In its latest operations update, British independent upstream oil and gas company, Serica Energy, announced that its investment plans for the Bruce and Keith Light Well Intervention Vessel (LWIV) campaign is on track to take place between March and May 2024.

This follows previous campaigns in 2022 and 2023, which have delivered low-cost incremental production. The intervention is expected to restart production from the Keith field this year following successful preparation work on the Keith subsea facilities carried out in 2023. Additional well interventions from the Bruce platform are scheduled for the second half of 2024.

Besides well work on the Bruce and Keith fields, investments in 2024 include four wells in the Triton area (Bittern B1z sidetrack, Gannet E GE-05, Guillemot North West EC1 and Evelyn EV-02). The start date of the B1z sidetrack is set in March 2024. This well and the subsequent three wells are scheduled to take about three months each, meaning that drilling will continue into 2025. Serica has also exercised an option to keep the rig for a further well following completion of the fourth well in the programme (EV-02).
Serica is maturing plans for two infill wells on the Bruce field too with the aim of drilling in 2026.

Abandonment costs in 2024 are forecast to be about £14 million (pre-tax) net to Serica. These will be incurred mainly on the final decommissioning of the Arthur field, situated in the UK Southern North Sea, which was held by Tailwind Energy.

Reflecting on Serica's investment focus on enabling maximum production like from the Bruce and Triton assets, Mitch Flegg, Chief Executive of the company, said, "Production in 2024 is expected to be higher than in 2023 with guidance between 41,000 boe/d and 48,000 boe/d for the year. This reflects a range of outcomes in a year of significant activity including the speed with which the scheduled drilling and well work deliver incremental production.

"Serica's strategy of investing in its assets continues to be central to our record of consistently achieving high levels of reserves replacement, combined with increased levels of production. We are looking forward, therefore, to the start of the four well Triton area drilling programme in March, with the benefits of added production expected to start coming through in the second half of the year. During 2024 there is also an extensive programme of interventions in both platform and subsea wells on the Bruce and Keith fields. The objectives include re-establishing consistent production from the Keith field.

"In addition, Serica has a healthy portfolio of potential new projects. This includes the possible developments of the Buchan and Belinda fields, which offer the prospect of further replacement of produced reserves and incremental production from 2026 onwards. Our plans for drilling two Bruce infill wells, the first new wells on the field since 2012, are progressing and, during the next eighteen months, we will be participating in the Parkmead operated Skerryvore exploration well situated in the UK Central North Sea. As a UK taxpayer, Serica will benefit from tax relief for its share of the associated development and exploration costs.

"Serica is extremely well placed, therefore, to continue its track record of replacing reserves and increasing production. This platform has been achieved while maintaining a very strong balance sheet, which is both the result and enabler of our strategy to invest and grow organically and through disciplined M&A."

Backed by the Ministry of Economic Affairs and Employment and Salon Kaukolämpö Oy, Lounavoima is developing a geothermal heat well storage at its waste-to-energy (WtE) plant at the Lounapuisto circular economy park in Salo.

Following good test run from the first well, three additional wells are now being constructed. The final heat well is expected to be completed by the summer of 2025. 

Upon completion, the WtE plant will have six geothermal heat wells with a combined output of 6MW.

Waste heat produced by the WtE plant is stored at a depth of more than 2 kms in the geothermal heat wells to cover the district Salo's heating requirements during the winter.  

The first well which was tested last winter runs 1,600-metre-deep, producing 450 MWh of energy from January to March.

A second heat well, which is undergoing tests, was drilled in the autumn of 2023 and a third was drilled in the winter of 2024. Its pipework will be completed in the late summer. 

Finnish company Geomachine Oy deployed new drilling equipment which were specially designed for the exploration of the heat wells, achieving a target depth of 2,000 metres. The heat pump process was delivered by Calefa Oy.

Once all the heatwells are brought onstream, the six new geothermal heat wells will have a combined output of as much as 14 GWh a year, which is equivalent to the annual heating need of approximately 700 single-family homes.

“The heat well production will always be used first if the district heat output of the WtE plant isn’t enough. This allows us to primarily replace the need for starting oil heating plants and, in many cases, we can also avoid the need to start a backup power plant,” said Lounavoima and district heating company Salon Kaukolämpö's Managing Director Petri Onikki.

“We have such top expertise here in Finland. Even though the new technology development project has not always gone smoothly, the results have exceeded our expectations. The geothermal heat wells have a multiplying effect on heat production in Salo,” said Onikki. “The project is a successful example of concrete circular economy work at Lounapuisto,” he added.

Shell UK Ltd has signed a contract with Mermaid Subsea Services Ltd to utilise the offshore company's services for a multi-year engineering, preparation, removal and disposal (EPRD) well head severance (WHS) project in the North Sea.

Planned in three annual batches, the first phase of the decommissioning project is scheduled to begin later this year. The WHS solution will be delivered by a bespoke vessel for which Mermaid will be accumulating key stakeholders accross the supply chain. 

The initial campaign will involve the removal of well head protection covers from the sea floor, before lifting them to the surface for transportation onshore.

The well head flow base structures will then be retrieved using specialist tooling.

The final activity will cover well head severance and recovery operations, for which bespoke underwater cutting tooling and techniques will be deployed by Mermaid.

Each stage of the project will be followed by clearance of debris, as well as seabed and over trawl surveys where necessary. All the recovered materials from the project will be put to reuse and recycling. 

Milestone contract

Scott Cormack, Regional Director for Mermaid Subsea Services (UK), said, “This a milestone contract for Mermaid and we are very grateful to Shell for putting their faith in our team. We look forward to kicking off work this year.

“The North Sea is on the cusp of a multi-decade decommissioning boom and Mermaid plans to be front and centre of that with our bespoke solutions and leading expertise.”

The Ministry of Energy has awarded Equinor the Albondigas and Kinno licenses in the North Sea for CO2 storage development. 

Considered important building blocks for developing the Norwegian Continental Shelf into a leading area for CO2 storage in Europe, each of the licenses are expected to have a storage capacity of 5 million tons of CO2 annually.

"We are very pleased to see the Norwegian authorities have made new CCS storage acreage available for exploration and that we have been awarded these two licenses. We see that demand for CO2 storage is increasing in several countries, and it is crucial to bring forward new CO2 storages quickly, so that we can offer industrial solutions that can support large scale decarbonisation of hard-to-abate industries in Europe," said Grete Tveit, Senior Vice President for Low Carbon Solutions in Equinor.

Equinor expect 4-8% real base project returns for its early phase CO2 storage business, and further value uplift potential when commercial markets are developed.

Equinor is maturing a ship-based solution and a massive pipeline to connect industrial emissions in Europe with storage opportunities at the Norwegian Continental Shelf. The planned pipeline named CO2 Highway Europe will have capacity to transport 25-35 million tons of CO2 per year from Belgium and France.

The Albondigas and Kinno licenses will serve as additional storage opportunities to the Smeaheia storage license which was awarded to Equinor in 2022. Smeaheia will be used as the anchor storage for this pipeline development.

Equinor is also about to complete the first phase of the Northern Lights CO2 transport and storage facility together with Shell and Total Energies. It will be ready to receive CO2 by the second half of this year.

"Scale-up of CO2 transport and storage is essential to meet the interest and demand for this type of services. Gaining access to more CO2 storage capacity aligns well with our ambition of having 30 to 50 million tons of CO2 transport and storage capacity per year by 2035," said Tveit.

The UK National Geothermal Centre (NGC) has been launched to accelerate the UK geothermal sector and enhance the role it can play in decarbonising the UK’s future energy mix.

With funding from the Net Zero Technology Centre (NZTC), Durham University, SHIFT Geothermal, and The Reece Foundation, the NGC aims to support research and innovation, develop expertise and drive the creation of a policy, regulation and investment framework which enables geothermal advancement. It will drive collaboration between government, industry, and academia, promoting the integration of geothermal energy into the future renewable energy mix as a low carbon option for heating homes and industries, and power generation.

The geothermal sector has the potential to meet 10GW of the UK’s projected heating demand and 1.5GW of the anticipated electricity demand by 2050. Geothermal expansion could create 50,000 jobs for the future and result in an annual reduction of 10 million tonnes of CO₂ emissions.

Significant step

Nigel Lees, chair of the NGC, said, “The launch of the National Geothermal Centre today represents a significant step in realising the opportunities that geothermal energy provides the UK. For several decades there has been a growing and meaningful contribution to our understanding of geothermal potential in the UK, yet we remain in the nascent stages of development with pockets of knowledge and expertise.

“The Centre will embrace and build on this, working collaboratively with all stakeholders to ensure a common understanding of the opportunities and challenges whilst giving a consistent voice and advocacy to fully unlock the geothermal potential in the UK and play a crucial part in the delivery of our net zero ambitions.”
