Neptune Energy has announced an agreement to create new ‘digital twins’ of two offshore platforms in the Dutch North Sea, expanding its portfolio of digitised assets to 14 in total.
The twins will enable engineers to carry out traditional offshore work from an onshore location, accelerating work schedules and reducing costs. UK-based 3D technology specialist, Eserv, will digitise the Neptune-operated D15-A and K12-C platforms, after previously creating digital versions of 12 platforms in the Dutch and UK sectors.
This technology allows Neptune teams to virtually visit assets, leading to thousands of hours of work being completed from office-based locations since the twins were introduced.
Neptune Energy’s Director of Operations for the Netherlands, Stephane Lacote, said, “The use of 3D technologies such as digital twins have provided significant benefits including reducing operational costs by enabling traditional offshore activities to be completed quickly and efficiently, without travelling offshore.
“Our engineering teams can now virtually visit platforms to support the safe running of operations from anywhere on the planet.”
Digitising operational assets to improve safety and productivity, as well as reduce environmental impacts, supports Neptune’s aims to enhance asset integrity and provide employees with technologies that support collaboration with colleagues globally.

The team of AIS Survivex, an offshore training provider in the UK, has received an insight into life on board a decommissioning rig courtesy of Well-Safe Solutions.
Members of AIS Survivex were invited on board the Well-Safe Defender to let them experience life on a bespoke well plug and abandonment semi-submersible rig which accommodates 110 energy workers. It was described as an enlightening experience which allowed the team to understand more about the working conditions and challenges for the people they help train. AIS Survivex has been delivering and managing all training for Well-Safe since 2019 and is currently carrying out a range of training to prepare the Well-Safe Defender’s crew for its forthcoming campaigns.
The rig itself used to be used for drilling operations in the North Sea but, since being taken into Well-Safe’s ownership in 2022, has been converted to play a part in the energy transition as a bespoke well decommissioning asset. Currently, the rig is undergoing a host of efficiency enhancements ahead of its mobilisation this month for a well P&A campaign with Spirit Energy on the Trees and Chestnut fields.
laire Adams, Training and Competency Advisor at Well-Safe Solutions, commented, “With over 360 staff working for Well-Safe Solutions, we are focused on safe, smart and efficient delivery of well plug and abandonment – and all of this begins with effective training. AIS Survivex have supported Well-Safe Solutions on multiple occasions by providing multi-skilled trainers to provide rig-based training on all our assets as part of our rig readiness plans.
“Two AIS Survivex multi-skilled trainers were delivering a suite of courses to our crew onboard the rig to enhance personnel and team compliance against our matrix. The input of the AIS Survivex trainers is paramount in ensuring the relevant Well-Safe Solutions personnel held the correct training certification to ensure operational compliance prior to the rig mobilising for its upcoming P&A campaign with Spirit Energy. Collaborative working is key to our success and a safety-first mentality is critical for offshore workers.”
BiSN, a supplier of downhole sealing solutions and technology, has caught up with representatives from Aker BP regarding the successful plug and abandonment campaign conducted in the Valhall oilfield in 2020.
Aker BP needed to safely P&A 30 wells in the Valhall field in the North Sea and partnered with BiSN to deploy Wel-lok technology to create safe and cost-efficient Wel-lok plugs. After extensive testing conducted over the past two years, it has been shown that not only did this provide a permanent plug and abandonment solution, it allowed for new wells to be drilled and operated safely for the next 30 years.
“As part of the success story, we are monitoring the same wells today and we’re proud to say that out of the 30 wells today there is no leakage,” said Kjetil Vadset, Senior Drilling Engineer, Aker BP.
For two years prior to commencing the campaign in 2020, Aker BP and BiSN carried out a joint testing programme at BiSN’s Houston location to ensure Wel-lok technology was the safest, most cost-effective option. As a result of completing this rigorous testing programme, BiSN Wel-lok technology received acknowledgement of consent for use, including DNV-GL verification and PSA (NORSOK) evaluation of bismuth.
“Qualifying Wel-lok technology for use in the North Sea and securing a long term partnership with Aker BP were two major priorities for BiSN at the time,” said Paul Carragher, Founder and CEO of BiSN. “We are looking forward to continuing to develop a one team relationship with Aker BP on their forthcoming P&A campaigns.”
By implementing Wel-lok technology over traditional cement, it is estimated that the campaign saved approximately three months of rig time, or approximately US$2mn per well.
As part of the campaign, BiSN delivered the largest bismuth plug ever deployed to date. Produced at BiSN’s UK facility, the tool weighed in at 33,191 lbs and sealed up to 30 inches in the wellbore.
“We're very proud. The operation has gone beyond expectations. We planned and hoped for 72 hours per installation. We're down to 33 hours per installation just now,” said Vadset.
For the consideration of the secretary of state for energy security and net zero, Dana Petroleum (E&P) Limited has submitted a draft decommissioning programme for the Western Isles floating production storage and offloading (FPSO) vessel and its associated mooring systems, risers and dynamic umbilicals.
The associated infrastructure of the FPSO are located within UK block 210/24a in the northern North Sea which lies approximately 90 km to the northeast of Shetland and 58 km from the UK/Norward median line.
The draft decommissioning programme covers one vessel and associated subsea infrastructure including 12 mooring lines (three groups of four lines), nine flexible risers and two dynamic umbilicals.
Well-Safe Solutions, an international well decommissioning specialist, is supporting the decommissioning of two suspended wells in bp’s Kate field in the North Sea, 220 km from Aberdeen.
The programme of work, expected to be executed from the Noble Innovator jack up vessel during Q2 2023, will see Well-Safe Solutions carry out well engineering support services using its bespoke well decommissioning delivery process (WDDP).

“Well-Safe Solutions will be instrumental in establishing and evaluating key subsurface isolation criteria including identifying and quantifying zones of flow potential and risks associated with redevelopment. In addition, we will also examine existing barriers and optimise the barrier strategy, taking into account the attributes of the region to safely and efficiently deliver this project.”
James Richards, Well Abandonment Director at Well-Safe Solutions, added, “The well decommissioning delivery process guides operators through the well plug and abandonment process efficiently and effectively, without the extended commitments and high costs historically associated with engineering resources over long periods.”
Decommissioning and P&A specialist, Mermaid Subsea Services UK, has been awarded a multi-well contract on behalf of North Sea operator following the completion of its inaugural vessel-based P&A campaign.
The two-year contract includes the decommissioning of 22 wells, representing the integrated subsea provider’s largest contract to date, and the creation of 12 new roles at Mermaid’s Aberdeen headquarters.
Scott Cormack, Mermaid Regional Director, commented, “We are delighted to announce the award of this contract, which follow hot on the heels of our well P&A activity during Q4 2022 with collaborative partner, Exceed.
“This project serves to underline the reputation we have so quickly gained for safe, efficient and cost-effective vessel-based well P^&A, which draws upon or core team’s combined track record across the decommissioning sector.”
According to the company, activity relating to the newly acquired contract is already underway.
Vår Energi ASA is set to plug and abandon a well in production licence PL229, northwest of Hammerfest, following the discovery of oil in the operated 7122/8-1S Countach well.
The well was drilled in one of the segments that form the Countach prospect and preliminary estimates place the size of the discovery in the tested segment between 3-13mn bbls of total recoverable oil equivalents. The potential of the Countach prospect, in the undrilled segments, is estimated at up to 23mn bbls of total recoverable oil equivalents.
Following the discovery, the well will now be permanently plugged and abandoned, and the licensees will evaluate drilling an appraisal well in the future.
Rune Oldervoll, EVP Exploration and Production in Vår Energi, said, “Countach reinforces the company’s position as the leading exploration company on the Norwegian shelf. This discovery is yet another in a series of successful exploration wells in the Barents Sea in recent years, including Lupa – the largest discovery on the Norwegian shelf in 2022.
“At the same time, the discovery confirms our exploration strategy and our position in the area. We will consider potential commercial development options and tie-in of the discovery to Goliat FPSO. Due to late arrival of the drilling rig on the field this winter, we have not been able to carry out the planned sidetrack before the environmental drilling restrictions commence on 1 March. We look forward to continuing to explore the area around Goliat at a later point in time.”
The well was drilled to a measured depth of 2,989 metres and oil was encountered in the Realgrunnen and Kobbe formations. With extensive data now collected for further assessment, the well will be permanently plugged and abandoned.

Sval, Storegga and Neptune have formed a partnership to apply for a CO2 storage licence in the Norwegian North Sea for the Trudvang project.
The Trudvang licence, located to the East of the Sleipner field, has the potential to store up to 225mn tonnes of CO2 and comes after the Norwegian Ministry of Petroleum and Energy announced a new area in the North Sea for applications related to injection and storage of CO2.
Truls Olsen-Skåre, Senior Vice President Sustainability & HSEQ in Sval Energi, commented, “Carbon capture and storage (CCS) is a solution that can significantly reduce CO2 emissions. The partners have worked jointly since December 2021 to identify, nominate, and apply for this licence. We have undertaken a substantial amount of work already, including subsurface evaluation of the storage complex, and technical and economic assessment of the CCS value chain. This work has shown that Trudvang can be matured into a commercially viable project with safe and efficient carbon storage.
“We will focus on accelerating all phases of the work programme to be able to start injecting CO2 in 2029, and we will continue our work with existing and new parties to mature the full value chain.”
The Trudvang project envisages the capture of CO2 by multiple industrial emitters in Northern Europe and the UK, the shipping of liquid CO2 from export terminals to an onshore receiving terminal in the south-west of Norway and then transport via a purpose-built pipeline to the Trudvang location for injection and permanent storage.
Nick Cooper, CEO of Storegga, remarked, “CCS is essential, as one of the few technological solutions that can prevent CO2 emitted from industrial operations from entering the atmosphere and worsening climate change. Our Trudvang announcement today builds on Norway’s pioneering progress with the world’s first industrial-scale, multi-user CCS project. We look forward to continuing our work with Sval and Neptune to ensure that the Trudvang Project will have a significant impact on carbon emissions and a positive impact on the Norwegian economy.”
Optime Subsea has signed a long-term framework agreement with Wintershall Dea for use of the company’s remote controlled subsea well completion and intervention systems.
Under the agreement, Wintershall Dea will rent three Remoted Operated Controls System (ROCS) including its universal landing string system (panpipe), and two wireless electric subsea control and intervention systems (eSCILS) from Optime Subsea. The latter will also provide technical service personnel to support Wintershall Dea’s operations.
Jan-Fredrik Carlsen, CEO of Optime Subsea, commented, “This contract manifests our position as the leading global supplier of remote-controlled well completion and intervention systems. Our solutions are tailored to simplify subsea, entailing less equipment offshore, lower weight, less logistics, lower HSE risk, lower emissions and lower costs. We look forward to supporting Wintershall Dea in achieving this.”
The ROCS is a fully battery-powered and umbilical-less system for well completion operations, eliminating the need for the costly and heavy umbilical’s which normally run from topside to seabed, as well as the need for a hydraulic unit. In total, this avoids the mobilisation of approximately 50 tonnes of topside equipment. The eSCILS is also a battery-powered and umbilical-less device, used for subsea well interventions and workover operations. eSCILS is lowered to the seabed next to the well and can connected to any type of subsea tree, requiring only a computer for a topside control system, rather than additional rig equipment, and can be mobilised and demobilised in one day. As a result, operations can be done significantly safer, faster and more cost-effective than conventional solutions.
The agreement is valid for a firm period of three years plus two additional two-year options. If both option periods are exercised, Optime Subsea estimated that the contract could generate total revenues of around NOK500mn.
