Session 3: Lessons Learnt – Pre-Decommissioning Preparation
Session Chairpersons Shahida Abdullah, PCPP OC Sdn Bhd (Pertamina); M Redzuan A Rahman, PETRONAS

Over 2,000 platforms have been decommissioned in the Gulf of Mexico’s shallow water. The benefits of pre-planning have been experienced and unfortunately when proper planning was not carried out we have observed consequences. Case studies will be presented with actual platform locations, conditions, photographs, and resources used, to illustrate the benefits of proper planning and lessons learnt.

15:30 - 16:00
16:00 - 18:30
Session 4: Rigless Options for Dry Tree
Session Chairpersons Nurul Ezalina Hamzah, PETRONAS; Darwin Tangkalalo, PCPP OC Sdn Bhd (Pertamina)

Many alternatives for wells P&A and platform decommissioning are being explored as one of the efforts to optimise the total operation cost. Methods such as offline rigless intervention using coiled tubing, E-line and RMS (rigless marine spread) are chosen over big rigs due to more simplified and cost effective operations. This session will provide an avenue for participants to discuss methods for rigless wells P&A and platform decommissioning that are currently available in the market. Participants will also share best practices and experiences from past operations utilising rigless methodology. 

18:30 - 22:00

08:30 - 10:30
Session 5: Unconventional Solutions
Session Chairpersons Nik Aman Manaf, PETRONAS; Redzuan Abd Rahman, PETRONAS

Alternative facilities removal approaches considering technologies that can reduce the offshore duration should be explored especially in the current oil price economy as the conventional decommissioning operation involving Heavy Lift Barges incur a significant cost. The methods on optimizing execution strategies and minimizing the decommissioning project cost will be covered in the session as well as the applications of unconventional technologies and approaches that has proven to improve operational efficiency of well P&A and facilities removal. In reducing the cost of wells abandonment, operators and regulators are improving the P&A performance including completion removal, annular cementation verification and permanent P&A barrier placement while service providers are developing the tools to increase the efficiency.

10:30 - 10:45
10:45 - 12:45
Session 6: Case Studies – Solutions to Alternative Decommissioning Options
Session Chairpersons Md Yusoff Mohamad Noor, Sapura Energy Bhd; Noor Amila Wan Zawawi, Universiti Teknologi PETRONAS

Alternative decommissioning options such as reefing and reuse have indeed benefited operators and other sea users. Proper implementation of alternative decommissioning options through collaborative efforts by both operators and service providers have proven the viability and sustainability of such options for the future. In the past, issues surrounding alternative decommissioning options were merely academic exercises which were later discarded during the executive stage. Engineering solutions for issues such as reefing have enhanced the confidence level of stakeholders and other key decision makers to opt for these options. Coupled with mastery in heavy lift engineering and integrated engineering solutions, alternative decommissioning options have become an ideal way forward in the emerging offshore platform decommissioning sector.

12:45 - 13:45
13:45 - 15:45
Session 7: Managing Well Integrity, Risk and HSE
Session Chairpersons Seyri Anuwa Jahari, Vantage Well Services

This session will cover the operator/contractor view on well integrity with uptrend of well decommissioning requirement and activities. The integrity stand point shall cover ageing well conditions, method of assessments, and tool/technique/solution required to make it possible to perform the final operation on the well. Next, it will take participants to the most critical part of well decommissioning which is the evaluation, understanding, and managing of risks and HSE – implementing permanent/near-permanent solutions with a strong emphasis on safety. Focus will be on cementing techniques, materials and tools. Finally, what will be the benefit of going low-cost now versus future remedial cost.

15:45 - 16:00
16:00 - 17:30
Session 8: Decommissioning Execution Lesson Learnt
Session Chairpersons Noor Amila Wan Zawawi, Universiti Teknologi PETRONAS

This session will focus on lesson learnt from assets that had underwent decommissioning projects. As the oil and gas assets in SEA becomes more mature, more facilities will begin implementing and executing decommissioning strategies most beneficial for them. As this happens, new organisations will be exposed to the unavoidable phase of the decommissioning process. With any new activity, there are difficult times and a learning curve for new participants.
Decommissioning activities have been performed since the early 1980’s and over time, experience has been gained. Historically, many mistakes were made but executions were improved over time. In reality, an organisation will only plan and implement a decommissioning project once with limited experience, hence the industry must learn from the experience of past projects in the decommissioning field. In view of this, it is timely to open up information exchange amongst operators, service providers and regulators on lessons learnt during the planning and implementation of past and ongoing decommissioning projects.

17:30 - 18:00
