Serica Energy, a British independent oil and gas exploration and production company with a portfolio of exploration, development and production assets, has indicated its intention to pursue a well intervention campaign in the years to come.
In its recently published Corporate Update presentation for the year ended 31 December 2021, the company made the announcement alongside its intention to continue with its programme of through-cycle investment in its diversified portfolio of assets; drilling for the North Eigg exploration well in the summer of 2022; and its plans to grow cash balances to offer increasing options for futher investment, acquisition and distributions.
In the statement, the company wrote, “Plans are also in place for a well intervention campaign to take place in 2022 to improve the production potential of several Bruce and Keith wells during subsequent years.”
Bruce and Keith are two assets off the coast of the Orkney Islands. Together with Rhum, they provide a significant contribution to the UK gas demands and are estimated to contain net 2P reserves of 50.9 mmboe as of 01.01.21, of which more than 80% is gas.
ReLineWL, the expandable technology designed to unlock greater commercial value by maximising production from existing wells, has been successfully deployed in the Middle East for the first time by developers Coretrax.
The global well integrity and production optimisation leader’s ReLineWL is a one-trip, wireline deployed straddle system to address common well integrity issues.
It is proven to deliver a 700% greater flow area when compared to traditional straddles, securing safety and sustainability benefits by reducing the number of onsite personnel required to complete the work.
Introduced in the Middle East for the first time, ReLineWL was deployed to support a major Saudi operator when water ingress on a producing well led to decreased oil recovery. Two ReLineWL 28ft straddles were deployed on e-line, enabling the operator to isolate several perforation intervals to shut off water production zones.
Compared to traditional tools, the ReLineWL’s outer diameter (OD) allowed the system to pass through restrictions before they were expanded and set at almost 7,000ft. The tool delivered a large post-expansion inner diameter, providing maximum production conduit to surface over conventional options.
The well was successfully brought back online with a 31% reduction in water production and additional oil production of 1,400bbls/day. With the requirement for surface water management also reduced the application also significantly reduced the operator’s carbon footprint.
John Fraser, Chief Executive Officer of Coretrax, commented, “The Middle East is a key growth area for Coretrax and the first deployment of our ReLineWL in the region is a significant milestone for the business as we continue to enhance our technology portfolio to support the most complex well integrity challenges. As operators remain focused on maximising recovery efficiently and sustainably, our expandable technology is ideally placed to support this demand.”
Available in various CRA materials, the tool can be configured to smart completion products such as autonomous inflow devices (AICDs) to enhance production by selectively eliminating gas and water production and provide a comprehensive workover solution.
The RelineWL has a high expansion ratio of 75% and is designed for stackability creating a longer, integrated straddle to be deployed, without losing ID. This also allows operators to gain access below if well intervention is required at a later date.
“The ReLineWL already has a proven track record in North America and I’m excited to see this successfully deployed in the Middle East for the first time. As we head into 2022, we already have a healthy pipeline of projects in the region and look forward to working closely with our customers to transform current well performance and deliver greater operational efficiencies,” Fraser continued.
Petrogas E&P Netherlands B.V. (a part of Petrogas E&P LLC) has awarded Heerema an integrated engineering, preparation, removal, and disposal (EPRD) decommissioning contract for multiple North Sea oil platforms.
The work involves removing the Haven, Hoorn, Helm, and Helder platforms from Block Q1 of the Dutch sector in the southern North Sea.

This contract demonstrates Petrogas’ commitment to the safe and timely removal of our facilities and we are very pleased to have signed this contract with Heerema, whom we believe is the ideal partner for this project with their commitment to sustainability and circularity.”
The platforms have been important contributors to the Dutch oil and gas industry over the last 40 years, with the Helm platform being the first to produce oil on the Dutch continental shelf for the Dutch market. Their removal, which will take place over several years, is the final stage in a key part of the Netherlands' energy history.
Koos-Jan van Brouwershaven, Heerema's CEO, commented, “Heerema is proud to be Petrogas E&P Netherlands' chosen contractor for this significant decommissioning project. Our team is looking forward to working closely with Petrogas to prepare and execute the safe and sustainable decommissioning of these platforms. Heerema has installed the majority of North Sea platforms, and we believe in the circularity of removing these structures, leaving the sea as we found it. This action aligns with our own sustainable and circular ambitions to reuse and recycle wherever possible.”
TotalEnergies E&P Danmark has awarded Maersk Drilling a contract for well intervention services in the Danish North Sea.
Maersk will employ the high-efficiency jack-up rig Maersk Reacher to carry out the 21-month contract which is expected to commence in July 2022. The contract includes options to extend the duration by up to 27 additional months.
Maersk Reacher is a 350 ft, Gusto-engineered MSC CJ50 high-efficiency jack-up rig which was delivered in 2009. It is currently operating offshore Norway where it is scheduled to be replaced in a rig swap with Maersk Integrator end-February/early March 2022. Maersk Reacher will undergo a special periodic survey prior to commencing the contract with TotalEnergies.
Claus Bachmann, Head of North Sea Division in Maersk Drilling, commented, “We’re happy to build further on our long-standing collaboration with TotalEnergies by adding this long-term contract which means that two of our rigs will be working for TotalEnergies in Danish waters this year. Maersk Reacher will be available for the job after being released from its current work scope in Norway through the planned rig swap with Maersk Integrator.”
DNO has awarded a decommissioning contract to Heerema Marine Contractors for the integrated engineering, preparation, removal, and disposal (EPRD) of the Ketch and Schooner platforms.
The Ketch and Schooner platforms are located in the southern North Sea in the UK sector and were installed by Heerema in the 1990s. Both platforms are tied-back to the Murdoch complex, which will also be removed by Heerema Marine Contractors.
The Ketch platform is located in a water depth of 54 metres, and the Schooner platform is located at 71 metres of water depth. After removal, both structures will be responsibly disposed of and will be reused or recycled up to 97%.
Michel Hendriks, Heerema’s Decommissioning Director, commented, “Heerema is proud to be the contractor of choice for the decommissioning of the Ketch and Schooner platforms. The EPRD award is the result of our ambition to remove offshore structures of all sizes in a safe and sustainable manner.
“We are especially pleased to contribute to the circularity of the project by being the installation and removal contractor, which is in line with our own sustainable circular ambitions.”
Using Wire Arc Additive Manufacturing (WAAM), Vallourec has recently produced two lifting plugs for Weatherford with meet its urgent operational demands.
When Weatherford approached Vallourec with an urgent request for a VAM TTR HW Riser Lifting Plug capable of 100T for a customer’s workover scope off the coast of Australia, Vallourec proposed a more economical and faster solution using Additive Manufacturing (AM) in order to meet the deadline.
The lifting plugs were re-designed with WAAM to include tailor-made non-standard diameters that were compatible with Weatherford’s existing equipment. The lifting plugs’ outside diameter (OD) was therefore increased by 15% as per the customer’s request. Leveraging WAAM’s flexibility, Vallourec was able to mitigate any weight increase by re-designing the component without impacting lifting performances.
The 3D-printed safety-critical components weighed 175kg each with a tailor-made diameter of 50cm and were designed for load carrying applications of around 100 metric tons.
These new lifting plugs were 3D-printed with the Vallourec WAAM robot located in Singapore, only a six-hour flight away from the end-customer. The safety-critical components were delivered in just under two months instead of the usual three to four months.
“We approached Vallourec with an urgent request for a lifting plug for a customer of ours operating in the Timor Sea. Their solution was to use WAAM, a more economical and quicker option to the traditional route”, explained Shane Ferguson, Project Manager for Weatherford. “They executed this on time and delivery was made well before operations commenced. We were extremely happy with the finished product and will look to Vallourec and this method for future requirements.”
WAAM – and AM more widely – offers numerous benefits for the oil and gas industry, one of the most important being shorter, guaranteed lead times, which would make a huge difference to end users. WAAM also allows for greater freedom of shape – parts can be created to the exact size and specifications of each customer – as well as for printing of very large components. The ultimate benefit of this process is to allow companies to create a digital or virtual warehouse through which they can order spare parts as a printable file.
Thanks to WAAM, Vallourec is able to eliminate the traditional concerns regarding the unpredictability of material sourcing and minimum order quantity requirements, providing customers with solutions meeting their specific requirements any time.
“We look forward to making possible future projects such as this one, providing customers with the high quality they are used to from Vallourec with faster delivery times”, commented Jinwei Li, Asia Pacific Sales Manager at Vallourec.
