New green partnership boosts heat recovery from geothermal wells

26 Jul 2021

A leading international energy consultancy, service and software provider has recently launched a new division which applies technology, expert knowledge and learnings gained from delivering specialist safety and integrity management, drilling and well engineering and asset management solutions to the oil and gas sector into carbon reduction initiatives.

Harnessing decades of experience and expertise, Add Energy is well positioned for advising and supporting companies in their quest to develop greener energy solutions, in a safe and efficient manner.

With an already established track record in supporting companies design, develop and operate CCS projects, hydrogen energy, biomass power, solar and geothermal energy, Add Energy has committed to a number of investments to maximize the value they can deliver to their clients seeking to transition to greener energy solutions.

Today, Add Energy announces the completion of a frame agreement with Rock Energy Group Limited, a specialist Norwegian geothermal technology provider. This agreement builds on a long-standing existing working relationship to repurpose experience and technology previously developed for oil wells to extract geothermal energy and provide sustainable heat sources.

Rock Energy’s patented multilateral open hole well configuration connects the deep lateral wellbores together into a closed flow loop for circulation of water. The water heats up as it flows through the laterals and the heat is extracted on return to the surface by heat exchangers. This technique and well configuration boosts recoverable energy from the well which can be constructed in any hard rock country and placed near the consumers giving it huge international potential.

The move is likely to lead to the creation of new jobs within Add Energy as the popularity of the technique gains momentum not only in Norway but also in other locations where there is a particular focus on transition of oil and gas recovery to geothermal and carbon capture storage projects.

Rock Energy and Add Energy’s relationship began in 2013, when the companies worked together to conduct feasibility studies to explore the ability for geothermal wells to provide heat to various industrial complexes just outside Oslo, Norway, as well as office locations within the city. In recent months, both the concept and the relationship have grown from strength to strength, and the new agreement is seen as pivotal in facilitating exploration of additional, deep geothermal wells projects across the globe.

Commenting on the recent developments for Add Energy’s Decarbonization and Energy Transition division, Terje Løkke-Sørensen, Chief Technical Officer at Add Energy said:

“By tapping into our pool of expert experience and knowledge, ranging from well integrity to risk management and blowout contingency planning, and combining this with Rock Energy’s cutting-edge geothermal technology, I believe we are uniquely positioned to help companies achieve their carbon reduction goals in the safest and most efficient way possible.”

Commenting on the renewed cooperation, Jan Edin Evensen, Chief Executive Officer at Rock Energy Group said:

“We are very pleased with Add Energy providing engineering services and support to Rock Energy's own in-house expertise in drilling and completions".
