Global well integrity and production optimisation firm, Coretrax, has created a casing integrity solution for a major North Sea operator which is said to eliminate the need for a casing string to be replaced.
The project saw a team of three engineers identify and mobilise the trouble zone, and install a short patch on a casing section of the well affected by corrosion.
To pinpoint the trouble zone, the engineers deployed its CX-RTP (retrievable test packer), a heavy-duty service packer used to set and pressure test a range of depths to identify the area in need of patching.
Following the identification of the trouble zone, the company deployed its ReLine HYD expandable casing patch to isolate the area and regain well integrity without the costs associated with replacing the casting.
Western Hemisphere President at Coretrax, Keith Bradford, said, “Our team of engineers worked collaboratively to identify how we could combine technologies from across our portfolio to effectively meet our client’s objectives. We mobilise products from CORE, our expandable tubular product line, and packers from our AEON line which we use for plug and abandonment solutions.
“The outcome was a great success and allowed our client to not only continue operations with minimal disruption or downtime, but also potentially saved costs on replacing the entire casing string.”
The project was completed in five days.
Argeo Robotics AS, a fully owned subsidiary of Argeo AS which develops robotic and digital solutions for the ocean space, has been granted a patent from the Norwegian Industrial Patent Office for a subsea electromagnetic remote-sensing system.
The company has developed a portfolio of electromagnetic source and receiver systems for Autonomous Underwater Vehicles (AUV), Underwater Intervention Drones (UID) and ROVs. This patent protects Argeo’s exclusive services with the products Argeo Whisper and Argeo Discover.
Argeo Whisper is an AUV and ROV system developed for localising and tracking buried pipelines as well as detecting buried objects in a decommissioning survey. It can also be used for detecting unexploded ordnances.
Argeo Discover is an application or detecting, delineating, and characterising deep sea mineral deposits or other conductive objects below the seafloor utilising an electromagnetic source integrated in an AUV or ROV.
The company has developed an electromagnetic source that is designed to operate down to 6,000 m water depth. This technology enables ultra-high resolution characterisation of minerals that has previously not been possible. With Argeo Discover added to Argeo’s AUV and ROV sensor portfolio, Argeo is in a position to provide effective ultra-high resolution data acquisition for both larger regional and detailed local exploration over large areas with deposits utilising its fleet its AUVs rated to 6,000 m water depth.

The company will provide high resolution environmental and potential marine mineral resource assessment in addition to an advanced dual-AUV operation. Argeo will retain show and marketing rights for the data and present the results using its digital visualisation platform, Argeo SCOPE.
The recycling operation of Curlew, an FPSO vessel, has started in Vats, Rogaland, this week, with the 235 m-long ship loaded-in by a float-over and subsequent site move operation.
The vessel will now be cleaned, dismantled and at least 97% of it will be recycled.
This is the first time this type of vessel has been recycled in Norway. The production vessel, Curlew, was operated by Shell UK, and produced oil and gas from the Curlew field in the UK sector in the North Sea. The chosen decommissioning solution known as a float-over-float-in operation has never been used on such a large scale anywhere in the world. The contract was awarded to AF Offshore Decom through competitive tendering, and includes engineering, preparatory work, dismantling and recycling.
Dismantling and recycling of offshore installations and ships is an important part of the green transition. Here, Norwegian industry and engineering expertise have developed solutions that are at the forefront of the industry. This provides tangible evidence of the circular economy given nearly 97% of the ship can be used as raw materials in new production, with steel being used as rebar in new buildings, and all hazardous waste is taken out of the system and disposed of in a responsible manner.
“This is a very complex logistics project with significant marine operations. We are proud that we can carry out such complicated operations in a safe and environmentally sound manner," said Lars Myhre Hjelmeset, Executive Vice President for Offshore in AF Gruppen.
The production vessel Curlew has been in operation in the UK sector of the North Sea and was transported to the facility at AF Environmental Base Vats in Rogaland in 2020. The preparations on the FPSO have been ongoing at AF Environmental Base for some time, and the float-over-float-in-operation was completed this week. Now the ship has been transported ashore in the largest single offloading of a production vessel that has been carried out in this way. The hull is now safely located on the quayside at AF Environmental Base Vats, ready for cleaning, dismantling and final recycling. These activities will start immediately and continue throughout 2023.
“We have considerable experience in recovering offshore installations and floating production vessels is another area where our expertise and approach is both relevant and internationally recognised. Complex operations like this show that Norwegian offshore and engineering expertise helps set the standard for safe and environmentally sound solutions," commented Hjelmeset.
Saab Seaeye, a leading underwater e-robotics company, is assisting in the decommissioning of an oil platform in Angola – the first to undergo this work in the country.
EQS, an environmental quality services company, is leading the project with help from a Saab Seaeye Falcon underwater robot that has been deployed to help transform the platform into an artificial reef.
Chief Technical Officer at EQS, Carlos Rodrigues said, “By operating the Seaeye Falcon and all its related capabilities, EQS is supporting its aim to fulfil specific works in a safe and cost-effective manner delivering accurate and relevant information.”
The Falcon is assisting in the survey and mapping of all underwater components, including checking the wellhead, pipelines and the surrounding maritime environment.
Baseline environmental conditions are determined by taking water and sediment samples at several stations and at different depths, focussing on biological matter, namely zooplankton, phytoplankton, and benthos.
Significant marine growth already exists throughout the structure with abundant marine life already in the area for populating the rig when toppled on its side to become an artificial reef. Once decommissioning is complete, a series of surveys will be scheduled to monitor the evolution of marine growth on the newly created reef.
EQS selected the Seaeye Falcon for its ability to handle an array of cameras, sensors, tooling and complex data gathering systems that include a digital multi-frequency profiling sonar.
Future work involves clearing an area of fish nets, restoring platform signalling and marking, positioning of signal buoys and confirmation of pipeline locations along with the surveys to monitor marine growth.
Treating and removing scale build-up within a tubing retrievable subsurface safety valve (TRSSSV) can be problematic, costly, and timely. For scale dissolvers to work effectively, they require extended soak periods to penetrate the scale.
To meet this problem, Oilenco has introduced the Oilenco Bullheading Jetting Sleeve which combines traditional soaking methods with a ‘jetting’ action, targeting scale dissolvers directly at critical components of the downhole safety valve, agitating the scale as well as soaking it?
Combining two tried and tested technologies, the new tool delivers optimum scale treatment results by using a repeated method of scale soak and targeted jetting.
Requiring minimal well intervention, this innovative product is designed to precisely target critical areas within the TRSSSV using a ‘jetting’ action to optimise distribution and efficacy of scale treatment. Designed with a minimum of two jet subs, the system is preconfigured to target key mechanical components within the TRSSSV before being deployed into the well on slickline.
Unique to the Bullheading Jetting Sleeve is the multi jet sub system. Each jet sub consists of an array of micro nozzles that create a 360⁰ jetting pattern. By positioning two or more jet subs at key locations within the safety valve (i.e. flow tube, exercise profile, flapper, etc.), scale dissolver can be precisely targeted at these critical areas.
Between each jet sub there is a flowrate sensing valve that directs fluid to either the upper or lower jet sub depending on the velocity of the fluid passing through it. When pumping stops, the jetting stops. When not jetting, the Bullheading Jetting Sleeve reverts to a conventional soak arrangement allowing the scale dissolver to soak into the scale. As soon as surface pumping is reintroduced, the jet subs become active and intense fluid agitation can recommence.
With constant replenishment of fluid, the system maximises performance of the scale dissolver in the most efficient time frame. Every drop of dissolver can be targeted at any critical area of the TRSSSV where scale build up could be affecting the functionality of the valve.
An ideal dual technology solution when scale build-up is identified as the likely cause of a TRSSSV not functioning, the Bullheading Jetting Sleeve (patent pending) is an innovative addition to the Oilenco safety valve management portfolio, re-establishing the integrity of a well and allowing operations to continue.
Well-SENSE, a downhole sensing specialist, has deployed its FiberLine Intervention (FLI) technology at a large carbon capture and storage (CCS) facility, in an industry-first application.
FLI has already been well-proven in a variety of seismic, acoustic and temperature monitoring applications in the oil and gas sector and has just completed its first geothermal well survey for Eden Geothermal in Cornwall.
The fibre-optic monitoring system has since been deployed for a leading integrated energy operator in Australia and marks the first time that fibre has been used to survey live CCS wells and reservoirs.
The new application in the carbon sequestration sector provides a safe, low-risk monitoring solution in a highly corrosive CO2 environment where traditional intervention solutions are often detrimentally affected.
The energy operator employed FLI in a field trial to study well integrity, CO2 flow characterisation and plume movement within the reservoir. FLI’s distributed temperature sensing (DTS) enabled assessment of the reservoir zones, while its distributed acoustic sensing (DAS) simultaneously acquired vertical and passive seismic data.
Annabel Green, CEO at Well-SENSE, commented, “Our FiberLine Intervention system was selected by this leading operator, to be evaluated as a potential alternative to the use of wireline production logging tools. Our system’s advantages include its extremely compact rig-up, much lighter surface pressure control equipment which uses a static rather than a dynamic seal and a simpler deployment method compared to conventional techniques. FLI also uses a bare fibre that is impervious to the corrosive effect of CO2, which helped to make this intervention possible.
“Several challenges were overcome efficiently, including the requirement to leave the fibre in the well for four days with exposure to strong fluid cross flows, the requirement for immediate Cloud data transfer from the wellsite to the operator’s technical centre and servicing a remote wellsite near live infrastructure. We are delighted that operations were performed incident free with no major NPT events and that our unique technology provided valuable, high-quality data from multiple wells.”
With an ever-increasing demand and healthy oil price appearing to reach relative stability, much of the oil and gas industry has thrived across 2022, despite the tumultuous geopolitical environment threatening to upset Covid-19 recovery efforts.
As supply from Russia continues to reduce, European countries are preparing to fill the gap by boosting production while balancing their environmental commitments. To help walk this tightrope, there are calls for operators in the North Sea to invest more into offshore well intervention an opportunity which could see it emerge as a cornerstone of the North Sea industry.
With more capital available for spending on such activities and a plethora of shut-ins, experts have highlighted how the industry is also presented with a blank canvas in the North Sea for testing new technologies. The eventual implementation of these could really help tip the balance in the risk versus reward scale and take down a potential barrier preventing future interventions.
While stimulating production is the most pressing concern at this time, increasingly influential regulators are ensuring that the decommissioning wave on the horizon is not removed from gaze. As climate concerns continue to mount and the ageing region advances in its maturity, there is growing pressure for the industry to expand their attention on end of life activity. This is work that will not simply disappear and, with soaring profits rolling in from high demand and healthy oil price, there are calls for operators to take advantage of this boom and get ahead of their liabilities – a trend which could open up the market for companies offering project management, engineering analysis, data collection, downhole tools, etc within this workscope.
