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.

40 years since the launch of its first subsea test tree system, Expro, a leading energy services provider, has remained at the forefront of subsea landing string technology.
The first 10ksi subsea test tree assembly (SSTTA) was created for an exploration and appraisal well project for Hamilton Brothers in the North Sea in 1983. Several of its SSTTA technologies have been on a first to market basis and have helped to progress the sector’s capabilities over the years. Expro has now undertaken more than 3,000 subsea deployments in exploration and appraisal, completion, and intervention applications, and remains a global leader in large-bore SSTTA solutions.
Other subsea well access major milestones Expro has achieved over the years have included the introduction of the first 7 3/8” 10ksi horizontal tree completion landing string system; the launch of the industry’s first 6 ¾” high debris SSTTA system; the release of the first large bore 6 ¾” 10 ksi subsea electro hydraulic control system; unveiling the first 6 ¾” 10ksi dual bore and mono-bore subsea test tree offshore; revealing the first 15ksi 6 1/8” horizontal tree SSTTA and electro-hydraulic control system; and the development of 7 3/8” 10ksi high debris SSTTA.
The evolution of subsea test tree assemblies has allowed the company to expand into the open water well intervention market through the introduction of both riser-based and riser-less well intervention solutions. Such success and dedication to subsea well access application even earned the company the accolade of Intervention Champion of the Year at the recently-held OWI Global Awards 2023.
At the company is showing no signs of building on its successful history. In a bid to continue this history, it has sought to boost its subsea capabilities by acquiring PRT Offshore, the only company to offer a complete Hook-to-Hanger solution enabling comprehensive well completions, interventions, and decommissioning services from surface to subsea. The acquisition enables Expro to expand its portfolio of cost-effective, technology-enabled services in the North and Latin America region and accelerate the growth of PRT Offshore’s surface equipment offering into the Europe and sub-Saharan Africa and Asia Pacific regions.
“At Expro, we’ve been first to the market with many of our subsea test tree assembly products and, as future technical challenges arise, we believe that with our customer-bespoke solution philosophy, we’ll continue to be at the top of the subsea test tree application,” remarked Graham Cheyne, Expro’s Vice President of Subsea Well Access.
“From starting in 1983 supporting operators in the Norwegian North Sea, we’ve become a global player in all parts of the world, supplying fully integrated technologies and services from surface to seabed – the hook to hangar concept. The subsea test tree market operates in the full well lifecycle – from exploration and appraisal through to abandonment and decommissioning while continually looking to improve our delivery and operational performance, and service quality to our global client base.
"Whilst leading in this market for over 40 years with many first to market technologies we are committed to delivering the new technology requirements of tomorrow in order to meet our customer needs whilst maintaining the high level of service quality and customer care.”

Chevron Corporation has announced that for its fourth quarter 2023 it will be impairing a portion of its US upstream assets due to continuing regulatory challenges.
Primarily in California, the challenges in the state have resulted in lower anticipated future investment levels in its business plans according to the statement. It expects to continue operating the impacted assets for many years to come.
In addition, the company indicated it will be recognising a loss related to abandonment and decommissioning obligations from previously sold assets in the Gulf of Mexico as companies that purchased them have filed for bankruptcy and the company deems it probably and estimable that a portion of the obligations will revert to it. As such, the company expects to undertake decommissioning activities on the assets over the coming decade.
Currently, Chevron is now in the process of finalising the financial impacts of these actions and will likely treat them as special items, excluded from adjusted earnings. These actions are currently estimated to result in non-cash, after-tax charges of US$3.5bn to US$4bn in its fourth quarter results.

Offshore Network’s latest Global Well Intervention Report delves into the highly-prosperous global market and analyses the growth of operators utilising well intervention practices as the focus across the industry is shifting towards end-of-life activities and reaching environmental targets.
Assessments issued by Rystad Energy suggest that 17% of the world’s wells will undergo intervention processes by 2027, accounting for 260,000 wells globally. Spending within this market has already seen a surge and is likely to amount to US$58bn by the end of 2023, representing a significant growth of 20% since 2022. Climate consciousness has played a predominant role aiding the growth as mounting pressure is building across the industry to limit environmental footprints, with global companies seeking to make intervention an integral pillar within their business strategies.
In November 2023, COP28 witnessed Saudi Arabia launch its landmark Oil and Gas Decarbonisation Charter (OGDC) wherein 50 companies who represent 40% of the global oil and gas market thus far have signed up to the global pact to speed up climate action initiatives and are committed to become net-zero by 2050. However, it is not just the call for fast environmental action that is driving the intervention market, but the global increase in energy demand is also playing a vital role. According to the International Energy Agency, annual oil demand is expected to grow from 285.7 mboe/d in 2021 to 351 mboe/d in 2045, with oil set to retain a 29% share in the energy mix.
Increasing production rates is still a major priority across the industry, and a factor that must be balanced with the growing need to minimise carbon footprints. Well intervention practices are proving a key avenue that companies across the globe are turning their heads to, from expediting resources from the more veteran regions like the North Sea and the Gulf of Mexico to introducing more of these practices to ‘newer’ regions such as the Middle East and West Africa.

Offshore Network’s newly released Global Offshore Decommissioning & Abandonment Report tracks the growing need for end-of-life activities that is becoming an increasingly pertinent issue across the world.
While decommissioning has its roots as far back as the 1960’s, it was only towards the end of the century, under mounting environmental sentiment, that national bodies and the community began engaging with the issue more acutely and discerning what this will mean for the industry’s future. Time and resources dedicated here have drawn the curtains further back, and the more that is revealed, the more daunting the decommissioning task has become.
In 2021, IHS Markit predicted that global offshore decommissioning spending could reach around US$100bn between 2021 and 2030, a staggering 200% increase compared to the previous ten-year period. In light of this, the information services provider asked whether the world was entering “a decade of offshore decommissioning” as it reacted to the data that suggested nearly 2,800 fixed platforms and 160 floating platforms could be decommissioned in that period, alongside more than 18,500 wellheads, 2,850 subsea trees and 80,000 km of offshore pipelines and umbilicals. Looking further ahead, the Energy Industries Council further predicted that this cost of decommissioning would continue to rise beyond that, hitting the US$200bn figure within the next 20 years.
Offshore Network’s unique report charts the rise of the decommissioning market across the globe, providing analysis on this within each of the key offshore oil and gas regions from the more mature regions of the North Sea and Gulf of Mexico, to those that are less far along in this journey such as West Africa.

The University of Texas at has received a US$4.9mn grant from the US Department of Energy (DOE) to conduct research on two potential climate change solutions around the Earth’s subsurface: the storage of carbon dioxide and the generation of energy.
A team of UTEP researchers will lead a multi-institutional team in accelerating climate change solutions. Other contributors will come from Florida State University, the University of Utah, Sandia National Laboratories and Alma Energy LLC. Together, they will target solutions for two DOE objectives, reducing carbon dioxide in the atmosphere and enhancing the effectiveness of geothermal energy capture.
Son-Young Yi, Ph.D., an Associate Professor in the Department of Mathematical Sciences, is the grant’s Principal Investigator and forms the UTEP contingency of the team alongside Co-PIs James Kubicki, Ph.D., a Professor in the Department of Earth, Environmental and Resource Sciences and Zhengtao Gan, Ph.D., an Assistant Professor in the Department of Aerospace and Mechanical Engineering.
The researchers will create computational models, using machine learning algorithms, that can help the clean energy industry reduce carbon dioxide in the Earth’s atmosphere and create a reliable means of accessing geothermal energy.
“There is a bevy of interactions taking place underground which influence the amount of energy that can be extracted from a particular location and the rate of production that a particular location will offer over time,” Gan said. “Our team will work with an industry partner to create computational models that can mitigate the exploration risks and help players in this industry identify the best areas for geothermal energy extraction.”
According to the team, the increased efficiency may result in greater quantities of energy extracted and sustained rates of production, which will hopefully translate to a more accessible and affordable way for Americans to power their homes.
“This is an exciting opportunity because crossing scales and putting together a picture of geochemical processes is a grand challenge in subsurface applications,” Kubicki said. “The potential to bring geothermal energy to the El Paso region and to help address carbon dioxide removal from the atmosphere is a dream come true.”
One method being researched for storing excess carbon dioxide is geologic carbon sequestration, which is the injection of the gas in underground geologic formations, such as saline aquifers – reservoirs of salt water that are located deep beneath layers of rock. A drawback to this approach is the possibility for the gas to seep, or leak, back to the surface and re-enter the atmosphere, Yi said.
“Our computational models will analyze the behavior of carbon dioxide across different scales, from the microscale to the macro scale, so that we can simulate and predict how long carbon dioxide will stay in the underground rock formations,” Yi said. “The work is ambitious as no model exists yet that has been able to link data about carbon dioxide’s behavior across scales, but if we’re successful, our models will help the clean energy industry understand the long-term evolution of the injected carbon dioxide and better identify optimal locations for carbon dioxide injection with respect to minimizing leakage.”
