The end of 2024 saw the Centre of Decommissioning Australia (CODA) celebrate its third anniversary of serving as the region’s peak body for decommissioning, and the organisation intends to keep the momentum building during its fourth year of operation.
Francis Norman, CEO of CODA, shared his delight with the milestone achievement, stating, “Reaching our third anniversary is a proud moment for CODA. It reflects not only the strength of our partnerships but also the dedication and collaborative spirit of everyone in shaping the future of decommissioning in Australia.”
Over the three-year period, CODA has grown to become a 130+ partner organisation across the entire supply chain.
As the organisation remains committed to advancing the industry within Australian waters, CODA has conducted various studies and initiatives during its operational years. Those include:
The above initiatives have not only aided in advancing industry knowledge, but played a vital role in highlighting the importance of collaboration in addressing the complexities of decommissioning.
Norman concluded, “The work we’ve achieved together – delivering key studies, building industry resources, and fostering collaboration – has set a solid foundation for continued progress. I want to thank all of our partners and the Jobs, Tourism, Science and Innovation Department of the WA Government for their valuable support. Here’s to many more milestones ahead.”
The North Sea Transition Authority (NSTA) has highlighted the crucial nature of new technologies in improving and speeding up P&A operations in cementing the UK’s position as a world-leader in cost-effective decommissioning.
Over the last few years, smart technologies have been piloted in the UK Continental Shelf to help the sector build upon its reputation for innovation and cost-efficiency. Despite strong process, many more are still awaiting field trials.
Last month NSTA, along with the Net Zero Technology Centre, hosted a showcase event where more than 20 technology providers displayed their new technology to an audience of around 20 international operators. The event aimed to raise awareness of the technologies and encourage operators to facilitate more field trials every year.
Some of the showcased technologies included alternative materials with the potential to create barriers in the well, such as resigns, polymers and bismuth, and logging and perforating tools designed to make the P&A process more efficient.
In the UKCS, around 1,500 wells will be due for decommissioning between 2026 and 2030, presenting the industry a golden opportunity to test innovative P&A technologies to demonstrate how they can save operators time and money.
Not only do innovative technologies play an integral role in ensuring operators comply with their regulatory obligations in terms of decommissioning assets, but those technologies which prove successful will likely be in demand globally in areas such as Australia, Brazil and the Gulf of Mexico as the demand for decommissioning processes in those basins continues to rise.
Carlo Procaccini, Chief Technical Officer at the NSTA, said, “In the UK, we’re fortunate to have a supply chain which consistently produces ground-breaking technologies for offshore operations, including well decommissioning. However, the full potential of this innovation can only be unleashed if suppliers are given a chance to show what they can do in the field. With the current high volumes of well P&A activity, I encourage operators to offer field trials to progress innovation and make the most of the savings on offer.”
The decommissioning of offshore fields is no longer the final chapter in their lifecycle. Increasingly, these sites are being repurposed for carbon capture and storage (CCS), a key strategy in the global push to achieve net zero emissions by 2050.
By utilising depleted fields to store CO₂ beneath the seabed, operators can transform non-productive assets into environmental solutions, aligning with international climate commitments.
The International Energy Agency (IEA) highlights CCS as a crucial tool for reducing emissions from existing energy infrastructure, decarbonising hard-to-abate industries, and facilitating low-carbon hydrogen production. The technology has long been linked to enhanced oil recovery (EOR), with operators injecting CO₂ into reservoirs to boost extraction rates—a practice dating back to the 1970s.
Despite growing interest, the CCS sector faces economic and technical hurdles. The IEA reported a 35% increase in announced capture capacity and a 70% rise in storage capacity in 2023, bringing projected CO₂ capture to 435 million tonnes annually by 2030.
However, this remains well below the 1 gigatonne required to meet net zero targets. Analysts at Rystad Energy warn that many announced projects may not materialise due to economic feasibility concerns, a common critique of CCS. Additionally, the Center for International Environmental Law (CIEL) notes that many past projects have faced operational challenges or failures.
Nevertheless, government incentives are spurring investment. In the US, the Inflation Reduction Act of 2022 expanded the 45Q tax credit, offering US$85 per tonne of CO₂ permanently stored and US$60 per tonne for EOR, attracting new investors and developers to the sector.
“The sector is on the verge of a breakthrough,” said Benn Cannell, innovation director at Aquaterra Energy. “Trailblazing companies are now going through the steps needed to deliver CCS at scale.” As more projects move forward, the industry’s success will hinge on advancing technology, securing financial backing, and overcoming operational setbacks.

The Woodside-operated Shenzi field has undergone planned shutdown to approach integrity and reliability scopes
An unplanned outage also had to be addressed, after which a key well was brought to production in November 2024.
The Shenzi North project has been in production in the US Gulf of Mexico since September 2023. For optimised production, this two-well subsea tieback operates as an extension of the existing Shenzi infrastructure.
Situated approximately 195 km off the coast of Louisiana in the Green Canyon protraction area, the Shenzi assets comprise of the Caesar oil pipeline and the Cleopatra natural gas pipeline that form the main source of the several connecting pipelines that help the product reach onshore from the Green Canyon region. While the crude oil produced is consumed in Gulf Coast, the natural gas generated from the field is directed to the Cleopatra via a lateral pipeline that connects onshore to the Neptune processing plant in St Mary’s Parish, Louisiana.
Commenting on the project's notably short turnaround, Woodside CEO Meg O’Neill had said, "First production from Shenzi North shows how we are leveraging existing infrastructure to increase production and provide attractive returns from our Gulf of Mexico business.
"Taking the project from FID to first oil in 26 months is a great achievement. I commend the project team on safely bringing this resource into production well ahead of schedule.”
Enjoying a 72% interest, Woodside had discovered the Shenzi field in 2002, with first hydrocarbons production following in 2009. Besides Woodside, Repsol is a partner in the field with a 28% interest.
Gulf Coast customers benefit from more than 100,000 barrels of oil per day and 50 million standard cubic feet of gas per day that comes from the Shenzi field.
A well from the Mad Dog Argos that is part of the Mad Dog conventional oil and gas field situated 200km off the coast of Louisiana in the south-eastern Green Canyon protraction area, US Gulf of Mexico, has maintained production at the peak rate of ~130 kbbl/d, and is undergoing an infill injector well.
Argos is considered the driving force of the second phase of the Mad Dog project as it helped the brownfield site to reach a gross production capacity of up to 140,000 boepd. This semi-submersible platform has helped bp to boost production by atleast 20%. "Argos is key to our strategy of increasing our Gulf of Mexico production to around 400,000 barrels of oil equivalent per day by the middle of this decade,” said Ewan Drummond, Senior Vice President, Projects, Production and Operations.
An infill development well work has also began at Mad Dog A-Spar, besides a planned offshore facility shutdown.
A Spar is a subsea truss spar which processed Phase 1 of the Mad Dog project, with over 100,000 boepd transported to Ship Shoal 332B through the Caesar pipeline, followed by the Cameron Highway Oil Pipeline System, which further provides gateway to the US interior. More than 60 mn st cu/ft of gas, on the other hand, goes through the Cleopatra pipeline to finally reach the Nautilus Gas Transportation System into Louisiana.
While bp operates the Mad Dog field, Woodside holds a 23.9% interest in the project.

It was a widely successful 2024 for Petrobras as the Brazilian operator has reported it has achieved all of its production targets that were established in the 2024-2028+ Strategic Plan.
In total, oil and natural gas production reached 2.7 million barrels of oil equivalent (boed). Commercial oil and natural gas production reached 2.4 million boed and oil production was reported at 2.2 million barrels per day.
The operator set a new annual record for total own and operated production in the pre-salt, with 2.2 million boed and 3.2 million boed respectively, equating to 81% of the company’s total production.
Petrobras made significant headway in 2024, with one note-worthy project including the start-up of two new platforms: the FPSO Maria Quitéria, located in the Jubarte field in the Campos Basin; and the FPSO Marechal Duque de Caxias in the Mero field located in the Santos Basin pre-salt layer.
During the year, the FPSO Sepetiba platform, in the Mero field, reached its maximum oil production capacity after eight months of operation. The ramp-up of FPSO platforms partially offset the losses resulting from maintenance shutdowns and the decline in mature fields in addition to the impact on production due to unscheduled shutdowns determined by the ANP and the effects of the Ibama strike.
Another significant milestone of the year was the start of commercial operations of the Natural Gas Processing Unit (UPGN), located in the Boaventura Energy Complex, in November which has the capacity to process 10.5 million m3/day of gas through its first module.
The Australian government is seeking expert guidance to dismantle over 200 aging oil and gas structures set for decommissioning this year. The Department of Industry, Science, and Resources (DISR) has issued a call for technical specialists to oversee the process, ensuring compliance with environmental and regulatory standards.
With a wave of decommissioning ahead, Australia is preparing for large-scale offshore infrastructure removal. The Centre of Decommissioning Australia (CODA) projects significant activity between February and July 2025. The scope includes 41 platform wells, 34 subsea wells, 15 exploration wells, multiple production units, pipelines, and various subsea structures.
Strengthening regulations and industry oversight
The growing number of obsolete offshore installations has prompted a tightening of Australia’s regulatory framework. Amendments to the Offshore Petroleum and Greenhouse Gas Storage Act 2006 (OPGGS Act) have introduced stricter financial requirements, increased oversight on asset transfers, and implemented trailing liability measures—holding companies accountable long after operations cease.
CODA estimates decommissioning liabilities at approximately USD $40.5 billion, with well plug and abandonment (P&A) and pipeline removals making up the bulk of costs. In response, DISR has created a dedicated Decommissioning Branch, recruiting specialists to refine policies, assess risks, and align strategies with international best practices.
Positioning Australia as a decommissioning leader
Beyond environmental and financial safeguards, Australia sees an opportunity to build a competitive decommissioning industry. With an estimated $60 billion in offshore retirement costs over the next 30–50 years, the government is laying the groundwork for a domestic sector that could drive job creation, innovation, and expertise.
The National Offshore Petroleum Safety and Environmental Management Authority (NOPSEMA) is leading efforts to uphold safety and environmental protocols throughout the process. By establishing best-in-class decommissioning capabilities, Australia aims to not only manage its offshore legacy but also export its expertise to global markets, transforming a costly challenge into an economic opportunity.
A recent report on Offshore Oil and Gas Decommissioning by the Australian Academy of Technology Sciences and Engineering highlights the surge in the development and deployment of advanced technologies tailored to the decommissioning process.
The oil and gas industry has embraced a sector-wide digital transformation, with the benefits of enhancing worker safety, reducing environmental impacts, driving efficiencies and cutting costs. This transformation has enabled a reduction in the number of workers on offshore facilities, for example, thanks to increasing remote operations and increased automation. There is likewise scope for the decommissioning sector to undergo a similar transformation.
However the report notes that, while digital technologies are a key enabler for more efficient decommissioning practices, they need to be accompanied by the further development of physical technologies to advance decommissioning processes.
One key area of technological advancement highlighted is the use of robotics and autonomous systems for subsea infrastructure removal and dismantling. These technologies enable precise and controlled operations in challenging offshore environments, such as the Gulf of Mexico, reducing the need for human intervention and minimising safety risks. Automated cutting systems use robotics and advanced machinery to perform precise cutting tasks during the removal phase of decommissioning, for example ROVs equipped with cutting devices can be used to cut pipes into sections, facilitating pipeline removal, and swarm robotics for collaborative subsea monitoring, involving the use of multiple small, autonomous robots for collaborative monitoring tasks, can enhance efficiency and coverage in subsea environments. The integration of AI and ML algorithms is enhancing the predictive maintenance of decommissioning equipment, facilitating process optimisation, and improving cost-effectiveness.
Rigless P&A processes are being explored globally due to potential cost efficiency gains, improved environmental compliance and enhanced safety outcomes, the report notes. This approach enables safe pressure testing, providing a comprehensive understanding of individual well conditions, leading to safer and more cost-effective P&A interventions. In addition, alternative barrier technologies such as thermite plug technology, resin plugs and bismuth alloy play an important role in ensuring the integrity of decommissioned wells as attentions shifts towards more cost-effective, efficient and environmentally compliant decommissioning solutions.
Another technological development highlighted is the application of advanced sensing and monitoring systems, which can assess environmental impacts and support risk assessment during decommissioning activities. This includes autonomous and remote systems equipped with state-of-the-art sensors, as well as satellite imagery. These technologies are also being used to provide real-time data on areas such as water quality, marine life and ecosystem health, helping operators to make informed decisions about decommissioning strategies and mitigating potential environmental risks.
Circular economy principles are increasingly driving innovation, the report notes, particularly in recycling and reusing decommissioned materials. Advanced material separation technologies and processing methods can be used to recover valuable resources from decommissioned equipment and structures, contributing to resource conservation, and reducing waste.
As part of its promise to boost the competitiveness of its upstream sector while pursuing a sustainable future, PETRONAS will continue to prioritise its decommissioning responsibilities, directing its focus to accessing unused assets for potential repurposing.
The Malaysia-based operator has released its 2025-2027 Activity Outlook report, where it highlights the call to decommission the Sabah-Sarawak Gas Pipeline alongside 37 offshore facilities. PETRONAS’ three-year plan also includes the plugging and abandonment of 153 wells within the region.
The report states, “PETRONAS continues to explore innovative decommissioning solutions focusing on technologies, reuse/repurpose options, integrated multi-year execution approach for economies of scale, as well as identifying potential alternatives that can introduce cost compression. Thus, participation and collaboration are encouraging from all parties.”
PETRONAS’ report noted the importance of decommissioning matured assets in Malaysia’s upstream oil and gas industry as it is “essential to restore the area to a safe and environmentally stable condition.”
With that initiative at the forefront, in December 2024 the operator collaborated with the Department of Fisheries to launch the 10-year Malaysia Master Reefing Plan which outlines the potential for reefing in the region by spotlighting suitable candidates and locations to undergo the ‘rigs-to-reef’ operation: an initiative which stands as a popular decommissioning alternative in the Gulf of Mexico.
Alongside decommissioning, PETRONAS shares its outlook regarding upstream operations. In the short-term, the operator will focus on intensifying exploration activities and expediting appraisal programmes to sustain production and contribute towards Malaysia’s energy security. In the medium- to long-term, PETRONAS will continue to meet production targets and maximise shareholder value while decarbonising the value chain through innovation, technical deployment, and close collaboration with industry partners.
