More than 200 offshore fields comprising of over 1,500 platforms and 7,000 wells are expected to curb production by 2030, signalling an urgent need for clarity in regard to decommissioning regimes.
Despite the task size, only a handful of southeast Asian countries are involved in decommissioning activities, making their overall experience limited. Adding to this challenge, are the following three region-specific issues:
Expro Group Holdings N.V., a leading energy services provider, has announced its financial and operational results for the first quarter of 2025, revealing a revenue decline but highlighting technological advancements and new contract wins.
The company reported revenue of $391 million for the three months ended 31 March 2025, down 11% from US$437mn in the fourth quarter of 2024, reflecting seasonal and market challenges.
The US$46mn revenue decrease was driven by reduced activity in the North and Latin America (NLA), Europe and Sub-Saharan Africa (ESSA), and Asia Pacific (APAC) segments, though modestly offset by higher activity in the Middle East and North Africa (MENA) segment.
Consistent with historical trends, the winter season in the Northern Hemisphere and budget cycles of national oil company clients negatively impacted revenue and profitability.
“While 2025 is expected to be a transition year for the energy services industry, the outlook for oil and gas investment and Expro remains quite compelling for the rest of the decade, so we are cautious about the near-term and more bullish over the medium- to long-term,” said Michael Jardon, CEO.
“That said, we will size our support structure, capital expenditures and other investments accordingly, so cost and capital discipline will be key themes at Expro until we have better clarity around the direction of international and offshore markets, and the timing of deepwater projects that we expected to be sanctioned in the second half of 2025 and into 2026.”
Expro showcased its commitment to advanced technology with notable deployments in Q1. The company successfully introduced its CENTRI-FI™ consolidated control console in Indonesia, enabling fully integrated tubular running services (TRS) operations from a single tablet, reducing personnel presence on the rig floor.
In the APAC region, Expro secured significant contracts, including a three-year deal worth over US$15mn to provide combined e-line cased hole and slickline services across 315 wells.
Additionally, a two-year contract valued at over US$8mn was signed in Brunei to deliver well metering services, leveraging advanced solutions like QPulseTM, Sonar Meter, and Multiphase Flow Meters.
This agreement, which began in February 2025, strengthens Expro’s role in optimising client production through precise well flow measurement.
However, APAC revenue fell 19% to $51 million from US$62mn in Q4 2024, driven by reduced subsea well access, well flow management, and well construction activity in Australia, as well as lower well intervention and integrity work in Brunei and Malaysia.
Segment EBITDA for APAC was US$11mn, or 21% of revenues, down from US$15mn, or 25% of revenues, in the prior quarter, due to lower activity and an unfavourable activity mix.
The Asia Pacific (APAC) offshore well intervention market is witnessing significant growth, given the advancements in technologies that are capable of boosting operational efficiency while reducing operator costs.
The future scope of the APAC Well Intervention Market points towards further expansion as exploration and production (E&P) activities in the region continue to thrive. The integration of automation and digitalisation in well intervention processes is expected to play a major role in driving market growth. Moreover, rising offshore production activities, especially in countries with untapped hydrocarbon reserves, are projected to offer lucrative opportunities for well intervention services.
Environmental regulations and a focus on sustainable production will also influence the adoption of advanced technologies and efficient well management practices. This evolving market landscape presents ample growth potential for stakeholders in the APAC Well Intervention Market in the years to come.
A number of technologies and equipment have been developed towards the drilling and completion of deep and ultra-deep wells.
This technology is developing towards composite bit, special-shaped tooth PDC, adaptive bit, intelligent bit, electric drill, real-time optimisation and non-contact rock breaking.
This technology is developing towards higher efficiency, whole process clean and environmental protection, intelligence and recycling; ultra-high temperature, extremely low temperature, nanometer, strengthening borehole wall materials and intelligent treating-agents will occur; and the integrated lost circulation resistance and plugging of malignant thirsty formations containing vugs or fractures will develop towards online performance measurement and control, automatic closed-loop solid control and automatic mud preparation system.
This technology is developing towards operation automation, information, intelligence and whole life cycle control of cementing process; cementing materials are developing towards ultra-high temperature, functionality, safety, environmental protection and adaptability; and cementing tools are developing towards high stability and high reliability under complex process conditions.
Coiled tubing operation is developing towards well logging, cementing, completion fracturing, downhole operation integration and deep ultra-deep layers, while coiled tubing drilling is developing towards intelligent measurement and control while drilling and closed-loop steering drilling
Removing abandoned offshore platforms are a major hassle, but converting these ageing infrastructure into reefs are an efficient and eco-friendly way to tackle this issue.
In the Asia-Pacific (APAC) region alone, there are more than 2,500 platforms that are awaiting decommissioning in the coming decade. Removing these huge structures not only take time, but is also likely to disrupt marine life. The rigs-to-reefs movement was introduced as a potential solution, with several countries in the APAC region including Thailand and Malaysia implementing these programmes successfully.
These platforms boost biodiversity by offering shelter, breeding grounds and feeding areas for marine organisms like fish, corals and invertebrates, with their metal frames in particular, being a key habitat to numerous marine communities.
Despite its advantages however, reefing does not come without risks. For example, several questions have been raised about the impact of these structures on natural marine patterns, migratory species and surrounding habitats. Moreover, regulators are often hesitant about adopting reefing programmes due to concerns surrounding long-term liability and public trust.
In order to tackle these issues, environmental agencies have there began monitoring these artificial reefs to keep a check on marine health. On the whole, reefing has received mixed reactions. While some have called this as a ‘creative problem-solving’ initiative, others have accused the oil and gas industry of using the technique as a way of stepping aside from taking environmental responsibility.
As reported by Earth.org, this approach however has a promising future, as it balances financial realities with sustainability.
Oilenco Ltd has announced the appointment of Paul Vettese as its new Business Manager for the Asia Pacific region.
Paul brings over 25 years of oil and gas experience to the role, including a decade spent leading sales teams for a global well intervention services provider in Asia Pacific. His extensive background makes him well-positioned to support Oilenco’s strategic growth and regional development plans.
Oilenco designs, engineers, and manufactures specialised downhole tooling to support oil and gas operations worldwide. Its comprehensive portfolio of well intervention solutions is designed to help operators reduce operational time and costs. The company’s innovative solutions are used globally across various offshore assets to enhance well access, intervention, and recovery operations.
In his role, Vettese will lead the development and execution of Oilenco’s business strategy across Asia Pacific. He will oversee the company’s regional direction and growth initiatives, drive new business opportunities, and strengthen relationships with existing clients throughout the region.
Blair McCombie, Operations Director, remarked, "The company is entering an exciting phase of growth, with clear ambitions to expand internationally. With Paul joining the team, we look forward to strengthening our presence across Asia Pacific and expanding our global footprint."
“Having spent the past decade leading sales across the Asia Pacific region, I’ve developed a deep understanding of the market dynamics, client expectations, and the technical challenges operators face. I’m excited to bring that regional insight and network to Oilenco, and to play a key role in expanding the company’s footprint by aligning our innovative solutions with the specific needs of customers throughout Asia Pacific,” added Paul.
Decommissioning activities have been limited in southeast Asia, with only a handful of countries being able to point to any decommissioning work in the last 20 years and the challenge has become tougher due to three key issues.
There is a general inconsistency regarding the approach to international conventions relevant of the decommissioning of offshore installations. International treaties do not have a force of law in every signitory country and the approach taken is inconsistent across the region. Domestically, the decommissioning requirements for southeast Asian nations may vary, depending on various factors. For example, in Indonesia, the implementation of Oil and Gas Law No 22 of 2001 meant that every production sharing agreement (PSC) must contain provisions with respect to post-operation obligations. Another example is Thailand, where the PSC contractor is expected to provide a security deposit, the value of which is approved by the Director General.
In each case, identifying the entity with liability for decommissioning is not a necessity. New legislation with respect to decommissioning may have an impact on the older concession agreements, PSCs or risk service agreements, subject to the terms of each relevant agreement, and whether the legislation has retrospective effect. In practice, they often lack clarity. There are a many such development agreements or arrangements between States or NOCs and oil and gas companies. However, there is no standard form of agreement; these are usually bespoke agreements, subject to different rules and covering different activities. Unless they are clear on decommissioning liabilities at the end of the JDA term, they would likely give rise to additional difficulties.
Since southeast Asia's oil & gas industry is immature when compared to other areas, there arise certain challenges that may not be the case in other areas. A lack of experience is often related to a lack of understanding of the decommissioning cost. Despite an operator or contractor contributing to a decommissioning fund, it is unlikely that the fund would be adequate.
To help the world transition to net zero, decommissioned oil and gas platforms can be repurposed into green energy hubs.
This includes offshore rigs for carbon capture and storage or storing and transporting hydrogen, a type of sustainable fuel that doesn’t emit carbon when it is burned. A report published on the World Economic Forum suggested using legacy oil platforms to produce green hydrogen, which is generated using renewable energy.
Scientists have said that resusing depleted oil and gas wells would allow operators to access geothermal heat in hot rock formations, eliminating upfront costs of drilling new wells and potentially making the technology more appealing to the industry.
Moreover, researchers have suggested that repurposing depleted oil and gas wells may significantly help mitigate potential environmental impacts of abandoned wells and allow operators to access geothermal heat in underground rock formations. It also provides new job opportunities in areas with rich energy industry traditions.
According to Arash Dahi Taleghani, professor of petroleum and natural gas engineering at Penn State, using existing wells can help maintain employment in the area while also allowing communities to be part of the energy future.
Borneo Oil Bhd, through its indirect subsidiary Borneo Oil (Sabah) Sdn Bhd (BOS), has been selected as a vendor by Petroliam Nasional Bhd (Petronas), Malaysia’s state-owned oil and gas giant, marking a significant step forward for local participation in Sabah’s energy sector.
Announced on 24 March, this development comes alongside a strategic collaboration with Intercontinental Strait Energy Technology Co Ltd (SETC), a leading Chinese drilling consultancy, to jointly bid for drilling and well intervention projects in the region.
The partnership, formalised 20 March, positions BOS and SETC—a Chengdu-based firm specialising in drilling optimisation, completion, and reservoir management—to compete for contracts that include consultancy, supervision, and services for drilling, workovers, stimulation, and real-time drilling monitoring. Borneo Oil emphasised SETC’s expertise as China’s largest drilling-management consultancy, highlighting the potential for this alliance to bolster Sabah’s oil and gas capabilities. This move aligns with Petronas’ broader efforts to ramp up operations in Sabah, a region critical to Malaysia’s energy ambitions.
Sabah, located on the northern tip of Borneo, is a cornerstone of Malaysia’s oil and gas industry, holding an estimated 1.5 billion barrels of oil (25% of the nation’s reserves) and 11 trillion cubic feet of gas (12% of total gas reserves). Petronas’ operations in Sabah centre on both sustaining production from mature fields and unlocking new potential through exploration and development. A key recent milestone is the signing of two production sharing contracts (PSCs) by Petronas Carigali Sdn Bhd (PCSB) for the SB412 and 2W blocks offshore Sabah. These blocks, encompassing nine fields, are part of the 2024 Malaysia Bid Round and leverage existing infrastructure like the Samarang Asam Paya and Erb West hubs.
While these PSCs focus on exploration and development, they set the stage for well intervention and maintenance—areas where vendors like BOS and partners like SETC could play a role. Petronas’ goal is clear: increase national production to two million barrels of oil equivalent per day (MMboe/d) to meet rising domestic demand, which hit 929,556 barrels per day in December 2023. Sabah’s deepwater and marginal fields are pivotal to this target, with intervention work like workovers and stimulations often required to optimise ageing assets.
Petronas’ ramp-up in Sabah extends beyond new blocks. The company’s Activity Outlook 2025-2027 forecasts 69 development wells in 2025 (up from 56 in 2024) and an average of 367 Facilities Improvement Plans (FIPs) annually through 2027. In Sabah, FIPs target rejuvenation and well maintenance—key intervention activities—for fields like Samarang, which produces 36,000 boe/d. This surge reflects Petronas’ response to natural decline and the need to maintain output, especially as Sabah’s mature fields age.
Further boosting local involvement, Petronas celebrated vendor growth in Kota Kinabalu on 23 January, with the Sabah government. Four Sabahan vendors, including those tied to “Integrated Well Continuity Services,” secured contracts for well interventions, abandonments, and workovers. This follows a trend of increasing local contract awards, which jumped from US$141mn (RM613 million) in 2021 to over US$460mn (RM2 billion) recently, with ambitious 2025-2027 targets to double Sabahan OGSE (Oil & Gas Services and Equipment) contracts and boost local job awards by 50-100%.
FourPhase, a specialist in solids and production performance within the oil and gas sector, has introduced The Observer, an advanced tool for real-time data capture and optimisation.
Already deployed in five operations across the Gulf of Mexico and the Norwegian Continental Shelf, the solution will soon be integrated across all FourPhase operations, enabling full-scale remote monitoring. As operators increasingly shift towards data-driven smart operations, the real-time insights provided by The Observer are proving invaluable.
Addressing key industry challenges
The Observer is designed to tackle three critical industry challenges: minimising downtime through data-driven decision-making, enhancing equipment maintenance efficiency, and accelerating the shift to remote operations. The system continuously captures real-time data to generate a live operational feed within FourPhase’s control centre while simultaneously populating online dashboards accessible to customers globally.
A key strength of The Observer is its robust security architecture. Adhering to a zero-trust security model, it complies with ISO 27001, 27017, and 27701 standards. The system establishes a secure connection to onshore operations via Starlink or similar technologies, providing a protected data transmission channel between offshore sites and onshore centres.
"Coupled with onsite remote operations, these capabilities are enabling a step-change improvement in offshore sand management. This opens up new opportunities for production optimisation and autonomy that were previously not possible," remarked FourPhase CEO Øyvind Heradstveit.
Leveraging a decade of data
Since 2013, FourPhase has been gathering solids management data, using it to simulate operational scenarios. By applying insights from real-world experiences rather than relying purely on theoretical calculations, the company has achieved an uptime exceeding 99.5% over the past decade. This extensive database allows for more accurate operational planning and improved performance predictions.
"As the energy industry operates with multiple, often competing, data-sharing standards, we’ve developed The Observer as a universal solution, integrating over 300 languages and protocols rather than locking into a single standard. This allows for real-time monitoring across diverse equipment—including Multiphase Flow Meter, the DualFlow Desander, Acoustic Sand Detectors, and client plant data—all simultaneously. The goal is to capture and process data instantly, empowering operators with real-time insights to make informed decisions," explained Jørgen Bruntveit, COO/CTO.
"Many competitors claim real-time monitoring, yet their systems often suffer from minute-long delays and cumbersome designs—some as large as a server rack. The Observer delivers true real-time monitoring in a form factor small enough to hold in one hand," added Bruntveit.
Although real-time condition monitoring and data-driven optimisation are now standard in many production-related workflows, sand management has largely remained dependent on labour-intensive legacy methods. This reliance has slowed the adoption of autonomous and low-manning platforms. By investing significantly in remote monitoring technology, FourPhase has closed this gap, ensuring The Observer enables full oversight across its entire fleet, including desanders.
Depending on the scenario, decommissioning oil and gas infrastructure can have potential negative impacts both on the economy and environment.
The top 10 research priorities were highlighted in a 2023 resarch paper which aid in making informed decommissioning decisions and enhance our understanding of its detrimental impacts.
Several contaminants are released into the environment during the decommissioning process. These include residual chemicals and reservoir constituents that can have significant negative impacts on marine life. As part of the risk assessment framework, all contaminants need to be carefully identified and assessed. Understanding the long-term, site-specific consequences of these contaminants is key to adequately assess risks from various decommissioning options including full removal, partial removal and leave in-situ decommissioning options.
A majority of risks associated with offshore decommissioning activities lack well defined baselines to measure potential impacts. In order to identify parameters that can be measured and monitored, a baseline needs to be predetermined, without which, the acceptability of decommissioning options cannot be assessed.
Due to a lack of knowledge and inconsistent or deficient regulatory guidance, the ongoing costs within current decommissioning decision-making processes are often overlooked. Liability frameworks should therefore be defined to determine the cost of full removal of structures, making remaining items safe, and returning the seabed to its pre-activity state. Costs involving alternative approaches such as the relocation of structures to a reefing location are also calculated by the industry.
To adequately assess and compare the social, technical and economic impact of decommissioning, the ecosystem services that are gained or lost from different decommissioning options need to be determined. While few marine-based environmental impact assessments (EIAs) are currently being integrated with ecosystem services, there has been limited success attributed to data gaps and the values have been ineffectively captured by ecosystem services. Hence, alternate schemes such as the Intergovernmental Platform for Biodiversity and Ecosystem Services (IPBES) and Nature's Contributions to People have been developed.
The long-term presence of offshore structures can have a positive and negative influence on ecological diversity, productivity and connectivity. For example, the presence of oil and gas structures in marine ecosystems can have negative consequences on the natural migration pathways of species that might be altered by the emission of sound, vibrations and light from structures. On the other hand, presence of these offshore infrastructures can also extend foraging opportunities of certain mobile species such as Australian fur seals. Long-term monitoring data should therefore be collected throughout the lifecycle of these installations to appropriately understand their impact on populations and connectivity.
Production and attraction mainly refer to whether fish are attracted to an artificial structure or whether it enhances fish production. When a new structure is installed, fish are rapidly attracted to the structure which can redistribute existing production. In some cases, fish production can significantly increase when infrastructures are installed in predominantly sandy, oligotrophic habitats since they provide additional hard substrata that can potentially increase the carrying capacity of organisms that utilise such habitats. Assessments should consider the duration of these structures in place and the extent of connectivity between fish populations on the structures and the broader ecosystem.
A range of research questions need to be addressed to assess the feasibility of re-using or re-purposing offshore structures. Firstly, it is important to understand the process of degradation of different materials beyond their initial design life. Secondly, the evolution of different seabed sediments and their impact on the stability and integrity of decomissioned offshore infrastructure need to be considered. Thirdly, the technology required to contain hazardous substances, monitor their impact on the ocean environment, pursue re-cycle, re-purpose and re-use opportunities for recovered infrastructure needs to be understood. Lastly, performing testing and validation is crucial to achieving confidence of the sector and inclusion in industry standards.
A review of stakeholder values regarding the benefits of offshore instrastructure identified both risks and opportunities. These involve a combination of social and economic values that are shaped by their knowledge frames. Since there is no one-size-fits-all, further research is required to understand the factors that influence the perceptions and attitudes of stakeholders towards decommissioning.
Although the decommissioning process contributes minimally to greenhouse gas (GHG) emissions in comparison to its full cycle, it still needs to be evaluated in regard to its total contribution to the global goal of reaching net zero emissions by 2050. It is also important to highlight the positive contributions of these structures such as the carbon sequestration potential of marine ecosystems formed around these structures in situ. Qualitative analysis of all sources of GHG emissions sequestered should also be considered. A combination of all these analyses would result in a net-carbon footprint being identified for each decommissioning option.
While classifying research priorities into disciplines is necessary to assess their impact, they are also in most cases, found to be transdisciplinary in nature.
