P&A strategy, slot recovery planning, and post-abandonment barrier surveillance across 170+ legacy wellbores on the
Norwegian Continental Shelf — under NORSOK D-010 and Equinor internal governance.
• Full-lifecycle barrier integrity assessments across 170+ legacy wellbores — evaluating completion history,
barrier condition, and wellbore degradation to define abandonment scope and sequencing; delivered P&A
operations 33% under budget without compromising compliance or safety standards
• Develop fit-for-purpose P&A strategies for complex wells with legacy completions and non-standard barrier
configurations — including Bismuth Alloy barrier qualification and Section Milling/Casing Slotting programs
where conventional cement placement is not viable
• Design and technically verified Perforation, Wash & Cement (PWC) programs, ensuring permanent isolation
met NORSOK D-010 permanent plug requirements
• Conduct post-P&A barrier monitoring and integrity surveillance on abandoned wellbores; where barrier
degradation has been identified - design and execute well re-entries to restore permanent isolation to
regulatory standard
• Author well-specific barrier schematics, risk registers, contingency plans, and Detailed Operational Procedures
(DOPs); leading operational risk analysis meetings and author MOC documents for senior leadership and
Norwegian PSA
• Interface with subsurface, operations and maintenance teams to optimize slot recovery sequencing; verified
fluid/cement programs and reviewed BHA designs
• Capturing lessons learned and integrating into future programs, Wellcom updates, and DOPs — driving
continuous improvement across the P&A portfolio

End-to-end ownership of asset WIMS governance, SCP management, and well integrity contract management across a
multi-well PETRONAS offshore asset.
• Owned end-to-end governance of the asset WIMS — ensuring 100% compliance with PETRONAS regulations
through audits, barrier verification, and integrity incident management
• Defined MAASP, MAWOP, and MOP for all wells; monitored annulus pressure trending and managed SCP
diagnostic campaigns including bleed-off/build-up surveys, tubing integrity tests, and leak detection logging
• Led annual well integrity audits across 142 wells — achieved 100% closure of all critical findings within 90 days
through cross-functional action plans and disciplined follow-through
• Revised 3 asset-wide integrity procedures (Barrier Verification, SCP Management, PM/CM Maintenance) to
align with PETRONAS WIMS and internal requirements — adopted across the full asset
• Contract and budget holder for 7 well integrity and intervention contracts totaling USD 14M+; negotiated
improved terms achieving 7% cost savings without scope reduction
• Delivered monthly integrity dashboards and risk mitigation roadmaps to asset leadership and cross-functional
stakeholders

WIMS governance, SCP management, and P&A candidate assessment across ExxonMobils multi-field Malaysian
producing asset portfolio.
• Managed WIMS governance across a large multi-field portfolio — maintained 100% PETRONAS regulatory
compliance through WIMS audits, barrier verification campaigns, and integrity incident management
• Executed SCP diagnostic programs (bleed-off/build-up surveys, WHX seal tests, leak detection logging);
identified failed barriers and planned remediation in alignment with PETRONAS PPGUA
• Owned the Well Integrity assurance process — maintained all outstanding issues in WellView, ensured
resolution within PETRONAS WIMS frequencies, and prepared quarterly/annual integrity reports for senior
management
• Provided technical input to MPM-EVO/WIMG/AMIR regulatory submissions and compliance engagements
• Collaborated with drilling and wells teams on P&A candidate assessments — cementing, mechanical plug
programs, and wellbore isolation design — ensuring compliance with PETRONAS requirements and industry
standards

Maintained gas deliverability above DCQ/CDC through proactive well management and rapid sick-well diagnosis. Planned and executed intervention programs (workovers, wireline, slickline, coiled tubing); designed WSO programs and rate exclusion strategies for high sand producers.

• Implemented Gas Gun technology in an idle well — added 200 bopd to daily production from a well that
would otherwise have remained permanently shut in
• Evaluated artificial lift technologies (ESP, PCP, nitrogen lift, CT-deployed systems) for idle well reactivation;
integrated technical-economic assessments for investment decisions

Real-time production surveillance on oil and gas wells using PI Process Book and AVOCET; monitored water cut, sand production, and GOR trends to optimize well performance. Planned and executed annual data acquisition campaigns (PLT, PBU surveys, flowing gradient surveys). Contributed to 1, 000, 000 man-hours without a single lost-time incident across all Petrofac-operated assets.

Executed 60+ well tractor, stroker, and milling operations across Asia Pacific; led sand clean-out campaigns in PNG, Malaysia, and Thailand — restoring 3, 000+ bbls combined production from shut-in wells
Performed first-ever lubricator valve and profile milling operations for Brunei Shell Petroleum on wireline — 100% success rate, recognised as an industry first

• Led well integrity logging campaigns for ConocoPhillips, Brunei Shell Petroleum, and Petronas Carigali;
detected and permanently mitigated methane leaks from 1960s-vintage abandoned wells in South Sumatra
• Performed 25+ logging jobs across Peninsular Malaysia; mentored junior engineers and led technical sales
presentations across the region
