OWI MED 2022 is back as a live event after last year’s inaugural virtual launch. The conference will be held in Athens, Greece, on 20 September 2022. The hottest talking points within the Mediterranean and North Africa region, along with the latest well intervention intelligence from the region will be discussed at the event.
One of the key discussions at the conference will be learning how implementing new digital systems can result in more cost-effective and efficient well intervention and integrity processes. Operators can explore preventative maintenance efforts which can mitigate potential problems such as corrosion.
Contributing to this topic, will be Mustafa Adel Amer, well integrity specialist from BAPETCO. He will throw light on well integrity management, right from a production obstacle to a production booster. Mustafa will review surface-controlled subsurface safety valve (SCSSV) failure statistics in BAPETCO over the period 2010 to 2018. Mustafa will also explain the assessment of risk of failing in SCSSV and analyse wells criteria to define safe well operation with failed SCSSV.
Mustafa will be holding a panel discussion on ‘value of well integrity in reducing methane emissions’. It will seek answers to what the global industry can do or is currently doing to bring down its methane emissions from oil and gas operations. The discourse will explore the role of well integrity to reduce methane emissions for existing wells still in production and analyse whether well integrity has an impact in reducing methane emissions in abandoned wells.

Seafarer, belonging to vessel-based subsea well construction and intervention services provider AKOFS, has just completed mobilisation for an upcoming three-well campaign as part of the five-year contract for well intervention for Equinor on Nowegian Continental Shelf (NCS).
The work has been performed at the Myklebust Yard in Norway. The OneTeam model implemented by AKOFS, was responsible for completing an intensive mobilisation without any serious safety incidents.
Following successful riser-less interventions since second half of 2020, Equinor and AKOFS have mobilised for a riser-based campaign using coiled tubing through an option in the contract. The AKOFS Seafarer has proven to be an extremely efficient vessel for riser-less interventions year round on NCS, thanks to its unique set-up, size and lay-out as well as the OneTeam model implemented by AKOFS and its operating partners Archer, WellTec and IKM Subsea. Utilising its flexibility, a high pressure work-over riser system has now been mobilised and added to the vessel together with a coiled tubing spread and fluid return treatment system.
The AKOFS Seafarer is now en-route to Equinor-operated fields Norne, Åsgard and Statfjord where well objectives will include scale, sand and debris removals, perforations as well as installation of plugs and screens.
Heerema has been awarded a decommissioning contract by Woodside Energy that includes the integrated engineering, preparation, removal, and transport of the Nganhurra riser turret mooring (RTM).
For the project, Heerema will remove the RTM from the Enfield field, located approximately 52 km northwest of Exmouth in Western Australia, by lifting the structure in one piece onto a barge and transporting it o Henderson or another suitable Australian port for dismantling, and recycling or reuse.
Jeroen van Oosten, Heerema’s Chief Commercial Officer, commented, “We are proud to be Woodside Energy’s contractor of choice for removing the Nganhurra RTM. This contract represents our first decommissioning project in Australia and although Heerema has a long history of safely and sustainably removing offshore structures from the North Sea and Gulf of Mexico, we are very excited to continue our responsible decommissioning operations in Australian waters.”
Heerema is looking forward to taking an active role in Australia’s decommissioning ambitions. The removal and subsequent reuse or recycling of offshore infrastructure is an essential final step in the lifecycle of oil and gas infrastructure and aligns with our company values of responsibility, sustainability, and contributing to a circular society.”
Serica Energy plc, a British independent upstream oil and gas company with operations centred on the UK North, has provided an operations update outlining its successful well intervention campaign on the Bruce Field.
Serica’s first ever light well intervention vessel (LWIV) campaign, part of the company’s ongoing plan to add value and extend the life of its Bruce facilities, has now concluded without any safety incidents or environmental issues.
The initial well (Bruce M1) was re-entered for the first time since 1998 and, after a successful scale removal and water shutoff, a significant reperforation and new perforation campaign was executed with the well returned to production.
Rates from the well have since increased from around 400 boe/d before intervention to more than 1,800 boe/d.
A similar programme was followed on the second well (Bruce M4) and production rates for the well increased from around 450 boe/d to more than 2,400 boe/d. The results from these two wells are at the upper end of the range of expectations and it is expected that there will be an uplift to independently assessed reserves.
This programme has increased confidence that further uplift can be achieved from future well interventions. Subsequently, plans to perform similar interventions on other Bruce and Keith wells, both subsea and from the platform, are now being accelerated.
Serica’s production performance in 2022 is benefitting from the significant investment in the Rhum R3 well reintervention, the Columbus development project and now the LWIV campaign. Serica’s average net production in July has averaged over 29,150 boe/d and YTD average net production is 26,832 boe/d.
Mitch Flegg, Chief Executive of Serica Energy, commented, "I am delighted with the significant progress that Serica has continued to make during 2022. The impact of the substantial investment programmes undertaken in the last three years has seen increased production levels providing responsibly sourced gas to the UK domestic market, protecting security of supply, and reducing the UK’s reliance on imports as part of the transition to a lower carbon future.
“Serica has no debt, limited decommissioning liabilities and with growing cash reserves is well positioned to continue to invest in further projects and other opportunities to add shareholder value. We have just completed a well intervention campaign on Bruce that has boosted net production by over 3,000 boe/d and provides further evidence of the value in Serica’s assets that can be realised through measured and expert operatorship.
“Operations have also commenced on the North Eigg exploration well with potential for transformational results, while we are now accelerating further well intervention work on Bruce and Keith following the success of the recently completed campaign.”
At D&A AUS 2022, Craig Costello from ASX Listed (T3K) TEK-Ocean Energy Services, provided an in-depth exploration of the company’s work within the abandonment space, explaining how it has inspected, refurbished, revalidated and recertified vintage well intervention equipment and assisted in decommissioning vintage oil and gas wells.
Speaking about wells and well intervention equipment, he presented cases of petroleum production companies with vintage subsea wells. He added that some of those wells were past their design lives and have integrity issues – both known and unknown problems. “The construction and production of these wells provided jobs for many decades. But it’s now time for these legacy wells to be plugged and abandoned, safely and efficiently,” he added.
In many cases, the required intervention equipment isn't readily available via OEMs – often because it has been retired. So this legacy vintage equipment, when it is available, requires revalidation, recertification, refurbishment and adaptation to the specifics of the project, Craig explained. Much of the legacy equipment is said to be redundant tooling.
There's an expectation from those who have worked on these wells for many years and from the broader community that the wells are abandoned safely and in a timely manner. “Increasingly, we're seeing NOPSEMA publishing directions and notices in regard to the decommissioning of wells, setting deadlines, and publishing information papers on decommissioning.”
Moving on, he presented three case studies to the audience, the first being the abandonment of some subsea wells by a semi-sub rig – Esso’s Blackback abandonment in the Gippsland basin; second was another subsea well set from a jackup rig: Esso’s Seahorse & Tarhwine abandonments; and lastly the Intervention Riser System assessment on Laminaria Corallina.
He informed that there were a lot of common themes for the three projects, one of them being that these are vintage subsea wells, with both known or otherwise unknown issues due to the lack of communication with the wells.
In all these cases, TEK-Ocean was able to provide alternative means to monitor the wells and barriers in both open water and drilling riser configurations.
Other common threads on these projects were:
• Intervening on wells past the original nominal design lives
• The vintage legacy equipment requiring revalidation, recertification and refurbishment
• Integrity issues on the wells
• Planning, innovative solution ideation and engineering.
Focusing on the first case study – the Blackback well abandonments – Craig said there were 20-year-old wells that had been shut for almost 10 years without any communications. “They have been lost from the Mackerel platform. So they didn't know the status of those wells. TEK-Ocean was selected as the lead subsea provider for that project for a turnkey solution to abandon the wells, requiring innovative approaches to get communications back to these vintage subsea control modules,” Craig added.
Hence, the scope of supply that TEK-Ocean provided for the solutions included sourcing equipment, conducting risk assessments and implementing a barrier philosophy for operational phases. The customer had supplied the vintage tree running tool and TEK Ocean recertified that.
“Re-establishing communications on these wells was a project in itself. Several pre-rig campaigns were executed to survey the assets, confirm the subsea interfaces functionality and to reduce the cost of the programme. This included ROV inspections, testing, opening and closing valves, cleaning, and debris removal."
Craig said establishing communications on those wells did take some effort as several of them that had not been attended to in a very long time and the equipment wasn’t readily available. “So TEK-Ocean was tasked with carefully assembling together a working system from three partial and broken systems that were available, with limited support and documentation from the OEM. This was successfully achieved.”
Craig informed that the Blackback wells were first attempted to be killed in 2010 via a bullhead operation from the Mackerel platform that was successful in two of the wells but it was later found that one had some internal leaks. “TEK-Ocean was not involved in the original bullhead operations but in the light of diagnostics, it was found that there was pressure on the wellhead above the master valves. Also, in 2015, communications were lost, so those investigations were a part of the 2019 campaign. The customer supplied a tree running tool, a 1980s vintage piece of equipment required for recertification and refurbishment. This recertification was achieved via crosschecking materials, part numbers, compatibility and suitability.”
One risk assessment flagged up that only one tree running tool had been provided. This was identified as a single point of failure and required de-risking because multiple runs of the tree running tool were going to be required. De-risking was achieved via a saver- sub approach that was designed, manufactured and project managed by Tek-Ocean for an integrated solution.
Moving to the second case study, he showed Seahorse & Tarhwine, which is in slightly shallower water in the Gippsland basin with 46 metres of water, and the abandonments were performed from a jack up rig. These vintage wells were drilled in the early 80s and then completed later that decade, but had been shut for five or six years, so they hadn’t been checked for quite some time. “The scope of supply in this case was a full subsea project management service again, using TEK-Ocean ISO accredited integrated management system, including all aspects of project management and engineering. The project execution plan was prepared including rig interfacing, barrier and emergency shutdown philosophies. Again, there was a TEK-Ocean managed pre-rig ROV campaign, including subsea cleaning, testing, to de-risk the rig campaign,” he added.
TEK-Ocean supplied and repaired all the equipment, again except for the tree running tool. In this project, the intervention riser system used was the TEK-Ocean dual bore riser system and this can operate down to 200 metres.
It was again a tight preparation and delivery schedule for this project. However, TEK-Ocean was able to mobilise in good time ahead of the required date set by the customer again with HSE performance and an operation during the peak COVID lockdown period in Victoria.
The third case study was the recent inspection and condition assessment of 1990s vintage Laminaria Corallina IRS. The inspection and condition assessment were carried out for both the upcoming suspension of the wells and for the future abandonment.
While concluding, Craig said that TEK-Ocean has a deep and broad knowledge of installed infrastructure throughout Australia particularly in the Carnarvon & Gippsland basins and that the company can support across all different project types. “These case studies demonstrate the recent projects that have been done in the last couple of years for major operators in the Gippsland Basin. We can help you achieve your cost and schedule goals on subsea well abandonments, and help you maintain a strong HSE performance record. TEK-Ocean is now recognised as a leading Australian company in the decommissioning space.”

Well decommissioning specialists Well-Safe Solutions have signed an agreement to plug and abandon (P&A) 14 wells on the United Kingdom Continental Shelf (UKCS).
The deal is the first scope agreed for the Well-Safe Defender semi-submersible rig, which the company purchased in June 2022. The project, for an undisclosed value, will see the rig mobilising in March 2023 for approximately 250 days of work.
Neil Ferguson, Operations Director at Well-Safe Solutions, said, “This is a very exciting time for our teams, with a little over a month between Well-Safe taking ownership of the Well-Safe Defender and the signing of this contract with our latest client.”
According to the company, the Well-Safe Defender is currently undergoing a host of efficiency enhancements as part of its integration into the business as well as the completion of its recertification ahead of mobilisation in March 2023.
Gavin Robinson, Commercial Manager at Well-Safe Solutions, said, “We are delighted to assist our client, a leading European operator, with meeting their decommissioning obligations on these historic fields. Like the Well-Safe Guardian and Well-Safe Protector, the Well-Safe Defender is a dedicated decommissioning asset converted from a drilling rig. Clients benefit from a greatly reduced carbon footprint and quicker mobilisation times as a result, as no virgin steel is required for a new-build rig.”
“In addition to the clear economic benefits of this approach, we expect this work to generate approximately 60 new positions offshore, with several supporting roles also required onshore. This will take the total estimated headcount in Well-Safe to 330 people in early 2023,” Gavin added.
The contract announcement is the latest in a summer of growth for Well-Safe Solutions, which previously announced a well decommissioning contract with Ithaca Energy as well as a capital funding boost of more than US$59mn (£50 million) by new and existing investors.
Allseas has celebrated yet another major offshore milestone after completing the removal of Repsol Norge’s 30,000 tonne Gyda platform in a matter of days.
Pioneering Spirit delivered the platform’s jacket to Asker Solutions’ disposal yard in Stord, Norway, less than 48 hours after removing it from the southern Norwegian Sea. The latest job for vessel’s jacket lift technology is one of the heaviest ever, but well within the 20,000 tonne lift capacity.
The jacket was set down directly onto the quayside and reunited with it decommissioned drilling and production topsides. Aker Solutions expects to recycle around 98% of the facilities.
Split across two campaigns, Pioneering Spirit completed the removal, transport and load-in to the disposal yard of the entire Gyda platform, its 32 conductors and template in 12 days.
To facilitate removal of the jacket, the structure’s 24 foundation piles were cut below seabed level. Main hoist blocks suspended from the Jacket lift system (JLS) beams were connected to pre-installed rigging and the entire structure lifted and aligned with the lifting beams. As the jacket was vertically fabricated and installed, the structure could not sustain loading in the horizontal position during transport.
The solution of transporting the jacket in a near-vertical (60%) position, with interface supports and grillage made delivery of the complete jacket to the yard possible. Pioneering Spirit only requires days in the field to remove entire platforms and subsea facilities, eliminating the need for multiple trips and a support fleet. Saving time and reducing vessel operations to a minimum significantly reduces the vessel’s emissions footprint.
“Our mission at Allseas is to remain a frontrunner in the offshore energy market by pioneering ground-breaking technology to meet the industry’s ever-changing needs,” said Allseas President Edward Heerema. “The Gyda platform removal strengthens our reputation as a game changer in the industry. Again we have shown that Pioneering Spirit provides a significantly faster, safer, more efficient and sustainable option for the removal and installation of offshore facilities.”
The world’s largest construction vessel will now mobilise for further heavy lift commitments. These include further jacket removals, as well as installation of a major offshore wind transmission station and jacket in the German North Sea that will supply clean electricity to tens of thousands of homes.
In what has been a busy year for Pioneering Spirit, the vessel has already lifted and transported more than 90,000 tonnes of decommissioned and new offshore facilities for the offshore energy industry in 2022, deploying both its Jacket lift and Topsides lift systems.
The Offshore Well Intervention Latin America 2022 (OWI LATAM), which will be held in Rio, Brazil from 18-19 October, will host a presentation by Matthew Vick, Senior Subsea Wells Engineer from bp.
Attendees will have the exclusive opportunity to learn about the company’s riserless intervention campaigns in the Gulf of Mexico.
Vick will review the broad scope of well access equipment that can be utilised from a single vessel, including mechanical wireline, hydraulic via TRT, hydraulic via well service jumper hose and hydraulic via stimulation choke insert.
During the talk, he will explore an overview of the planning and execution of the campaign including well access, well integrity restoration, well surveillance, well stimulation and protection, and fishing.
OWI LATAM allows you to access new regulations and innovative LWI technologies to develop a best practice intervention strategy for production, integrity and P&A projects.
