UK-based Odfjell Technology has reported that a workover contract it had in place for south-east Asia has been scrapped by its client, Brunei Shell Petroleum Company Sendirian Berhad.
In a statement, the company said that its client was “terminating this contract for convenience”.
It added: “The client reiterates that the termination is not related to the performance of Odfjell Technology and the two parties remain open to working together on future potential projects.”
Odfjell Technology said that it will close out the contract in accordance with any terms and conditions, with any expenses to be reimbursed by the client.
It also added that there will be “limited” financial effect in 2025 following the cancellation.
Asia Pacific is a region where the company is keen to grow its footprint, however, after entering the Indonesian market, and also landing the services of Australian energy industry equipment provider, R&D Solutions, earlier in the year.
It means Odfjell Technology’s industry-leading well intervention services, wellbore clean up and whipstock tools are now also available to service the Australian well services and deepwater markets, with plans for future growth in the regional plug and abandonment sector.
In its 2024 annual report, released recently, the company also reiterated its global growth ambitions.
“We are well positioned for growth in a competitive market in 2025,” it noted. “Our ambition is to increase our global footprint with well services, entering new geographies as we have in
2024, and focusing on high margin product lines.”
It added that technology development and strategic growth represent a large part of its ambitions for its well services division in 2025.
As well as its European activities, the company is also active in North America, Africa and the Middle East.
But while the cancellation of the project in Brunei may have little immediate impact on finances, it is a blow to the group’s forward aspirations.
In its 2024 annual report, the company noted that the Brunei workover job “opens both an exciting geographical market and type of service, with huge potential.”
Commencement for workover operations in south-east Asia was scheduled for the middle of this year, while mobilisation efforts began last November.
In November, Simen Lieungh, CEO of Odfjell Technology, highlighted the contract’s importance “for significantly increasing our footprint in south-east Asia.”
But in his introductory notes in the 2024 annual report he remained bullish about the group's overall global growth prospects in 2025.
“We will actively explore opportunities for acquisitions and international expansion in line with our strategy,” he noted.
Sentinel Subsea, a specialist in subsea well integrity monitoring, has successfully delivered a six-figure project involving the deployment of two WellSentinel Coral systems for a major operator in the North Sea.
Supporting a large-scale drilling campaign, the project represents a key step in enhancing offshore safety and operational effectiveness.
The Coral systems provided continuous integrity monitoring throughout the well suspension period, helping to ensure safe operations during this critical phase. The deployment took place entirely in February 2025.
Notably, this is the first time the WellSentinel technology has been deployed at the start of a well’s lifecycle, underscoring the value of passive monitoring early in offshore developments. The operator’s adoption of this strategy aligns with the ALARP (As Low As Reasonably Practicable) principle, reducing risk exposure during planning delays before christmas tree installation.
“We are thrilled to have successfully completed this project, which highlights Sentinel Subsea’s commitment to safety, innovation, and growth. This is a key moment for us, as it is the first time our WellSentinel technology has been deployed at the beginning of a well’s lifecycle. Partnering with a major operator in the North Sea strengthens our presence in the region and contributes to our continued global expansion,” said Neil Gordon, CEO of Sentinel Subsea.
The Coral systems were installed onto 18 ¾” wellheads from a jack-up rig via the texas deck using crane wire. As the units were preconfigured for detection before installation, no in-well intervention was required, streamlining operations.
Headquartered in Aberdeen since its founding in 2018, Sentinel Subsea continues to deliver passive monitoring solutions globally for both major and independent operators. This project further establishes its leadership in subsea well integrity monitoring.
The global slickline services market size is expected to reach US$ 8.23bn in 2025, rising to around USD 12.56bn by 2034 at a CAGR of around 2.79%, according to a new report from Custom Market Insights.
According to the report, the offshore segment is dominating the slickline services market as the demand for well intervention in deepwater and ultra-deepwater oilfields, such as Brazil's pre-salt reserves, is increasing.
The report highlights that as oil and gas reservoirs become deeper and more complex, operators are turning to digital slickline solutions for improved efficiency, data acquisition, and automation due to the constraints of traditional mechanical slickline techniques.
Operators are incorporating fibre-optic slicklines, memory tools, and automated control systems that allow for real-time data collection and predictive maintenance. The evolution is transforming the marketplace, enabling oil and gas organisations to remotely monitor well conditions and minimise operational risks.
Digital slickline solutions offer operators immediate access to well data, enhancing well diagnostics as operators can track downhole conditions more rapidly and with improved accuracy, and enabling better and faster decision-making.
The integration of automation and AI is another notable trend driving the slickline services market, the report notes. Automation improves accuracy, reduces human errors, and improves operational efficiency by minimising the need for human involvement.
Predictive analytics use AI to allow operators to predict which equipment will fail and when, allowing them to optimise timing of an intervention, and thereby saving costs. For example, Total Energies and Shell are deploying AI-enabled monitoring systems during offshore operations to ensure the reliability and efficiency of well intervention activities.
As a result, there has been a trend toward robotic slickline units, especially in more remote and dangerous environments where worker safety is a particular concern.
However, such innovations are expensive, proving a constraint to widespread adoption, especially by smaller service providers. This needs to be balanced against the long-term return on investment through improved efficiency, reduced downtime and more accurate well diagnostics.
In the race for innovation in slickline services, industry giants are now investing heavily in next-generation solutions that promise to reshape the slickline landscape, thus strengthening well intervention around the world.
A report by the Australian Academy of Technological Sciences & Engineering on Offshore oil and Gas Decommissioning Technologies has highlighted Australian research and technology capabilities and gaps.
The report argues that there are a number of areas where further R&D would benefit the decommissioning industry, particularly towards the end of the decommissioning value chain around waste management, recycling opportunities and the environmental impact of decommissioning. Australia’s focus on environmental protection will provide opportunities for further research both at home and abroad, the ATSE comments.
With world-leading marine research, strong transferable geotechnical skills from the mineral resources sector, and the government’s Net Zero by 2050 commitment, Australia has an opportunity to leverage this expertise and momentum to drive technology innovations in decommissioning which are suited to Australia’s unique marine ecosystems.
The report highlights Australian strengths in marine science and contamination research, making it well placed to lead research on the impact of contaminants on the environment and ecosystems. The nation is home to three major national marine science organisations – CSIRO, the Australian Institute of Marine Science (AIMS) and the Fisheries Research and Development Corporation, which produce world-leading marine research – as well as a number of other national centres of research excellence in this domain. The report identifies research gaps in contaminant profiling of infrastructure; contaminant exposure limits; mapping of contaminants through ecosystems; long-term impacts of contaminant exposure; real-time, in-field contaminant monitoring technologies; domestic facility re-use profiling; and integrity and environmental management for in situ decommissioning.
Another research strength is recycling; Australia has set ambitious targets for waste recovery and recycling, supported by funding into initiatives such as the AUD $250 million Recycling Modernisation Fund, and the establishment in 2024 of the Solving Plastic Waste Cooperative Research Centre, focused on designing out plastic waste and supporting the transitions of companies in Australia's plastics value chain. The report identifies research gaps in cleaning process optimisation; plastic waste recycling pathways; and new and improved waste recycling pathways.
With well-established oil and gas and mineral extraction industries, and the presence of large industry players driving technological and process innovations, Australia has the opportunity to leverage its expertise to facilitate research into oil and gas decommissioning technologies, the report suggests. Research gaps exist in waste transport approaches; waste management infrastructure and circular economy planning; long-term impacts of contaminant exposure; and domestic facility re-use profiling.
The report notes that Australia and its universities have limited expertise in developing technologies specifically for oil and gas decommissioning, suggesting that Australian universities should be encouraged to develop links with private industry and government research funding to develop the necessary expertise and address capability gaps in conjunction with universities with strengths in these areas, including those in Norway, the UK and the US Gulf of America.
Woodside Energy is currently executing a number of decommissioning projects offshore Australia, and in its Q1 2025 report, outlined progress in the quarter.
The company concluded the multi-year decommissioning programme at Enfield, offshore Australia, safely and successfully completing the removal of all facilities, with the recovery of final infrastructure in February. Only survey activities remain. It commenced deconstruction of the Griffin Riser Turret Mooring at the Australian Marine Complex in preparation for recycling and reuse, and continued decommissioning activities at Bass Strait, completing the plug and abandonment activities for 27 wells, including on the Bream B platform. Plug and abandonment activities commenced on the Kingfish A and Cobia platforms.
Subsequent to the quarter, Woodside concluded the 10-well Stybarrow plug and abandonment campaign, took delivery of a mobile offshore drilling unit at the Minerva field, offshore Victoria, and commenced preparations to plug and abandon the first of three Minerva wells.
Woodside is now planning to undertake subsea and well infrastructure removal decommissioning activities within the Angel Field.
In line with requirements under the Environment regulation, the company has submitted an Environment Plan to National Offshore Petroleum Safety and Environmental Management Authority (NOPSEMA) which is currently under assessment, covering removal of redundant subsea infrastructure in the Angel Field.
The Angel subsea and well infrastructure is located around the Angel production platform in Commonwealth waters, approximately 125 km north of Dampier. The subsea infrastructure is in water depths between approximately 77 m and 85 m. Woodside plans to remove redundant Angel subsea infrastructure and three production wells connected to the Angel platform. Subsea infrastructure removal activities are currently planned to commence by 1 December 2026 subject to approvals and vessel availability. Subsea decommissioning activities are currently scheduled for around three months between around Q3 2026 and Q1 2027.
On its website, Woodside underlines its commitment to executing decommissioning activities with a focus on safety and the environment, coupled with efficiency. “Decommissioning is integrated into project planning and operations, from the early stages of development through to the end of field life. This includes conducting assessments to inform our planning and decision making, which is underpinned by science and marine research. In the developing regulatory environment, we continue to listen, learn and respond to our stakeholders, while expanding our global decommissioning experience,” the company says.
Woodside’s decommissioning approach recognises the importance of reusing and recycling material from its decommissioning activities where possible. Its waste mitigation hierarchy prioritises reduction, reuse, recycling, and treatment over disposal.
Global energy technology company SLB has unveiled Electris, a portfolio of digitally enabled electric well completions technologies designed to enhance production, improve recovery, and lower the total cost of ownership of oil and gas assets.
Electris completions enable digital control over the full productive zone of the wellbore, delivering real-time production intelligence across the reservoir.
This capability allows operators to predict, adapt, and respond confidently to changing production conditions, by optimising reservoir performance throughout the well’s lifecycle and unlocking reserves typically left behind by conventional systems.
“Electris completions take reservoir management to the next level — making it possible for operators to get more out of their assets with fewer requirements for costly well interventions,” said Paul Sims, president, Production Systems. “With much of the ‘easy’ oil already produced, operators are encountering more and more complex reservoirs. Electris completions can help shift the production economics in these reservoirs — resulting in higher recovery factors that maximise return on investment from the asset.”
To date, more than 100 Electris completions technologies have been installed across five countries. In one case offshore Norway, Electris was deployed in an extended-reach well to increase oil production.
The operator is using data from the system to identify which zones are actively contributing to output, allowing them to optimise oil flow and reduce water production.
By managing water output, the system has also cut the energy required to lift and reinject treated water into the reservoir.
SLB launched the new technology last week in Houston, with plans to roll it out for global operations.
Material science and technology provider, 3M, has released via Offshore Network a case study illustrating how an Indonesian oil and gas corporation Pertamina Hulu Mahakam (PHM) deployed Ceramic Sand Screen to cost effectively unlock marginal field assets
While coiled tubing-deployed chemical sand consolidation (SCON) or slickline deployed through tubing metallic screens are the conventional approaches to sand control at PHM, they are limited by its operating envelope and technical constraints. There is a need identified to unlock production with a change in filter media material.
3M Ceramic Sand Screens have saved PHM up to 50% cost over SCON solution and delivered 200% higher productivity than through tubing metallic screen solution by integrating 3M advanced ceramic materials into a sand screen assembly.
Assets like in Tunu and Peciko, reservoirs are marginal and multi-layered sand series which are highly unconsolidated and poorly sorted sands with an average of 20 to 30% porosity. 3M Ceramic Sand Screen have been initially trialed in these conditions and enabled in optimising sand control completions.
Within a span of 4 years, more than 80 wells in various fields of PHM have been successfully replicated.
*How 3M solution has impacted to unlock production from marginal assets
*How material change enables optimised and cost-effective sand control completions
*How 3M material science empowers and contributes to their energy customers to develop improved, safer and more sustainable solutions

With key approvals received and multiple contracts in place, Woodside is advancing towards first oil production from its Trion project offshore Mexico in 2028.
"Since the final investment decision, our teams have tackled challenges head-on, reaching major milestones and entering the fabrication phase," said Stephane Drouaud, Vice President, Trion, while acknowledging the Trion team's dedication and drive in making the project happen.
Three floating production unit (FPU) topside modules are undergoing fabrication work in Ulsan, South Korea. Steel cutting required to prepare the floating storage offloading (FSO) vessel disconnectable turret mooring system (DTM) has been taken care of at the Cosco Shipyard in Qidong, China.
Transocean's Deepwater Thalassa has been hired to spearhead the drilling campaign set for Q1 2026.
Another drilling contract has been reached with SLB to secure the delivery of 18 ultra-deepwater wells over three years. It is also supplying subsea horizontal trees, controls and topside equipment, with manufacturing underway.
Meanwhile, the local teams have made progress on the regulatory front. The environmental permit application has been submitted, and work is underway on the HSE management system permit application.
“We are proud to be a part of Mexico’s energy future,” Stephane said.
“With our ‘one team, one goal’ mindset, I am confident we will continue making history as we deliver Mexico’s first ultra-deepwater development.”
The Trion field lies 180 km off the Mexican coast at a water depth of 2500 m and was discovered by Mexican National Oil Company PEMEX in 2012.

In yet another move to roll back Biden-era legislation, The U.S. Department of the Interior (DOI) has announced it intends to revise the Bureau of Ocean Energy Management’s 2024 Risk Management and Financial Assurance for OCS Lease and Grant Obligations Rule.
The rule increased the financial assurance requirements for offshore operators to ensure they meet their decommissioning obligations and was designed to “better protect the taxpayer from potentially bearing the cost of facility decommissioning and other financial risks associated with OCS development, such as environmental remediation.”
This rule was challenged by the Republican-led states of Louisiana, Mississippi and Texas and oil and gas industry groups, who argued that it would result in "potentially existential consequences" for small and medium-sized companies, although a federal judge earlier this year rejected their bid to block the rule. According to the DOI this rule was estimated to increase financial assurance requirements for offshore oil and gas operators by US$6.9bn in additional bonding, costing businesses an additional US$665mn in premiums each year.
The Trump administration intends to develop a new rule that will supposedly cut costs and red tape and free up billions of dollars for American producers to use to explore and produce oil and gas in the Gulf of America while protecting American taxpayers against high-risk decommissioning liabilities, according to the DOI statement.
“This revision will enable our nation’s energy producers to redirect their capital toward future leasing, exploration, and production all while financially protecting the American taxpayer,” said DOI Secretary Doug Burgum. “Cutting red tape will level the playing field and allow American companies to make investments that strengthen domestic energy security and benefit the Gulf of America states and their communities.”
The Department expects to finalise the rule this year, and will welcome public comments on the proposal.
The Bureau of Ocean Energy Management will continue to require all operators on the Outer Continental Shelf to provide financial assurance for their decommissioning obligations.
The Norwegian Ministry of Energy has unveiled its 2025 licensing round on the Norwegian Continental Shelf, dubbed APA 2025, marking the largest area ever offered in a single licensing round.
Announced last week, the move aims to bolster exploration and production in one of Europe’s key petroleum regions, with applications due by 2 September, 2025, and new production licenses set to be awarded in January 2026.
The annual Awards in Predefined Areas (APA) rounds grant oil companies access to mature and well-explored petroleum zones on the continental shelf.
This year’s offering covers approximately 75% of the shelf’s total area opened for petroleum activities, including a significant expansion of 76 blocks: eight in the Norwegian Sea and 68 in the Barents Sea.
“We need to explore more, discover more, and produce more. That’s why it is important to ensure companies have stable access to exploration acreage. Never before has a larger area been announced in a licensing round. This is good for Norway and for Europe,” said Minister of Energy Terje Aasland.
The APA 2025 round follows a public consultation process and builds on technical petroleum assessments, prioritising continued exploration to counter an anticipated production decline after 2030.
Aasland emphasised the strategic importance of the Barents Sea, where the bulk of the new blocks are located, noting that the expansion “provides companies with access to significant new acreage in the Barents Sea, helping us further clarify the resource potential in the north.”
After over five decades of exploration, the APA framework now encompasses most of the shelf’s accessible acreage, making these rounds a linchpin of Norway’s petroleum policy.
“The APA rounds are a cornerstone of the government’s petroleum policy. Continued exploration and new discoveries are essential to limit the decline in production on the continental shelf after 2030,” Aasland stated.
The minister also called on the industry to seize the opportunity, urging companies to “take responsibility by identifying and applying for opportunities with significant resource potential — in addition to continuing near-infrastructure exploration.”
This push comes as Norway seeks to map its resource base before ageing infrastructure is decommissioned.
Companies have until 12:00 CEST on September 2, 2025, to submit applications.
Detailed information, including updated block maps, health, safety, environmental, and fisheries considerations, is available on the Norwegian Offshore Directorate’s website.
The APA 2025 announcement underscores Norway’s commitment to sustaining its role as a major energy supplier while navigating the challenges of a maturing continental shelf. As Aasland put it, the stakes are high “for Norway and for Europe.”
Valeura Energy Inc has taken a decision on investing in the redevelopment of the Wassana field in the offshore Gulf of Thailand
The investment is expected to create a significant value for shareholders. Currently, the production from the field is carried out through a MOPU facility whose life is expected to finish at the end of 2027. The facility is also limited in the number of future development wells that could be drilled and has insufficient oil and fluid processing capacity to recover the expected reserves and resources of oil in the G10/48 licence.
The Company has reviewed a number of different redevelopment concepts for the Wassana field and has selected a new central processing platform (CPP) with 24 production well slots as the optimal development concept to yield both the highest financial returns and the maximum total recoverable oil from the G10/48 licence. The new CPP will replace the existing MOPU production infrastructure and is expected to allow for a more holistic commercialisation of the field’s oil reserves, both by enabling more aerially extensive drilling reach and also by way of a longer facility design life, resulting in more years of cash flow generation.
The Company has selected Thai Nippon Steel Engineering & Construction Corporation Ltd, recognised for being a very capable Engineering, Procurement, Construction, and Commissioning (EPCC) contractor with four decades of experience in developing similar type of facilities in Thailand. Following the completion of the initial development wells, the Wessana field is expected to produce oil at rates of 10,000 bbls/d in the second half of 2027.
The company expects to spend US$40mn on the Wassana redevelopment project, with their guidance for Adjusted Capex being revised to US$165mn to US$185mn for the full year 2025, with free cash flow guidance also being provided.
In a contract with Shell Offshore, innovative solutions provider, CRP Subsea, will be supplying crushable foam wrap (CFW) for the Whale deepwater development situated 200 miles south of Houston in the Gulf of America
The contract covers one well-set to be delivered by Q3 2025, followed further by the generation of four additional well-sets over the year. Each well-set are made of 1,798 CFW quadrants, each one metre in length. Other components include installation equipment, such as adhesive (one tube per two quadrants), adhesive dispensing guns, tie wraps, and Spanset straps.
An engineered syntactic foam, CFW comprises of a thermoset resin and hollow glass microspheres (HGMS). Once installed around the inner drill casing, it is immersed in the annulus fluid. As pressure within the annulus increases, the CFW will collapse at a pre-determined pressure and temperature combination, as dictated by well conditions. This controlled collapse allows for the expansion of annulus fluid, dispersing potentially destructive pressure build-up.
Andy Smith, Head of Sales, said, "It’s fantastic that Shell has chosen us to support this exciting deepwater project. We’ve been manufacturing and deploying crushable foam wrap for decades, helping to protect wells around the world. This contract is a great validation of our team’s expertise and dedication to delivering high-quality solutions for the industry."
The CFW will be produced at the company's Skelmersdale facility, once project engineering begins shortly.
