As the focus on environmental sustainability has never been more prevalent across all industries than it is right now, the race is on to find long-term renewable solutions to the climate crisis.  Operators across the globe are trying to make their innovations in the oil and gas industry as green as possible, but that is not an easy stepping-stone to overcome.

Geothermal energy could be the answer so many are looking for. It is a method of clean energy which bridges the gap between the oil and gas industry and renewable energy sources in order to reach net zero. The US has already increased federal funding by millions of dollars in 2022 alone to widen the scope of geothermal projects up and down the country, tapping into the underutilized potential beneath our feet.

A key area of interest within the geothermal industry is that of repurposing end-of-life oil and gas wells. Geothermal companies can turn these assets back into active wells, only producing a slightly different end-product, negating the need for decommissioning services and the associated costs.  Operators can turn their liabilities into profitable assets at a quarter of the cost while producing green energy.

In spite of the benefits associated with geothermal, there are a number of issues holding the industry back from becoming a mainstream alternative. For one, the extortionate upfront costs associated with starting geothermal projects from scratch prove a wall too vast to climb in most instances, as well as the technological challenges that present themselves when working with temperatures of this calibre.

Nevertheless, advanced methods and technologies are working at mitigating against the challenges posed by geothermal extraction, using expertise from the oil and gas industry to finesse already existing drilling equipment in order to marry the industries together to be able to harness a green energy source born from an oil well.

The omens for the offshore decommissioning market are looking positive as the industry prepares for 2023 and all that it has in store.

While a turbulent geopolitical environment has caused market fluctuations over the last few years (with Covid restrictions giving way to war in eastern Europe), a healthy oil price has been enjoyed through most of 2022, which is expected to settle in short- to medium-term. In addition, the pandemic revealed more than ever the pressing concerns around the fragile nature of our environment and has spurred the energy industry to promote sustainable practices wherever possible. In the case of the latter in the offshore world, there has been a renewed focus on decommissioning responsibilities, to ensure operators leave their stomping grounds as tidy and climate-friendly as possible.

Such concerns have been expounded by developments in Australia where the ongoing decommissioning of the Northern Endeavour FPSO (and the controversy around the trailing liabilities attached to it) has pushed this issue even more to the fore. The understanding of the forthcoming decommissioning wave has never been so developed, and the perception that we must get ahead of this, lest we get swept away by it, is sharp. By example, a recent report by Offshore Energies UK indicated that around the UK more than 2,000 North Sea wells are to be decommissioned at a cost of around UK£20bn. OEUK Decommissioning Manager, Ricky Thomson, said, “The UK’s decommissioning sector is snowballing and will continue growing for years to come.”

Fortunately, a healthy oil price and an ever-growing demand for oil and gas is filling the coffers of operators across the globe, making the burden of end-of-life activities easier to bare. Owing to these developments, industry reports are indicating that the global offshore decommissioning market will experience a strong growth in the immediate and long-term future. One report published by Visiongain, for instance, has forecasted that the market (which it valued at US$10.275bn) will grow at a CAGR of 6.5% between 2023 and 2033.

The opportunity to capitalise here is a tantalising one, with Thomson adding that with right government support the decommissioning challenge can be turned into gain, with the potential to create thousands of jobs. Indeed, many in the industry are not ignorant of this opportunity but are making moves to capitalise on this potentially lucrative market. At the end of 2022, for example, Harbour Energy, ConocoPhillips, Spirit Energy and Repsol Sinopec formed a well decommissioning collaborative initiative in conjunction with the Net Zero Technology Centre (NTZC). The initiative will enable new technologies to be trialled and tested in collaborative field trials enabling faster, lower-cost trials and wider industry adoption.

So, while no one knows for certain what 2023 will hold for the decommissioning sector, the strong position it has started the year in is a positive sign for its future growth and development in years to come.

As the oil market fluctuated more than it has in over a decade due to the fragile global developments that have occurred over the last few years, decommissioning and abandonment services in the Gulf of Mexico are facing a turbulent future as demand skyrockets.

As the restrictions eased after the Covid-19 pandemic, the world opened up again, bringing with it a tidal wave of demand, and due to the tightened restrictions put in place all over the Gulf to meet the needs of a sustainable future, the industry became gridlocked in a chain of bureaucratic laws and the increasing costs of labour and equipment.

Limited crews and equipment are only the tip of the proverbial iceberg as the ‘boomerang’ asset problem has started to cause havoc around the Gulf. With the law stating all operators, past and present, are liable for the decommissioning costs regardless of how long they owned the asset, mixed with the skyrocketing rates of inflation and equipment, the costs presented to operators may be insurmountable. The Fieldwood bankruptcy, which was finalised in 2020, is still sending waves around the Gulf, increasing the scope of work of up to 1,000 additional wells.

It's not all doom-and-gloom however, as opportunities for third party operators to shoulder the costs are becoming more prevalent. Operators who can’t afford the increased costs and scope of work in the given time frame can sell their assets to outsourced organisations who take full responsibility in carrying out decommissioning services. For the next few years, the Gulf is expected to continue riding the decommissioning wave until the spike in demand has dropped significantly.

The scope for decommissioning services in the GOM region is exponential, and is predicted to keep on rising, creating a haven for oil and gas operators. As long as the scope of work doesn’t outweigh the resources available, the Gulf is set to be in a very desirable position in the years to come.

At the recently concluded Offshore Well Intervention Gulf of Mexico conference, representatives from Caltex Oil Tools provided a detailed presentation of a recently concluded damaged wellhead repair project where the company utilised new technology and methodologies to successfully bring a well back online.

Since bursting onto the subsea scene in 2018, Caltex has become an established solutions-focused business which provides rentals, services and bespoke engineering capabilities for subsea operations. In the case of the latter, the company and its affiliates offer a range of services including equipment rental to support vessel and rig-based pre-commissioning, controls, completions, intervention and decommissioning activities; consultancy services with experts specialising in business development, sales, remote technologies, subsea controls, diver and diverless interventions, vessel based IMR operations, and emergency response repairs; as well as engineered solutions where it specialises in unplanned emergency response requests to developing transformative technical solutions.

The project that was presented at OWI GOM began when a major operator contacted Caltex over an offline well which had visible damage to the VX profile, FX profile and isolation sealing surface. Knowing Caltex’s extensive capabilities, the operator sought the company’s immediate help to intervene and bring the well back online. In turn, Caltex responded by developing a custom solution for machining the inner wellhead profile to remove the damaged surfaces.

It was in November 2021 when Caltex first began work on the project, with an initial concept to remove protruding materials and polish damages. According to Carter Kacal, Project Manager at Caltex, it was shortly after this, in January, when the project began to grow and the scope developed from what was originally perceived. After analysis of damage, their plans involved to machine the new ID .25’’ beyond the last damage, increase the ID of the wellhead by 0.125’’ and machine a 30° lead-in bevel at top/bottom of the increased ID.

This involved the development of a tool with the goal to machine a new ID of the damaged wellhead to tight specifications which also incorporated an automated system featuring closed loop controls and independent electronic actuator controls. From January onwards, Caltex swiftly developed Software (in just 15 days) and tested the tool to perform the required work before travelling to the manufacturer of the wellhead to perform an SIT at the beginning of March.

The technology utilised in the solution delivered by Caltex, according to Kacal, included a real mix of field-proven to new technology, resulting in a bespoke solution. It included three electronic actuators, an RPM sensor, subsea control units, a localised subsea power bank and an optical communication link connected through the ROV and controlled from the surface.

Kacal commented, “The results of the SIT were extremely positive, better than we could have expected, and well within the specifications we needed to be which is shown in the table.”

“We needed to be within 0.005'' concentricity and we achieved 0.002'' which was great. And then the surface finish that was well below what it needed to be as well. The goal (measured in Ra) was to be 111 Ra or lower. And so you can see there the average of the three numbers [on the table] is around 46. The only thing missing there is the results on the bevel cut. So we needed to cut a bevel as well as machine new diameter. We needed to be 30°, we were at 26°. This was a little steeper than we needed to be, but still successful nonetheless. From that everyone was happy to go offshore and we felt comfortable as well.”

Indeed, little time was wasted in doing so as, by the middle of March, the tool was offshore and ready to perform. Kacal continued, “We had a timely mobilisation with no downtime for the tool. We performed the operation in five days (from mobilisation to demobilisation) which included less than 24 hours operation of the tool itself. Then, once we pulled it off and actually tested the wellhead, everything was successful and eventually the well was able to be brought back online.”

For a job that began in November and had to contend with workscope changes along the way, it was a remarkably quick turnaround for the company which was ultimately successful. Kacal remarked that, alongside the timeliness of the operation, what worked very well was the automated system with closed loop controls alongside the performance of the tungsten carbide tool tip. He added that given slightly more time they could have spent more time developing and optimising the tool, however this did not overtly affect the performance and it has given the company confidence that they could deliver another project of similar scope and time effectively again.

“If there's ever an opportunity, we'd love to be able to try our hand at it again because we've proved it, we've developed it. At the moment I would say many people just don’t really know that is out there and no one really discusses if they have a damaged wellhead or not. So we want to show, with this example, that this technology is available and we have the ability to remediate the wellhead with a less invasive strategy than what is currently out there. At OWI GOM we had some interested discussions around this and people seemed definitely interested so we shall see what the future holds.”

C-Innovation (C-I) and Grand Isle Shipyard, LLC (GIS), two strategic oil and gas industry partners, have been awarded a plug and abandonment contract by Helix Alliance Decom, LLC, to provide pre-feed services for the decommissioning of three offshore platforms for a major deepwater client.

In Phase I of the project, C-I provided ROV services to deliver marine water inspection and integrated the data within MODS software to provide live operations for the client operating fixed leg platforms in 165-200 ft of water. The GIS Aerobotics Drone Division provided aerial inspection services. The joint technical innovations aim to determine the current condition of the wells and the facility, enabling the timely and cost-effective decommissioning of the wells, platform and jacket for each of the three platforms.

The partnership harnessed its technology to offer increased safety margins. All of the inspections were able to be completed via line wireless transmission from the back of the boat within a connex box without requiring the deployment of personnel on ropes.

Michael MacMillan, Operations Manager, C-I, stated, “The equipment used took very little time to mobilise and provided subsea operations in a safe and efficient manner while using a limited number of personnel. The ability to launch this type of ROV from almost any asset not only allows operations to be efficient but also mitigates safety risks while practically eliminating the traditional risks associated with the launch and recovery of an ROV.”

DaCoda Bartels, GIS Aerobotics Division Manager and Pilot, said, “The GIS drone can safely operate from up to 100 ft away from the asset as we have the camera stabilisation technology to zoom in on an area of interest. Most of these areas are not accessible by human personnel. We are able to live stream the drone's camera view in real time to make informed decisions on the spot. It’s a super fast and super safe alternative, where the only potential risk is to the equipment rather than the personnel.”

MacMillan added, “Our partnership with GIS enables C-I to continue to demonstrate our flexibility to provide resources and equipment in a non-traditional scenario. The availability of equipment and personnel for these types of scopes is more important now than ever, due to the demands of today’s market.”

PanGeo Subsea, a subsidiary of Kraken Robotics, has been awarded a US$5mn contract by Couvillion Group for assistance with a decommissioning project in the Gulf of Mexico.

In 2004, a storm induced mudslide caused an offshore jacket to topple which has since been lying on the seafloor 150 metres down, with subsea conductors buried in around 60 metres of mud. PanGeo will use Acoustic Corer, its high-resolution sub-seabed imaging technology, to identify where the conductors are located in the debris field to provide valuable information for the plugging and abandonment of the well.

The campaign will start in Q2 2022 and will last for 90 days – representing the largest Acoustic Corer project undertaken by the company to date.

Moya Cahill, PanGeo’s CEO, said, “The Acoustic Corer delivers a unique solution to the industry that has been tried and proven by the Couvillion Group in a demonstration project in 2019. We are truly excited to return to this site and work with the Couvillion team to complete a full site investigation of the debris field.

Couvillion Group’s CEO, Timmy Couvillion, added, “We believe that PanGeo has the key to unlock the unknowns below the seafloor that will ultimately enable a successful plug and abandonment of the well.”
In addition to the debris survey, PanGeo has been issued a letter of intent for a multi-million Acoustic Corer campaign of 50 days for an offshore wind farm in the Baltic where it will be imaging boulders in the sub-seabed.
