audit, lessons management and after action review | In view of the numerous well integrity problems in all of the Montara Oilfield wells, the Minister should commission a detailed audit of all the other offshore wells operated by PTTEPAA to determine whether they too may suffer from well integrity problems. |
REC177-3292 | 32 - Doctrine, standards, and reform | Licensees should be subject to an express obligation to inform regulators of the proposed removal of a barrier, even if they consider that well integrity is not thereby compromised. The information should be provided by way of special report, rather than included in a standard reporting document (such as a DDR). The information provided should include risk assessment details. Removal of a barrier should not take place without prior written approval of the relevant regulator(s). |
REC177-3314 | 32 - Doctrine, standards, and reform | Secondary barriers (including PCCCs) should only be installed, tested, and removed with a BOP in place unless a documented risk assessment indicates that well control can be maintained at all times. |
REC177-3335 | 32 - Doctrine, standards, and reform | Licensees, rig operators and relevant third party contractors should develop well control competency standards for key personnel in other entities involved in well control operations. |
REC177-3359 | 32 - Doctrine, standards, and reform | The National Plan should be reviewed to clarify the arrangements to apply in Commonwealth waters regarding key roles and responsibilities, including in relation to the ESC, in the event of an oil spill. This should also address any necessary training required. |
REC177-3301 | 32 - Doctrine, standards, and reform | The industry standard of two barriers should be replaced with the concept of ‘two or more barriers’ as a minimum standard. A minimum standard when operations proceed normally should never be regarded as a sufficient standard in other circumstances. |
REC177-3319 | 32 - Doctrine, standards, and reform | Drilling programs dealing with barrier installation should incorporate relevant aspects of manufacturer’s instructions. |
REC177-3339 | 32 - Doctrine, standards, and reform | The Inquiry supports the objective (rather than prescriptive) approach to regulation now followed in Australia. However, the pendulum has swung too far away from prescriptive standards. In some areas relating to well integrity there needs to be minimum standards. |
REC177-3367 | 32 - Doctrine, standards, and reform | Procedures and accountabilities should be established to ensure, in the event of a future incident, that: |
REC177-3275 | 32 - Doctrine, standards, and reform | Well Operations Management Plan (WOMPs) submitted by licensees to the regulator(s) should continue to be the primary framework document for achieving well integrity. |
REC177-3307 | 32 - Doctrine, standards, and reform | Any indication of a compromised cemented shoe which cannot be resolved with a high measure of confidence should result in the installation of additional well control barrier(s). |
REC177-3325 | 32 - Doctrine, standards, and reform | Relevant personnel from licensees and rig operators should meet face to face to agree on, and document, well control issues/arrangements prior to commencement of drilling operations. Well control should be regarded as a so‐called SIMOP to signify its critical importance to both licensees and rig operators, and to ensure that they each take responsibility for achievement and maintenance of well control. |
REC177-3344 | 25 - Inquiry, audit, lessons management and after action review | There should be a review to determine whether it is appropriate to introduce a rigorous civil penalty regime and/or substantially increase some or all of the penalties that can be imposed for breaches of legislative requirements relating to well integrity and safety. |
REC177-3377 | 32 - Doctrine, standards, and reform | The Minister consider legislative amendments to the OPGGS Act which make clear that |
REC177-3284 | 32 - Doctrine, standards, and reform | Memoranda of Agreement should be entered into between operators in relation to provision of emergency assistance in the event of blowouts. |
REC177-3313 | 32 - Doctrine, standards, and reform | Barriers should not be installed or removed off‐line. The derrick should be located over a well at the time of removal and installation of any barrier. This will enable more decisive action to be taken in the event a problem arises. |
REC177-3334 | 32 - Doctrine, standards, and reform | Licensees, rig operators, and relevant third party contractors should develop well control competency standards for their key personnel. Wherever possible, the competencies of key personnel should be benchmarked against their roles and responsibilities. |
REC177-3355 | 32 - Doctrine, standards, and reform | The Inquiry also supports Bills and Agostini’s recommendation: ‘…in relation to safety case development and compliance overall, that NOPSA revise its approach to interacting with operators prior to the safety case assessment process and subsequently direct more resources into its advisory functions. We further recommend that NOPSA develop and implement a formal plan for supporting and guiding each operator prior to safety case acceptance, as well as for ongoing compliance with that safety case, recognising the unique experience, capabilities and assessed risk of that operator. Each plan needs to include advice, education and liaison meetings with the operators. The plan needs to be continuously reviewed and reassessed based on the latest information, including the interaction with the operator’. |
REC177-3300 | 32 - Doctrine, standards, and reform | Licensees and rig operators should install an additional barrier whenever (i) there is any real doubt as to the integrity of any barrier; (ii) whenever the risk of flow from a reservoir increases materially in the course of operations; and (iii) where the consequences of a blowout are grave (for example, for reef systems or shorelines). |
REC177-3318 | 32 - Doctrine, standards, and reform | Manufacturers should be consulted about how to address non‐routine operational problems affecting their well control equipment. |
REC177-3338 | 12 - EM agency and authority | Licensees and rig operators should be astute in ensuring that corporate systems and culture encourage rather than discourage raising of well control issues. For instance, do performance bonuses or rewards actually encourage or discourage reporting of issues? Is there a system in place to enable anonymous reporting of well control concerns? What whistleblower protections are in place? |
REC177-3366 | 32 - Doctrine, standards, and reform | The National Plan should be reviewed: |
REC177-3306 | 32 - Doctrine, standards, and reform | It should be standard industry practice to re‐test a cemented casing shoe (that is, after WOC) whenever the plugs do not bump or the float valves apparently fail. Standard industry practice should require consideration of other tests in addition to a repeat pressure test. |
REC177-3324 | 32 - Doctrine, standards, and reform | The mere fact that the rig is over the platform should not be regarded by licensees or regulators as sufficient justification for reliance on only one barrier. The default position should be that producible wells are shut‐in when a rig is moved on and off a platform, or when a drilling unit is moved between wells on a platform. |
REC177-3343 | 32 - Doctrine, standards, and reform | The OPGGS Act should be amended to allow for a power to suspend a petroleum production licence (in addition to the current power to cancel a licence or suspend its conditions). |
REC177-3374 | 25 - Inquiry, audit, lessons management and after action review | The Minister should, as the JA for the offshore area of the Territory of Ashmore and Cartier Islands, undertake a review of PTTEPAA’s permit and licence to operate at the Montara Oilfield. |
