ASCO, a UK-headquartered logistics and materials management company, has completed a contract with Onslow Marine Support Base (OMSB) in Western Australia in support of the offshore decommissioning sector.
Two radiation safety officers (RSOs) as well naturally occurring radioactive materials (NORM) and mercury monitoring and analysis equipment were mobilised to the OMSB site as per the contract. The RSOs delivered on-site training for NORM awareness, and monitoring for various hazards such as benzene, hydrogen sulphide (H2S) with a particular focus on NORM and mercury.
OMSB Chief Operating Officer, Andre Veder, said, “At OMSB
we believe all parts of the supply chain supporting the offshore decommissioning sector requires a robust focus on safety, efficiency and compliance. As part of this, OMSB proactively holds a range of licences including a radiation licence and associated management plan.
“To drive an effective and compliant outcome for the receival, handling and storage of potentially radioactive items, OMSB selected ASCO as its radiation specialist. ASCO’s international experience with radioactive items has allowed projects undertaken to appropriately manage the risks while not impacting the schedule of the works."
The project was led by senior RSOs John Davidson and Robin Small who helped to optimise the site, ensuring that supervised areas were set up correctly and any contaminated materials were properly managed and contained. The team enhanced OMSB's management plans and risk assessments, ensuring top-tier radiation management and site safety operations.
Australian decommissioning opportunities
While ASCO has been present in Australia for more than 13 years, this contract represents the first time it has delivered NORM services in the Southern Hemisphere, demonstrating its capability and establishes its credibility to operate in this segment here. According to ASCO, this will set the groundwork to confidently invest to further deliver large scale projects of this nature in the country and expects continues growth in the region as the decommissioning opportunities in Australia mount.
Lee Vettese, Business Development Manager - Environmental Services and Decommissioning at ASCO, added, “This contract signals significant growth for ASCO in Western Australia. Our work in the North Sea has led the way in global decommissioning activity for a number of years now and we’re excited to bring that experience to Western Australia."

Ahead of the D&A APAC 2024 Conference, set to open its doors in Kuala Lumpur from 12-13 November, Offshore Network has released its Asia Pacific Decommissioning and Abandonment Outlook which reviews the region’s current liabilities and the key players who are undertaking the oncoming decommissioning storm.
The countdown is on for Southeast Asia to stay ahead of what promises to be a prosperous decommissioning market in the decades to come. As many of the region’s upstream assets wave goodbye to their productive years, D&A liabilities continue to tally up meaning the once-distant thought of decommissioning is now firmly at the forefront.
According to Petronas’ Activity Outlook 2021-2023, within Malaysia there are more 3,000 wells in which 45% are idle, with over 500 scheduled to be permanently plugged by 2030. Wood Mackenzie has previously reported that Southeast Asia’s offshore assets, amounting of 2,600 platforms and a staggering 35,000 wells, will eventually need to undergo decommissioning services.
Due to the sheer scope of D&A work in the years ahead, emphasise is being placed on the growing need for knowledge sharing and collaboration throughout the region. With collaboration comes the implementation of innovative technology and more opportunities to reap prosperous results akin to those seen in the North Sea and Gulf of Mexico.

Allseas has reported that Brent Charlie topsides have been successfully delivered to Able UK’s Seaton Port in Hartlepool, UK.
Weighing more than 31,000 t, Brent Charlie is the largest single offshore topsides to be lifted, transported and delivered to shore, according to Allseas. It was initially removed in a single lift by the Pioneering Spirit, Allseas’ heavy lift vessel that is capable of lifting entire topsides of up to 48,000 t and 20,000 t jackets.
After being carried on the vessel to near-location, the topsides was transferred to the custom barge, Iron Lady, for the short tow to the Tees Estuary and onwards to the Seaton Port disposal facility.
Barge and topsides were grounded onto the grounding bed in the wet dock for the load-in. All safety checks complete, the former production platform was skidded onto Quay 6, designed specifically to distribute the weight of the heaviest topsides facilities.
Now delivered, the massive topsides will be decommissioned with as much recycled or re-used as possible. Able UK has achieved over 97% recycling/re-use rates on previously decommissioned Brent topsides Delta (24,000 tonnes), Bravo (25,000 tonnes), and Alpha (17,000 tonnes), and aims to match or exceed this figure for Charlie using its well-established supply chain.

Geothermal services provider DMT GmbH & Co. KG will be exploring geothermal potential in Münster for Stadtwerke Münster GmbH who commissioned the project as part of the 2030 decarbonisation strategy
The project will involve a large-scale 3D seismic measurement campaign before winter 2024/25, surveying the deep underground between 1,400 and 7,000 meters, covering the entire city.
"25% of the heat demand in Germany could already be covered in the long term, sustainably and CO2-neutrally using deep geothermal energy. The first steps to accelerate the heat transition with the help of deep geothermal energy have been taken. Now it is important to consistently use and roll out instruments such as exploration loans or insurance, national and international funding and accelerated approval procedures. This means that projects like the one in Münster can soon be implemented throughout Germany," said Maik Tiedemann, Chairman of the Management Board / CEO of DMT, and CEO of the TÜV NORD GROUP Business Unit Energy & Resources.
The campaign will see five vibrator fleets working in parallel, consisting of up to 18 vibro trucks and a measuring crew of around 80. Data collected from the campaign will influence further planning and implementation of the heat transition using deep geothermal energy in Münster and the associated decarbonisation.
"The upcoming measurements in the deep underground around Münster will provide valuable information to specify the agenda for the use of deep geothermal energy in the Münsterland and to define a roadmap for this project. With our recent acquisition of high-quality and state-of-the-art measuring instruments, we are also well prepared for the expected increase in orders," said Thorsten Müller, Head of Business Entity Exploration Seismic at DMT, who leads operational teams.

Electrocentrale București (ELCEN), one of Romania’s leading producers of thermal and electric energy, has signed a MoU with Sage Geosystems for the carrying out of a feasibility study for the implementation of geothermal technologies in the Bucharest district heating system.
The benefits of this collaboration are aimed at ensuring sustainability, innovation and efficient economic solutions for the future of centralised heating in Bucharest in an approach that is consistent with the national and European energy transition objectives.
Through the MoU, ELCEN will facilitate access to the relevant data and necessary infrastructure in order to carry out the study, and will contribute its technical expertise and specific operational knowledge to the centralised heating system within Bucharest. Sage Geosystems will perform the technical and geological analysis and feasibility study on the geothermal utilisation solution.
The aim of the partnership is to explore how geothermal energy can be implemented within the city the replace a fossil fuel-based thermal plant with a clean alternative. The first project is expected to generate up to 70MW of thermal power for a district in Bucharest, and upon its a success, will be expanded to other Romanian projects and cities.
General Director of ELCEN, Claudiu Crețu, stated, “We signed this Memorandum of Understanding to see how we can use the geothermal potential in the coming years for the heating of Bucharest as efficiently and sustainably as possible in a hybrid approach."
Cindy Taff, CEO and Co-Founder of Sage Geosystems, commented, “Sage is thrilled to be supporting Romania’s transition to clean energy and to introduce geothermal energy applications to its capital city.”

Offshore Network has released a new report on the Offshore Well Intervention Market in the Gulf of Mexico.
The new research comes ahead of the OWI GOM 2024 Conference arriving in Houston from 21-22 November. This is apt timing for it will closely follow after the US election – a significant event that will greatly affect the future of the offshore oil and gas industry in the region. The return of Republican candidate, Donald Trump, to the White House will likely herald a wave of drilling and a slackening of regulations rung tighter under the tenure of President Biden. However, should the Democrat nominee win, then the focus will likely remain on restricting further assets being created and greater emphasis on operators to fulfil the ever-growing decommissioning scope of work.
Regardless of this outcome, according to most market commentators, global demand for oil and gas is set to remain at least for the short-term, and likely for longer. With drilling becoming an increasingly distasteful option in much of the public eye, production enhancement to maintain rates and extend asset life is becoming increasingly attractive – if the recovery factor of mature assets is boosted by just 1%, then 2-3 years of additional consumption could be satisfied. These dynamics are creating a favourable outlook for the well intervention market in GOM, and service providers are looking to take advantage by bringing new technology into play of ever-increasing sophistication.

Perenco UK has completed a campaign of velocity string installations on five wells at the West Sole Charlie platform in the Southern North Sea (SNS), situated 70 km east of Perenco’s Dimlington terminal on the Yorkshire Coast.
The campaign was conducted by the Petrodec HAEVA rig and has delivered sustained production gains of around +5 MMscf/d, in line with expectations.
In a technical and commercial feat, the company completed ahead of schedule. Each of the wells are seeing improved production rates, running with 100% uptime, withouth the need for cycling. Two of these wells were brought online from scratch as they remained shut-in and were not producing.
The net effect is a new production rate for the West Sole field sustained above the 30 MMscf/d level. Recompletion using velocity strings is a proven technology in fields that are no longer producing at their original high gas rates.
In the case of West Sole, the original completion with 5½” tubings were no longer optimal, given the now partially depleted reservoir. Inserting velocity strings of narrower diameter helps to increase the fluid velocities, thereby sustaining production at lower pressures and allowing extension of field life. Perenco had previously deployed this technique to good effect in 2020 at the Hyde field and decided to continue with similar deployment at West Sole Charlie. Other SNS fields, such as Apollo, are also being evaluated for the same.
Significant production hub
Perenco UK SNS Managing Director, Jo White, said, “Demand for gas in the UK is set to remain high, so enhancing recovery from domestic gas fields is vital for both energy security and for improving overall emissions intensity. Local natural gas resources have a significantly lower carbon footprint than imported liquified natural gas (LNG), which today accounts for a high proportion of the balance of supply. West Sole was the first offshore natural gas field to be developed in the UK. Since 1967, it has delivered cumulative production of more than 2.2 trillion cubic feet of gas. It remains a significant production hub in the SNS offshore gas network, with potential for future development and tie-in of nearby gas discoveries. Through renewal and application of new technology a sustainable and productive future remains possible for decades to come for the West Sole field.”

Offshore Network has released the Wells Latin America 2024 Outlook that reviews the region's intervention and decommissioning drives, while considering the wave of new technology revolutioninsing the industry.
The push behind these industry innovations come from watchdog organisations such as the Brazilian National Agency of Petroleum, Natural Gas and Biofuels (ANP) or Brazilian Institute of Environment and Renewable Natural Resources (IBAMA), which make sure that exploration and production activities are being carried out in a responsible and sustainable manner.
In Brazil, Petrobras have approximately 500 well interventions planned over the next 10 years, and also a significant decommissioning workload, which it has outlined in its 2024-2028 strategic plan. To achieve these feats, the company is actively researching cost-effective means to go about the task. Petrobras has plans to introduce thermite melting delivery in its operations this year. If all goes well, through tubing thermite P&A (TT P&A) delivery is expected by 2026, and the company is eyeing up the prospect of adopting self-abandonment technology by 2030.
The region's growing well intervention industry is taking inspiration from North Sea, where companies such as BiSN and RockSolid are introducing fresh approaches to well services. BiSN’s wel-lok technology, for example, uses bismuth as permanent seal for P&A operations, while RockSolid uses organic well barriers, eliminating the need for rigs or heavy equipments.
Reflecting on these landmark industry transformations that are currently sweeping through the region, Wells LATAM 2024 conference promises fully-rounded discussions and engaging exchanges.

In an operational update from the SASB gas field well intervention programme, Trillion Energy International has noted the improved flow rates from the South Akcakoca-2 well.
“The fantastic response of South Akcakoca-2 once the water was lift off the perforations indicates that the reservoirs will produce the gas they contain once the water loading is removed. The wells are going to be perforated and monitored during clean up to evaluate the reservoirs response. The next phase of this project is to install the smaller production tubing (2 3/8”) to allow the wells to produce for a few years before water loading occurs again," Arthur Halleran, CEO of Trillion, said.
The South Akcakoca-2 well was perforated over the intervals 2319.5-2323.5 (4.0 m), 2339.6-2341.3 (1.7m) and 2411.1-2412.8 (1.7m) for a total of 6.4 m (all measured depth MD). Well hole pressure (WHP) was 86 psi before perforation, the WHP increased to 1046 psi.
The well flowed continuously from early 9 July, and by 10 July afternoon the flow rate was 0.70 MMcf/d with a WHP of 140 psi. By 15 July, the flow rate was 2.88 MMcf/d with a WHP of 318 psi.
Monitoring of the South Akcakoca-2 well will be continued until it hits a stable point.
The production characteristics indicated that perforating the new zones blew the water out of the well, while also implying that the reservoirs that were water-blocked are cleaning up and producing gas.
Guluc-2 well was perforated over the intervals 3512-3514.5 (2.5 m), 3749.5-3751.3 (1.8 m), 3770.7-3772.4 (1.7m) and 3781.6-3783.3 (1.7m) for a total of 7.7 m (all MD). WHP was 650 psi and increased to 1243 psi before settling to 1098 psi.
Guluc-2 will be flowed to clean the water and perforation debris out and be capable of gas production, however, it will then be shut in while South Akcakoca-2 well gas production stabilises.
The increase in the WHP during perforation indicates gas flowed into the borehole from the new perforated zones.
Updated flow rates have yet to be established for this well due to the ongoing testing of SA-2.
The perforation operation is currently continuing ongoing on West Akcakoca-1 well after which it will perforate the remaining pay in Akcakoca-3.
