Simon Hough H S Executive,Universities Rod Smith Schlumberger. Purpose of the Oil Gas UK Guidelines,Scope and Style of the Guidelines. Document Good Industry Practice to help Industry meet. the requirements of UK legislation and avoid a loss of. well integrity, Written in a style designed to encourage discussion. Operators do not have to follow the Guidelines but. should be prepared to justify how their approach reduces. risk to as low as reasonably practicable, Relevant to all wells and well operations for the purpose. of exploiting naturally occurring hydrocarbons onshore. and offshore, Focus on typical wells standard operations Reference.
existing standards and guidelines rather than creating. Address HSE guidance relating to well integrity including. the Well Construction Standards Include guidance on. roles and responsibilities,As Low As As Low As Reasonably. Reasonably Practicable,Practicable ALARP,Time Trouble. Reasonably practicable is a narrower term than physically possible a computation. must be made by the owner in which the quantum of risk is placed on one scale and the. sacrifice involved in the measures necessary for averting the risk whether in money time. or trouble is placed in the other and that if it be shown that there is a gross. disproportion between them the risk being insignificant in relation to the sacrifice the. defendants discharge the onus on them HSE Reference Edwards v National Coal Board 1949 1 All ER 743. http www hse gov uk risk theory alarpglance htm,Evolution ofofthe. the Guidelines,Guidelines,Issue 2 published in April Issue 3 published in.

Interfaced with the Norwegian Oil Gas Well Integrity Forum and confirmed that the. draft Issue 3 is consistent with the direction of Norwegian work. Interfaced with the OGP workgroup producing the ISO Standard for full life cycle well. integrity while this document is going through a 2nd ballot confirmed that there are no. significant gaps between the draft Issue 3 and the draft ISO document. Interfaced with UKOOG to incorporate requirements for shale wells with the intent of. simplifying the existing Shale Gas Guidelines to cross reference the Well Integrity. Guidelines,Guidelines Changes in Version 3 March 2016. Changes Issue 2 to Issue 3 1, Updated with most recent publications added references and added terms to glossary.
Updated to reflect recent changes in regulatory environment primarily SCR 2015. Updated text to reflect current terminology on barriers and make section more readable. Specifically updated definitions of pressure containment boundary well barriers number. of barriers types of well barrier concept of primary and secondary barriers Updated. sections on risk assessment and pressure testing, Updated section on risk assessment and references to recent industry practices and. Restatement of main well integrity issues for gas lift and guidance on mitigating these. Clarity on what wellhead components are required on the non active side of a wellhead. Guidelines Changes in Version 3 continued,Visual inspection of wells. Guidance on frequency of inspection,Pressure testing and topping up annuli. Updated guidance to include consideration of hydraulic fracturing. Barriers within wellheads, Guidance on pressure testing of void spaces in wellheads including safety advice. prior to testing and inspecting voids,Testing xmas tree valves.
Guidance on performance standards for workover and intervention pressure. control equipment including recent industry findings on closure times and the. effect of temperature fluid type and control line geometry. Non standard well types, Moved section on CRI wells to Section 14 Special Cases. Guidelines Changes in Version 3 continued,Review of degradation life extension. Completely revised additions include guidance on key elements of a. degradation management programme reference to creeping change and. examples of strategies for the management of degradation and well failure. Natural or induced seismicity as issue affecting well integrity. Guidance on considerations for risk of loss of integrity through geo mechanical. subsurface movement,Completion fluid as a barrier, Added paragraph to cover use of completion fluid as a barrier in case where. there is no flow potential for example when the well is open to an. impermeable formation such as shale prior to stimulation. Guidelines,Changes Issue Changes,2 to Issue 3 in Version3 3. Continued continued,Fluid pumping operations, includes guidance on hydraulic fracturing operations and specifically fracture.
containment and induced seismicity in alignment with UKOOG. Has now become Management of late life and end of life wells and contains. guidance on late life well management including definitions of shut in wells plugged. wells and temporary plugging for suspension of well operations and suspension of. well activity operation,Section 14 Special Cases, Now contains guidance on well integrity related aspects of multi lateral wells and. cuttings re injection wells,Appendix 2, Added appendix 2 which contains a definition of the WONS well descriptors. Guidelines Changes in Version 4,Changes Issue 2 to Issue 3 1. Work underway to determine what guidance can be provided on. Composite wraps, Use of well integrity reliability data and failure prediction. Well degradation and corrosion in annuli conductors surface. Sustained casing pressure,Gas storage wells, Process safety for wells including drilling and intervention.
Interface gap analysis with ISO 16530 1,BOPs following API standard 53. Welded casing,Other Well Well Integrity Issues,Relief well planning. Refresh the current Guidelines for issue in the first half of 2018 Address the. following legislative changes capping and edits to improve clarity. BOP Guidelines, Further to a gap assessment between the Guidelines and API Standard 53. proposal to utilise API standard 53 with any orphan requirements incorporated. into the Well Integrity Guidelines Accordingly the BOP Guidelines will be retired. when Issue 4 of the Well Integrity Guidelines are published in the 1st half 2019.

Well design, Develop a Terms of Reference to build upon the successful elements of the well. scrutiny sessions,Operational efficiency workgroup. Analyse data from 5 to 10 wells per Operator against some basic key. performance indicators and hold a workshop in August to extract best practices. which would then be shared at the October Wells Forum Initial focus is. primarily on reducing flat time,IADC Rig Audit initiative. IADC proposed development of a common rig audit protocol and sharing the. audit findings to avoid each operator independently auditing a rig The Wells. Forum put forward some potential issues with this approach IADC and OGUK. agreed to approach the UK Regulators to get their views and will revert with a. business case for the October Wells Forum,Level 5 Well Control Training.
5 companies including BP had responded to the OGUK request for views on. Level 5 The Wells Forum view was to support rather than duplicate work being. done by other bodies such as IADC OGUK agreed to engage with IOGP IWCF. and IADC to monitor progress and revert back to the Wells Forum if Forum input.
