Aker BP has renewed its alliance with SLB and Stimwell Services to boost oil output, extending the well intervention and stimulation alliance by five years.
In 2019, Aker BP, SLB, and Stimwell Services entered into a five-plus-five-year tripartite agreement to form the well intervention and stimulation alliance, aiming to accelerate and enhance oil production. On April 2, 2025, the three companies renewed this alliance, signing a new agreement at Aker BP’s headquarters in Fornebu, with all CEOs present at the ceremony.
The alliance has helped Aker BP meet production goals across its operated assets through close collaboration, digital innovation, and the use of advanced technologies. It has unlocked several industry milestones, including simultaneous operations using jack-up rigs, a reduction in locked-in barrels, and what Aker BP calls the world’s first autonomous intervention operation.
Karl Johnny Hersvik, CEO of Aker BP, commented, “Strategic partnerships are essential to shaping the future of our industry. At Aker BP, we remain committed to the alliance model, which creates value through long-term collaboration. It enables us to increase productivity, maintain world-class performance, and deliver oil and gas with low cost and low emissions. This is how we position ourselves as the E&P company of the future.”
According to Aker BP, digital workflows now handle planning and execution, resulting in improved productivity, reduced risks, and higher success rates. The alliance will maintain its focus on transforming offshore well intervention and stimulation over the next five years, with plans to deepen the integration between subsurface and operational teams, expand remote operations through Aker BP’s Integrated Operations Centre, and fast-track the adoption of new technologies.
Sami Haidar, Managing Director at StimWell Services, emphasised, “Stimulation has been critical in unlocking and increasing the recovery from tight reservoirs such as Valhall. During the last five years, the alliance working together managed to successfully develop very tight areas of the field, by using innovative technology which significantly reduced the execution time, and CO2 footprint and making it economic.”
The alliance is also expected to play a significant role in bringing wells online in Aker BP’s ongoing field development projects. A newly upgraded stimulation vessel will be deployed to optimise output from the new Valhall PWP wells, contributing meaningfully to the company’s future production.
The Gulf Cooperation Council (GCC) region that comprises the Arab countries will be welcoming a large class vessel by Gulf Marine Services (GMS), a provider of self-propelled, self-elevating support vessels to the offshore energy industry.
This is yet another contract for GMS that will be valid for a total of 142 days, whereby the vessel will be supporting critical offshore operations in the region.
The high market demand for offshore vessels has showered the company with its fourth contract win or extension this year.
"We are thrilled to secure this contract which once again reflects the confidence our clients place in GMS to deliver reliable solutions for their projects," said Mansour Al Alami, GMS Executive Chairman.
This follows GMS' last contract win in March for an additional vessel in the Middle East by a major regional client. It spanned an initial term including extensions of seven months.
This additional vessel, sourced to meet the demands of this project, will support a range of offshore operations, leveraging its advanced capabilities to deliver tailored solutions for various projects in the region.
"This award underscores GMS’s ability to source and provide customised solutions to our clients and demonstrates our flexibility in meeting current as well as future demand," Al Alami had said.

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.
The global well intervention market is projected to grow significantly over the next decade, as operators prioritise optimising output from existing oil and gas wells.
These services, which include everything from maintenance and repairs to production enhancement, play a vital role in extending the operational life of both onshore and offshore wells while reducing downtime.
Well intervention activities generally fall into two categories: light well intervention (LWI) and heavy well intervention (HWI). LWI includes smaller, cost-efficient operations such as wellbore cleaning and monitoring. HWI covers more complex work such as hydraulic workovers and large-scale repairs, often requiring advanced tools and specialised equipment.
This demand is largely being driven by a combination of factors. Global energy consumption continues to rise, encouraging more efficient use of existing resources. Many oil fields are reaching maturity, requiring targeted intervention services to extract remaining reserves. At the same time, technological advances—particularly in digitalisation, robotics, and remote monitoring—are making well interventions more effective and cost-efficient.
According to SkyQuest Technology, the market was valued at US$9.6bn in 2024 and is expected to reach US$14.73bn by 2032, growing at a compound annual growth rate (CAGR) of 5.5%. Enhanced oil recovery (EOR) techniques and the integration of new technologies will remain key drivers in this expansion.
Regionally, North America dominates the market, led by the United States and Canada, due to a high number of mature fields and strong investment in unconventional oil and gas. Europe is seeing increased activity in the North Sea, while the Middle East and Africa continue to invest in aging infrastructure. Asia-Pacific is emerging as a growth hotspot, with countries like China and India increasing exploration and production efforts.
Several trends are shaping the market. The push into deepwater and offshore fields is generating demand for sophisticated intervention services. Automation and robotics are reducing reliance on manual labour and improving precision. EOR strategies are gaining ground, especially in mature fields. And growing environmental scrutiny is encouraging operators to seek cleaner and more sustainable methods of intervention.
The sector remains highly competitive. Global players like Schlumberger, Halliburton, Weatherford, Baker Hughes, and NOV lead the market, offering advanced services tailored to both complex offshore operations and routine onshore interventions. However, high operational costs, regulatory pressures, and geopolitical risks remain persistent challenges.
Despite these headwinds, the long-term outlook for the well intervention market is positive. As more companies look to extend the life of their assets and operate more sustainably, well intervention services will become an increasingly essential component of global oil and gas strategies.

Nigeria is increasingly looking towards developing its brownfield assets to boost production.
This can be achieved with the right technological interventions, giving way to enhanced oil recovery that can substantially meet the region's refining capacity. Compared to greenfield projects that require considerable investments from scratch, brownfield developments cuts down on carbon footprints, thus allowing operators to meet their sustainability requirements. Ideal technological interventions comprise a package offering e-line, slick line, coiled tubing services, well remediation, well control, and idle well management services. Well intervention operations can range from well conversion, casing run operation on a wild cat well, slot recovery, installation of emergency casing head housing slip, well work-over, and drilling and completion, to name a few.
To facilitate more brownfield developments, the Nigerian administration is working to increase collaboration between the local communities, government and the private sector.
Recently, Nigeria-based offshore construction company called Intrepid Energy Limited joined hands with United Kingdom's Aquaterra Energy to deliver a bespoke subsea well intervention equipment package for a project in Nigeria.
“Working with Aquaterra Energy marks a significant step forward for our intervention operations in Nigeria. Their specialised technology enhances our ability to execute intervention programmes efficiently, maximising performance across our assets. By combining Aquaterra’s technical expertise with our deep understanding of the local operating environment, we’re confident this collaboration will enhance production outcomes and create lasting value for our operations in the region,” said Seun Alonge, CEO at Intrepid Energy Limited.

Global Underwater Hub (GUH) and Subsea Innovation Cluster Australia (SICA) have signed an MoU to collaborate over the development of the subsea sector in both hemispheres.
Under the agreement, the organisations will actively promote opportunities for their subsea supply chains in both countries and share market intelligence and learnings around diversification strategies for the energy transition and defence operation.
GUH Chief Executive, Neil Gordon, said, “Australia has a broad conventional energy mix with strong ambitions towards net zero […] crucially, and similar to the UK, Australia champions a just transition which builds in energy resiliency and security with opportunities in sustained oil and gas production, decommissioning and carbon capture.”
Gordon also highlighted the continued production within the oil and gas industry within Australia where there are opportunities within new developments as well as in the expansion oil current production by leading operators including Woodside and Santos.
He added, “Decommissioning is a significant opportunity in Australia where the inventory of subsea assets requiring to be decommissioned includes over 1,500 wells and structures and 4,500km of pipelines with major opportunities for specialist plugging, cutting, inspection and recovery technologies.”
SICA Cluster Manager, Colin McIvor, commented, “This MoU marks an important step in strengthening collaboration between Australia and the UK’s subsea sectors. By working with GHU, we’re opening new opportunities for innovation, knowledge sharing, and international market access for SICA members. Both organisations bring unique strengths: SICA’s agility and cross-sector innovation focus and GUH’s depth of experience and established global networks. By sharing these, we can deliver real impact for established and emerging industries and accelerate significant growth for both countries.”
A US federal judge struck down a vast lease sale for drilling rights in the Gulf of America, casting doubt over future oil well interventions in the region.
According to various news reports, the judge ruled that Lease Sale 261, held by the Biden Administration, violated environmental regulations, halting activities across more than 283,280 sq km of federal waters.
Organised by the Bureau of Ocean Energy Management (BOEM), the sale had auctioned off approximately 6,475 sq km for US$261.7mn.
The oil and gas lease sale was located in Gulf waters off the coast of Louisiana, and could threaten the survival of the endangered Rice’s whale species, according to environmental groups.
Statistics have placed the number of whales to just below 100 individuals.
Companies such as Chevron, ExxonMobil, and Shell secured leases aimed at boosting production in the Gulf, which supplies 14% of US crude oil, according to the US Energy Information Administration. However, environmental organisations, including Earthjustice and Sierra Club, challenged the sale, claiming it disregarded climate change consequences and risks to the endangered Rice’s whale.
The judge's decision hinged on the National Environmental Policy Act, finding that BOEM failed to properly evaluate the greenhouse gas emissions tied to future oil and gas output. The judge highlighted potential dangers from vessel strikes and noise pollution caused by drilling, deeming BOEM’s environmental analysis inadequate.
The ruling disrupts plans for oil well interventions and new subsea developments. Those projects are now in jeopardy, with the industry awaiting a resolution that could involve a revised review or cancellation of the leases entirely.
Associated Press added that The American Petroleum Institute, or API, an oil and gas trade association representing more than 600 firms and a party to the Gulf Coast case, said it is evaluating its options after this week’s ruling.
Negotiations to determine next steps are underway, but the immediate impact is clear, as billions in investments and planned interventions in the Gulf hang in the balance, leaving operators scrambling to adapt.
As the legal wrangle continues, the ruling underscores the growing tension between energy demands and environmental protection, with the Gulf of America at the centre of the debate.
Petrofac’s Asset Solutions division has secured a series of new contracts and scope expansions in the first quarter of 2025, amounting to US$500mn.

Valued at US$335mn, the deal covers new compression facilities for the Habshan Complex, reinforcing Petrofac’s role in critical infrastructure projects.
Managing Director at Eye-bot Aerial Solutions, David Palmerton, has analysed the current decommissioning ambit within the Gulf of America, the challenges posed by the vast scope of end-of-life work to carry out, and how robotics and data-driven technologies play an integral role in transforming the market.
In the Gulf of America, a significant number of offshore oil and gas wells and platforms are overdue for decommissioning. According to the Bureau of Safety and Environmental Enforcement (BSEE), there are 1,366 offshore structures, with 273 having submitted decommissioning applications and 451 located on terminated leases, of which only 192 have pending decommissioning applications. These delays pose environmental risks, including potential leaks, structural failures, and threats to marine ecosystems as well as increased costs for operators and regulators.
The financial burden of decommissioning these structures is substantial, potentially reaching billions of dollars, with concerns that taxpayers may ultimately bear the cost if companies fail to meet their obligations. A significant portion of these wells are classified as orphaned or abandoned, meaning the companies responsible for their decommissioning no longer exist or lack the financial capability to carry out the required work.
Under regulations set out by the Interior Department, administered by BOEM and BSEE, operators are jointly and severally liable for decommissioning obligations. Even if a company transfers its lease to another operator, it remains responsible for ensuring that all abandonment and removal obligations are fulfilled. Operators must complete decommissioning within one year of lease termination or within three to five years of a structure becoming idle. However, with aging infrastructure and a backlog of overdue removals, BSEE has emphasised the need for proactive compliance throughout the life of a lease.
Given the magnitude of overdue decommissioning in the Gulf, oil and gas operators are turning to advanced technology to enhance pre-decommissioning inspections and streamline project planning. Drones, robotics, and AI-powered digital modelling are now at the forefront of assessing the structural integrity of offshore platforms, pipelines, and subsea infrastructure before decommissioning begins.
By deploying aerial and underwater drones, operators can conduct high-resolution LiDAR scans, ultrasonic inspections, and photogrammetry surveys without sending personnel into hazardous environments. These drone-based inspections provide real-time structural data, detecting corrosion, metal fatigue, and structural integrity risks before dismantling begins.
Simultaneously, AI-driven Building Information Modelling (BIM) and Simultaneous Localised and Mapping (SLAM)-based 3D mapping allow engineers to simulate decommissioning scenarios, optimise removal sequences and enhance worker safety.
The integration of data-driven decommissioning is reshaping offshore well abandonment practices, making projects safer, more efficient, and cost-effective. With thousands of overdue structures requiring removal, these technological advancements offer a critical solution for tackling the Gulf's growing decommissioning backlog.
The process begins with autonomous aerial and underwater drones conducting high-resolution scans of the platform. These drones are equipped with LiDAR, thermal imaging, and photogrammetry sensors, capable of capturing structural details down to the millimetre. The data collected is processed using SLAM technology, generating a real-time digital twin of the platform.
This BIM model provides:
For areas of the platform that are potentially unsafe for human entry, such as confined interiors or corroded sections, a quadruped robotic system is deployed. This autonomous robotic platform is equipped with a LiDAR camera, thermal sensors, and AI-driven navigation, allowing it to traverse hazardous environments, capture high-resolution scans and transmit critical data to the BIM model.
By integrating robotic mobility solutions, teams can inspect structural conditions without exposing personnel to risk, ensuring a complete and accurate dataset for decommissioning planning.
The digital twin model allows engineers to simulate decommissioning scenarios before physical execution, ensuring a safe and efficient process. Potential structural instabilities can be identified, allowing engineers to plan necessary reinforcement measures before deconstruction.
Key considerations for deconstruction planning include:
The decommissioning process is executed with robotic precision, leveraging drones, autonomous robotics and AI-driven modelling.
Some of the execution processes include:
A number of positive results can come from AI-driven decommissioning processes, including a 40% reduction in project time, enhanced worker safety, greater compliance with both regulatory and environmental standards, and increased material recycling and disposal.
As drone technology, AI-driven modelling, and autonomous robotics advance, offshore platform decommissioning is shifting toward zero-contact, data-driven precision. The integration of real-time digital twin modelling, predictive analytics, and autonomous robotic inspections marks the beginning of a fully AI-driven offshore decommissioning era.
