Rec-ID | Code | Recommendation |
---|---|---|
REC177-3291 | 39 - Disaster Risk Management | Removal of a barrier must be the subject of consultation between licensees and rig operators prior to removal. A proper risk assessment should be carried out and agreed upon, and documented in writing before removal. Joint written certification as to the appropriateness of removal should take place before removal. Senior onshore representatives of stakeholder entities should be involved in that certification process. |
REC177-3303 | 29 - Operational Health and Safety | Tracking and analysis of cementing problems/failures should occur to assess industry trends, principal causes, remedial techniques and so on. |
REC177-3281 | 29 - Operational Health and Safety | Wellbore gas bubbling should be regarded as a trigger for independent review of well integrity. Industry and regulators should identify and document other triggers. |
REC177-3289 | 39 - Disaster Risk Management | The use/type of barriers (including any change requests relating thereto) must be the subject of consultation between licensees and rig operators prior to installation. A proper risk assessment should be carried out, agreed upon, and documented in writing before installation. Joint written certification as to the appropriateness of the use of particular barriers should take place before installation. Senior onshore representatives of stakeholder entities should be involved in that certification process. |
REC177-3299 | 29 - Operational Health and Safety | Regulatory approval to rely on only one barrier should not be given unless (i) a proper risk assessment is carried out; (ii) exceptional circumstances exist; and (iii) risks involved are reduced to ‘as low as reasonably practicable’. The default position must be that well integrity must be assured. |
REC177-3279 | 29 - Operational Health and Safety | Well construction and management plans, and drilling programs, should include provision for testing and verifying the integrity of all barriers as soon as practicable after installation. |
REC177-3288 | 29 - Operational Health and Safety | As soon as a risk of barrier failure arises, no other activities should take place in the well other than those directed to removal of the risk. |
REC177-3295 | 29 - Operational Health and Safety | Wells drilled into hydrocarbon zones should be treated as live wells, with the potential to blowout unless a documented risk assessment establishes otherwise. |
REC177-3278 | 29 - Operational Health and Safety | Well construction and management plans should include provision(s) for reviewing the integrity of barriers at safety‐critical times or milestones, such as (i) prior to suspension involving departure of the rig from the platform; (ii) prior to re‐entry of a well after suspension; (iii) prior to removal of any barrier. |
REC177-3356 | 39 - Disaster Risk Management | The regulator should pre‐assess and review in a generic sense, and in conjunction with the offshore petroleum industry, available options for well control in the event of a blowout. Being ‘match fit’ in this sense will enable a quicker and more effective response in terms of safety assessment, and will ensure that expectations of both operator and regulator are more readily aligned. |
REC177-3286 | 39 - Disaster Risk Management | Problems which arise in the course of installing barriers must be the subject of consultation between licensees, rig operators, and contractors (if used). A proper risk assessment should then be carried out and remedial steps (including further testing/verification) should be agreed upon, and documented in writing before the performance of remedial work whenever practicable. Joint written certification as to resolution of the problem should take place before resumption of drilling operations. Senior onshore representatives of stakeholder entities should be involved in that certification process. |
REC177-3294 | 29 - Operational Health and Safety | Perceived time and cost savings relating to any matters impacting upon well control should be subjected to rigorous safety assessment. |
REC177-3330 | 39 - Disaster Risk Management | Decision‐making about well control issues should be professionalised. Industry participants must recognise that decision‐makers owe independent duties to the public, not just their employer or principal, in relation to well control. Risk management in the context of well control needs to be understood as an ethical/professional duty. Self‐regulation contemplates self‐regulation by the industry, not just by individual licensees and operators. |
REC177-3285 | 39 - Disaster Risk Management | Pre‐drilling assessments should include a risk assessment of the worst‐case blowout scenario. |
REC177-3293 | 29 - Operational Health and Safety | If a dispute arises between a licensee and a rig operator in relation to a well control issue, and is not resolved between them, the matter must be raised with the relevant regulator before discretionary operations proceed. |
REC177-3321 | 29 - Operational Health and Safety | Careful consideration must be given to equipment compatibility as part of well construction design. |
REC177-3282 | 29 - Operational Health and Safety | If a risk assessment or compliance review is triggered by the happening of a predetermined event, specific consideration should be given to whether a ‘hold point’ should be introduced such that work must cease until the problem is resolved (and the subject of appropriate certification). |
