UK-based, closed-loop geothermal energy developer, CeraPhi Energy, has acquired the business of Third Energy Limited, a former shale gas development company with plans to repurpose the existing wells into clean geothermal energy centres.

The acquisition includes the subsidiaries, namely Third Energy Trading Limited, Wolfland Renewables Limited, Wolfland Utilities Limited, Third Energy UK Gas Limited, and the 50% holding in West Heslerton Renewables Limited.

The assets located in North Yorkshire, UK, include eight well sites consisting of 12 former gas wells in a suspended state, 22.4 km of 6-inch and 16.6 km of 3-inch subterranean pipelines and a further 22.4 km of buried fibre optic comms lines. 

CeraPhi completed a commercial demonstration of its CeraPhiWell system earlier in the summer using the Third Energy KMA site. CeraPhi’s strategy is to de-risk the scaling and commercialisation of large-scale heat networks using boreholes down to a depth of 2km, reducing the space required for deployment of large-scale systems and increasing the extraction of thermal energy available for network connections. By both drilling new wells and repurposing end-of-life and non-producing oil and gas wells, the CeraPhi solution will provide 'huge commercial potential' for the scaling of geothermal heat networks in the UK and globally.

CeraPhi Energy CEO Karl Farrow said, “The decarbonisation of heat represents a huge UK and global challenge in meeting our net zero targets. Combined with the continued insecurity customers face with volatility and seasonal cost of fossil fuels, we have to move geothermal energy to scale to reduce the cost of deploying direct use heat, which is an endless resource not subject to price fluctuation, enabling a move away from our dependency on fossil fuels within our day to day energy mix.

"By using the inexhaustible resource beneath our feet using closed-loop technology we can access this energy anywhere with zero environmental risk, requiring no hydraulic fracturing, no use of water and providing enough energy within the next 15 years to solve our energy crisis indefinitely."

Third Energy Managing Director Russell Hoare said, “At Third Energy we’ve been pursuing a transition strategy for several years now with geothermal energy at the centre of that strategy and in CeraPhi we have found a capable and accomplished partner, as proven by the successful geothermal demonstrator project at our KMA site this summer. Bringing together the expertise of CeraPhi with the assets of Third Energy is a natural progression and I look forward to working with Karl and his team to continue the story.”

As part of a North Sea project this year, subsea engineering company Interventek will be supplying a newly developed, compact and lightweight bore selector technology to decommissioning services provider, Well-Safe Solutions.

Interventek will also provide life of tool support including training, services and critical spares.

Interventek’s CEO, Alan Duncan, explained, “This type of compact and lightweight technology is currently limited in market availability, so the provision of our new solution to tier one service companies will help to enhance industry efficiency and cost-competitiveness, particularly in the decommissioning sector. We’re delighted to have been selected by Well-Safe as a new equipment supplier and are dedicated to supporting them in delivering optimum results to operators.”

Steven Chalmers, Wells Subsea Manager at Well-Safe Solutions, said, “Well-Safe Solutions is committed to realising safe, smart and efficient well decommissioning operations. New technology plays a vital role in making operations as efficient as possible and Interventek’s Bore Selector will help to boost efficiency when deployed from the Well-Safe Guardian.”

Increased operational efficiency

The design of the bore selector supports the industry’s move towards more compact and lighter weight systems with improved deck handling and deployment efficiency. The tool’s function allows a monobore riser or riserless system to be used for intervention on a dual bore Xmas tree. This means that dual bore interventions can be carried out without returning the system to surface to realign the riser for annulus bore access, enabling access to a large number of wells in a shorter period of time, with increased operational efficiency. It is positioned between the tree running tool and the lower riser package and uses an actuated flapper which can be moved manually via a standard ROV interface or hydraulic surface controls. The flapper position directs the wireline toolstring into either the production bore or the annulus. A bi-directional ball valve is also integrated into the annulus access route to enable circulation of fluids during operations.

The AGSM AIM Group has invested in a specialised geothermal energy project in Verona, Italy, which will see the construction of geothermal wells capable of providing clean thermal energy to those connected to the district heating network.

The project process, which began in December 2023 with the approval by the Board of Directors of AGSM AIM as part of the industrial and economic plan of the ‘Geothermal Project’, will continue over the coming weeks with the establishment of a company to lead the project.

The project will provide geothermal energy to five cogeneration plants in Verona located in Borgo Trento, Forte Procolo, Golosine, City Center and Banks, as well as the Vicenza district heating plants in the future. Utilising geothermal energy is a key part of the objectives and actions envisaged by AGSM AIM’s industrial and strategic plan which places sustainability among the main pillars of growth for the group.

Federico Testa, President of AGSM AIM, said, “Thanks to this important technology our Group confirms that it faces the challenges of the energy sector with a new vocation of values, always directed towards sustainable development and cost containment for citizens and businesses.”

The project aims to bring economic benefits to district heating customers due to the strong reduction of methane gas that will be compensated by geothermal resources. The thermal source is expected to save more than 40% of the gas consumed by the region, thus reducing CO2 emissions by approximately 30,000 tons.

A UK£1mn investment in developing its largest subsea Chopsaw to date has paid off for Decom Engineering (Decom) following impressive results on its first deployment.

The C1-46 Chopsaw played a pivotal role in a subsea infrastructure decommissioning project on behalf of DeepOcean in the northern region of the North Sea.

This ambitious project involved the removal of pipelines, control umbilicals, and various subsea structures from the seabed in water depths of up to 180 metres, each requiring precise and efficient cutting.

The Decom team was tasked with cutting a wide range of pipe sizes, from 1,042 mm OD concrete-coated carbon steel pipes to 220 mm OD super duplex pipes. These subsea pipelines needed to be segmented into 9.5 metre sections for efficient recovery to the vessel deck.

Powered from topside and ROV using a Hydraulic Power Unit (HPU), reeler, hot stabs and control panel, the C1-46 exceeded all expectations, proving its worth in the harshest of subsea environments. The smaller C1-24 chopsaw was utilised for certain tasks and also operated with a mix of topside and ROV controls.

The C1-46 averaged 15 cuts before requiring a blade change, significantly reducing the need for recovery to the surface and impressively completed 79 cuts on its first deployment, showcasing a remarkable 100% success rate.

Substantial time savings of almost 300% were achieved compared to using traditional diamond wire saws which typically have longer cut times, carry a risk of wires breaking, and require multiple trips to the surface vessel for blade replacement. Using customised insertable and replaceable tips voided the need for blade changes, reducing costs and increasing efficiency by minimising vessel time.

In contrast, the C1-46 completed some cuts in as little as 20 minutes, while the C1-24 saw excelled in cutting super duplex and flexible risers - materials that traditional shears can’t handle.

Furthermore, Decom’s innovative approach to reducing seabed dredging time by modifying the saw’s clamps reduced dredge time from 3.5 hours to just 30 minutes.

Established in the United Kingdom in 2011, Decom is an R&D specialist focusing on the design and fabrication of cutting solutions and innovative decommissioning equipment, with a growing reputation for providing complex deep water project solutions.

Decom Engineering Managing Director, Sean Conway, said, “The C1-46 Chopsaw is a remarkable piece of subsea engineering which was designed, developed, and deployed in under six months, specifically for this North Sea decommissioning campaign.

“This project underlined our commitment to engineering innovation and underlined our credentials for pushing the limits of what’s achievable in subsea decommissioning. To efficiently cut through a submerged 1,042mm reinforced concrete coated pipe is not without its challenges, but the C1-46 was more than up to this difficult task.

“It’s been a valuable learning experience and the performance of the C1-46 Chopsaw sets the benchmark for going on to roll out our technologies which offer multiple benefits to contractors and operators engaged in complex subsea decommissioning projects.”

The C1-46 Chopsaw has been designed to cut tubulars and other materials up to 46” diameter and is able to cut a wide range of materials, including inconel alloys, duplex and concrete.

It can be operated in water depths of up to 2,000 metres, has the ability to cut in any orientation, and is capable of multiple cuts per blade (20-100), resulting in large cost savings and increased efficiency. Blade changes are efficient and safe and the chopsaw can be supplied set up in a number of configurations and settings to suit project requirements.
