Maria Claudia Borras, Executive Vice President, Oilfield Services & Equipment at Baker Hughes, said, “Baker Hughes has an extensive and successful history of creating value for customers in Norway and the North Sea. The two long-term contract awards from Vår Energi enable us to deploy our superior portfolio not only in well intervention, but also in exploration logging and subsea production.
“Combining our technology, our exceptional regional expertise, and our dedication to a world-class customer experience ensures successful outcomes for both companies.”
Oilenco has secured numerous contracts for the supply of plug and abandonment (P&A) tooling packages to operators and decommissioning specialists across Europe.
The packages include the Oilenco pressure wave valve, an intervention-free, open-on-demand equalising device which is set below a plug to aid in creating a barrier by applying pressure in a series of cycles.
Blair McCombie, Operations Director, Oilenco, said, “Since its first installation in 2018, the pressure wave valve has built an extensive run history and as a result has become one of the leading remote opening devices on the market. It can be functioned when required, within a few hours, days, months or even years after installation without the need for dedicated personnel on location, and once open, provides a large through-bore and pump through capabilities without the need for further intervention.
“Oilenco has a proven track record in the UKCS, providing reliable solutions for P&A campaigns. With these recent contract wins and ongoing requests from clients and decommissioning specialists, our solutions are becoming integral to P&A toolkits.”
WSG has announced it has sold its well intervention division and will use the funds to lay the foundation for a period of international expansion for the rebranded WSG Energy Services (WSGES).
WSGES has diverted its traditional well intervention offerings and will now primarily focus on growing its market share in Process, Pipeline & Industrial Services (PPIS). The business will retain its global footprint with a strong presence in the UK, mainland Europe, Asia and Australia, with its next objective to establish a permanent position in the North American market to capitalise on the success of recent projects.
Proceeds of the well intervention division, which was sold to Excellence Logging (Exlog), a provider of oilfield services, will be used to fund further acquisitions and maintain R&D for refining the company’s emissions management processes and technologies, which are currently in high demand.
Founder Geert Prins will remain an integral part of WSGES’ C-suite as Chairman, while Andrew Burrell continues in the role of CEO.
“Under Geert Prins’ stewardship, WSG’s well intervention division evolved into a successful international well services provider to the energy sector and we are confident that business will thrive under its new ownership,” said Burrel.
“WSGES’ wide range of skills sets and our well established commitment to R&D opens up significant opportunities in energy transition, and we know there is industry-wide interest in our innovative emissions management capabilities, which is an area in which we will continue to invest.”
Chairman Geert Prins continued, “This is part of the natural evolution of the business I set up in 2005, and Phase Two of our success story is in the very capable hands of Andrew Burrell and a highly experienced international management team.”
“Diversification into alternative sectors and developing new products which address emissions management – something the energy sector is committed to – will drive future growth and we have some very exciting developments in the pipeline.”
IOG plc, a UK developer and producer of indigenous offshore gas, has announced that the wireline intervention at Blythe H2 well, located in the southern North Sea, has been completed.
“We have successfully completed the wireline intervention at Blythe H2 well, which has now flowed at a maximum stabilised rate around 42 mmscf/d, slightly above our original 30-40 mmscf/d guidance,” commented Rupert Newall, CEO of IOG. “Production will now be managed up from 20 mmscf/d towards the maximum rate to further dewater the pipeline. The team has worked very well to identify the issue and remediate it safely and efficiently. The significant improvement in our operating team performance is also demonstrated by Blythe operating efficiency increasing from 59% in 2022 to 93% over 1H23 to date.”
The company provided details on the H2 intervention operation which included:
• During well testing prior to H2 First Gas on 12 June, gas flow appeared to be choked back below expected levels by a restriction above the reservoir. Equipment was mobilised to the rig to test whether this was caused by a partially activated downhole valve,
• Over the weekend, the downhole blockage was duly verified at the expected depth. The valve was then fully opened with suitable equipment and the anticipated change in downhole pressure was observed,
• The well was handed back to the operations team in the early hours of Sunday 25 June and subsequently flowed at a maximum stabilised rate of 41.9 mmscf/d,
• Production is now initially set at 20 mmscf/d and will be steadily built up to full rate over the coming week as the Saturn Banks Pipeline System is further dewatered,
• The absence of formation water production from H2 is expected to significantly reduce aqueous liquid arrivals at Bacton, which should in turn reduce unit operating expenditure,
• The plan remains to produce from H2 only over the next few months; once water levels have re-equilibrated at the H1 location, periodic production is planned from H1 at lower rates to minimise water production.
Following the intervention, Newall remarked, “In parallel with the remediation work on H2, we have been assessing next steps for the business very carefully. Mindful of current gas market and balance sheet risks, we have decided to pause drilling activity for now in order to maximise near-term cash flow."
Odfjell Technology, an integrated supplier of offshore drilling, well and engineering services, has achieved an industry-first for cleaning blowout preventers (BOPs) by reaching a 50% time reduction during a successful trial.
Odfjell Technology, over a test period of six months, revised the procedure for cleaning the BOP on the Johan Sverdrup platform in Norway by increasing the pump rate to allow more water flow into the BOP cavities to aid debris removal.
The annular and variable rams were flushed with two passes at the new recommended flow rates to remove debris, then the BOP stack was flushed at the same rate using Odfjell Technology’s RizeRdillo Advanced Jetting Tool. The flow rates went from 1,500 litres per minute (LPM) to 5,500LPM while flushing the annular and from 3,000LPM to 5,500LPM while flushing the BOP.
Results from the successful test period proved that no damage occurred to the BOP and annular with the recommended pump rates, and between six and 12 hours of time could be saved using this new procedure.
The RizeRdillo Advanced Jetting Tool allows for higher pump flow rates, enabling a larger volume of fluid with less pump pressure. This maximises riser cleaning efficiency to reduce operating costs and non-productive time.
Ian Low, Global Product Line Manager, Well Intervention at Odfjell Technology, commented, “By focusing on delivering world class expertise and technology which enables more efficient operations without compromise on safety, Odfjell Technology proves it is the partner of choice for customers time and again.
“Our ethos has been demonstrated by our expert teams achieving this impressive industry-first result for cleaning BOPs. BOPs are essential for safe and efficient well operations, and we are proud to deliver leading solutions to our customers to ensure BOPs are operating at optimal levels.”
Archer has announced the award of a five-year contract for the provision of coiled tubing and pumping services with Perenco UK Limited in the United Kingdom.
The contract, with an estimated value of up to US$50mn, contains two options of one year each and commenced 3 May 2023 in direct continuation of company's previous contract with Perenco.
Dag Skindlo, CEO of Archer, commented, “We are extremely proud to announce this long-term coiled tubing and pumping contract. This commitment reflects our client’s confidence in our ability to maintain safe operations and continue our strong service delivery performance.
“Archer announced the acquisition of the Baker Hughes UK Coiled Tubing business early in 2023 and assumed operations from 4 April. We have successfully transitioned the business and have a dedicated Archer Coiled Tubing team of 50 experienced and skilled employees performing safe and efficient services in the UK.
“We look forward to continuing growing the Archer service offering in the UK and bringing value to our clients’ P&A, workover, and intervention programmes.”
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.”
Subsea intervention technology specialist, Interventek, has agreed to supply a complete set of 20,000psi open-water well intervention shear and seal values to Trendsetter Engineering Inc.
The agreement allows Trendsetter exclusive global rights to deploy the 5-1/8” open-water valves for the next five years, with the first set to be delivered later this year.
The 20K Revolution valves are designed as a compact, modular addition for lightweight subsea intervention systems. They will provide the safety-critical well control function within Trendsetter’s new 20K Trident Subsea Intervention System, which is scheduled for the first field operations on a high pressure, high temperature (HPHT) subsea completion and intervention campaign in the Gulf of Mexico.
Interventek has previously supplied Trendsetter with serval 15,000psi Open-Water Revolution Valves, which were successfully deployed on multiple campaigns using its 15k Trident Intervention Systems.
Tony Kitchener, Sales and Marketing Director at Interventek, said, “Our new 20k Open Water Revolution Valves is leading the way in HPHT subsea well intervention safety. Qualified to rigorous API-17G and API 17TR8 standards, the valve maintains the superior cutting and resilient sealing capability that our unique technology is known for, delivering a future-proof solution for today’s operators.
“Our Revolution design is flexible and scalable so, with Trendsetter’s valuable and long-standing collaboration, it was natural for us to push ahead together to deliver the world’s first open-water HPHT intervention solution.”
Mike Cargol, Vice President of Services at Trendsetter, commented, “Interventek’s compact and high-performing Revolution valve is the ideal choice for our range of lightweight and modular Trident intervention systems. This technology is the key to achieving a reliable HPHT solution with around a 60% size and weight saving compared to other offerings.
“The result is a robust system which can be reconfigured to support hydraulic, riserless or open-water risered interventions and mobilised quickly on a broad range of vessels with minimal modifications. The bottom line for the operator is enhanced safety, rapid responses, increased operational efficiency and reduced costs.”
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.”
