TechnipFMC has been awarded a significant contract by Equinor to provide riserless light well intervention (RLWI) services on the Norwegian Continental Shelf.
The two-year contract (valued between US$75 and US$250mn as per TechnipFMC’s definition of significant) runs from 2024 to 2025, with options to extend for each of the three subsequent years. TechnipFMC will provide production enhancement, production data, and pre-plug-and-abandonment services to Equinor using the RLWI method.
RLWI enables well interventions from a monohull vessel, eliminating the need for a riser and the rig required to connect the riser to the subsea well. Instead, remotely operated Well Control Systems are used to facilitate operations on the seabed. This reduces cost and complexity, increases efficiency, and accelerates the timeframe for increased production.
Jonathan Landes, President, Subsea at TechnipFMC, commented, “TechnipFMC has been providing RLWI services to Equinor since 2006. Over that period, the average duration of an intervention has been reduced by nearly two-thirds thanks to improvements in process and technology, aided by the collaborative relationship with Equinor’s dedicated RLWI team. It is a pleasure to continue developing that relationship as we help our client meet demand for energy.”

Researchers at the University of California, Davis, have suggested the cost of permanently plugging and abandoning the inactive oil and gas wells across the waters near Alabama, Louisiana and Texas could be upwards of US$30bn.
A paper released in the Nature Energy journal stated the area is home to 14,000 inactive wells that have not produced for five years and are unlikely to be reactivated in the region that has become the epicentre of US offshore oil and gas operations.
Leaks from wells closer to shore are more likely to damage ecosystems and release GHG emissions compared to deepwater wells. Studies have found that more than 90% of inactive wells are in shallow waters, and the costs to perform P&A services on those alone would be US$7.6bn.
The findings could help states makes decisions regarding their clean-up priorities, especially as US$4.7bn in federal funding has been authorised by the Infrastructure Investment and Jobs Act.
Liability falls to prior owners to plug and abandon wells in federal waters if the current owners become insolvent and are unable to cover costs. Large US oil companies currently own or have previously owned 88% of the wells in federal Gulf of Mexico waters and would legally shoulder the P&A liabilities.
However, in individual state waters, each jurisdiction handles liability differently, and prior ownership isn’t relevant. States oversee plugging programmes for orphaned wells whose owners have claimed bankruptcy.
“The bulk of the cost comes from plugging wells in deeper water where the environmental consequences are less than for shallow wells closer to shore,” said Mark Agerton, an Assistant Professor at UC Davis and lead author of the paper published.
“That money is probably better spent on state waters where they can’t go after prior owners for clean-up costs and it’s going to be a cheaper clean-up job with more environmental benefit.”

Perenco and Petrodec, a decommissioning services specialist, has announced that the A2D platform topside – located in the Amethyst Field, UKCS – has been safely removed for final dismantling.
The operation was successfully conducted using Petrodec’s patented ‘skidding’ technique deployed by its dedicated jack-up the ‘ERDA’ in the southern North Sea. With a weight of 1,179 tons, this was the heaviest Amethyst topside to have been removed so far.
The news follows the Hydrocarbon Safe (HCS) Campaign on all platforms and brine flushing of intra-field and export pipelines, the plug and abandon of all platform wells, and the removal of C1D, B1D and A2D topsides with a combined total topsides weight of 2,900 tons. The final operations to remove the topsides and four steel jackets of platform A1D are scheduled from January 2024.
The Amethyst field was one of the later-life assets acquired by Perenco from BP in 2012 as part a package of SNS assets. Perenco subsequently consolidated its position to 100% on Amethyst by acquiring the participating interests of Centrica and Murphy Oil in licences P.005, P.030, P.050 and P.133. Amethyst consisted of four conventional fixed jacket wellhead structures with helipads and cranes installed.
The platforms A1D, A2D, B1D and C1D had six or nine slots, and six or seven producing wells. The field stopped producing in 2020, following which Perenco UK started the application for decommissioning operations in collaboration with Petrodec.
Rainier Verhulst, Petrodec’s General Manager, said, “The successful and safe skidding operation to remove the heaviest topside to date exemplifies Petrodec’s technical ingenuity as a decommissioning specialist, bringing together the technical expertise of a contractor and the reliability of a decommissioning operator.
“It also clearly highlights Perenco’s integrated approach to late-life assets, first extending the production lifespan of assets by operational efficiencies and investment, then developing innovative and fit-for-purpose solutions to safely decommission the facilities. I would like to thank all of those involved.”

Brazil has posed itself as one of the key drivers in the Latin American market that is driving the region's growth in the international oil and gas game. A net oil importer until 2014, Brazil has become the top producer in Latin America in 2016, and since then has enjoyed uncontested leadership in the region. While this represents a great opportunity for the region’s oil and gas sector, from the operators to service providers supporting them, there is a looming decommissioning wave on the horizon.
The global oil market has been witness to many ups and downs since the advent of the Covid-19 pandemic. Far from stability, it has weathered a persistent conflict in eastern Europe; re-emergence of Covid-19 in China; major, consecutive price cuts by OPEC+ nations, and a global uptake on renewable activity. The IEA, however, has indicated that oil demand would remain steady until it reaches a peak in the mid-2030’s at 103mn bpd before beginning to plateau. It predicted that despite the global energy mix changing to accommodate the surgence of renewable practices coming to the forefront, fossil fuels will still hold a 60% share within the energy game until at least mid-century.
The Ministry of Mines and Energy (MME) in Brazil has big plans on drawing investment to the country's petroleum sector. It will be focusing on the various ways to drive exploration in frontier areas and call for investments in mature, as well as marginal, economic fields. Owing to these ambitious goals, there is a dual opportunity for both greenfield development and production enhancement through well intervention.
Besides the active role of Petrobras on advancing the country’s oil and gas industry, new players are also emerging as the state-owned Brazilian Petroleum Company has been passing on its mature assets to several entities from BW Energy to Trident over the last few years. Petrobras itself has plans to decommission 26 of its floating platforms, with the P-32 asset scheduled to begin the process this year.
On the other hand, high marketed utilisation rates of offshore rigs, especially in Latin America following the eastern European conflict, led to a supply chain gridlock. While many operators are considering collaboration between companies in order to use the same vessel for their respective assets, logistically, that process could also present challenges.
Another challenge in the well intervention industry lies in tackling the high costs involved in the process. This has resulted in the popularity of a slightly more fresh-faced method – riserless light well intervention (RLWI). Used instead of heavier vessels, this has the potential to significantly reduce cost of operations and minimise environmental impact – an increasingly pressing concern for operators.

Well-Safe Solutions, a contractor which offers the complete package for well decommissioning, has unveiled a D300 saturation diving system aboard the Well-Safe Guardian rig.
The addition, makes the semi-submersible the only one of its type in the North Sea with this capability.
The custom-built dive spread, with capacity for up to 15 persons, enables safe access to legacy subsea wellhead and christmas tree systems from the 1970s onwards which were originally designed for diver intervention.
“With 48% of overall decommissioning expenditure in 2022 focused on well abandonment alone, Well-Safe Solutions has identified a clear market in mature basins such as the UK Continental Shelf for this technology,” commented Phil Milton, Chief Executive Officer at Well-Safe Solutions.
“The dive spread system installed on the Well-Safe Guardian is a cost-effective, flexible alternative to the industry standard, which typically sees a light well intervention vessel (LWIV) used to plug and lubricate the well before completing decommissioning operations with a standard semi-submersible mobile offshore drilling unit (MODU).
“Our ‘single asset solution’ offers an alternative to the conventional approach and does not require multiple vessel mobilisations and demobilisations. This results in lower operating costs, minimises the risk of weather-related disruption and boosts overall project efficiency.”
Milton explained that comparative analysis studies have demonstrated the value this solution can bring to the wider decommissioning industry as it streamlines processes and costs alike.
“Our data shows that the use of the Well-Safe Guardian to plug and abandon (P&A) five wells over three fields in the North Sea generates a 15% total cost reduction and is 44 days quicker than using a LWIV and MODU pairing,” continued Milton. “We are delighted to be able to bring this solution to market as part of our vision to become the industry’s well decommissioning partner of choice.”
The manufacture, transport and fitment of the dive spread was carried out at Burntisland, Rosyth and Methil ports on the east coast of Scotland.
The system is designed to enable diving operations to be carried out in support of well decommissioning. Typical operations supported include cleaning, deconstruction, barrier testing, manual tree cap removal, reconfiguration of hydraulic controls and flowline removal.
Following further systems integration and testing, the Well-Safe Guardian will mobilise early summer 2023, returning to the Buchan field operated by Repsol Sinopec Resources UK to plug and abandon nine wells using the saturation dive system, the Trident well intervention system and the blow out preventer, realising the full potential of this single asset solution. UK-based RockSalt Subsea will support Well-Safe Solutions with diving services and personnel during all saturated diving operations from the Well-Safe Guardian.
David Whitehouse, Chief Executive Officer of Offshore Energies UK, added, “The UK offshore energy industry has a long history of developing world-class solutions to the challenges it has faced and continues to face.
“This latest development and adoption of technology on the Well-Safe Guardian from Well-Safe Solutions shows an absolute commitment to drive forward innovation to improve efficiency for the plug and abandonment of wells. These efficiency improvements will also have a positive impact on safety and environmental performance.
“After 50 years of operating in the North Sea, this level of dedication to UK innovation is important as we continue to meet the UK’s energy needs using home grown jobs, skills and technology.”
