To resolve methane emissions challenges during a decommissioning programme, Interwell P&A's RockSolid turns out to be an ideal solution

The company had addressed such an issue during a Canada operation, when it was able to shut in a shallow methane gas source ejecting around 0.55 cu/m per day by installing a gas-tight barrier at 773mKB inside a competent caprock.

Effective sealing solution

The emission was initially isolated and later stopped, enabling a smooth delivery of the decommissioning programme. It was a result of a surface casing vent flow (SCVF) issue in a well, where two different gas sources were identfied following pre-intervention logging. The installation of the RockSolid barrier ensured that it was effectively sealed from the roots, allowing ongoing research to address the shallow source. This was shut off by the installed RockSolid that replaced the casing and cement, obstructing any hydrocarbon flow inside the borehole. As gas pockets above the barrier had bled off, the well decommissioning programme was carried out unhindered.

The RockSolid remains a sustainable plugging alternative.

The Gulf of Mexico (GOM) is a critical region for offshore oil and gas production, with operators increasingly focusing on mature fields to meet energy demands sustainably.

As new field discoveries slow, industry leaders are directing resources towards maximising the efficiency and recovery of existing assets.

According to industry insights, the GOM accounts for a significant portion of global oil production from mature fields, where advanced well intervention techniques are proving instrumental in maintaining output.

With many platforms and wells in the region reaching the latter stages of their operational lives, optimising recovery has become a cost-effective and environmentally sound approach.

Unlike new developments, interventions on mature fields leverage existing infrastructure, minimising both capital expenditure and environmental footprint.

New technology

Technological advancements are at the heart of this strategy. Companies like Baker Hughes are introducing tailored solutions such as their Mature Assets Solutions programme, designed to enhance production efficiency while addressing sustainability concerns. Light well intervention technologies are also increasingly deployed in the region, enabling cost-effective maintenance and recovery improvements.

The well intervention market in the Gulf of Mexico is projected to grow steadily as operators shift their focus from exploration to maximising output from existing fields. Industry reports indicate increased spending on well interventions, with the region becoming a hub for innovation in this domain.

Challenges remain, including ageing infrastructure and tightening regulations. However, these also present opportunities for service providers and technology innovators. By addressing these issues proactively, operators in the GOM are positioning the region as a leader in sustainable offshore production.

The focus on mature fields in the GOM reflects a broader trend in the energy sector: achieving a balance between meeting current energy needs and progressing towards a more sustainable future. This approach ensures the Gulf remains a cornerstone of global offshore production while contributing to environmental and economic goals.

Proposed legislation would direct the US Department of the Interior to submit an annual public report to congress on the status of decommissioning offshore oil and gas wells, platforms and pipelines.

The Plug Offshore Wells Act was introduced by Oregon Senators Ron Wyden and Jeff Markley before the end of 2024 and seeks to address the growing threat of abandoned offshore oil and gas infrastructure to marine ecosystems and the environment.

“Neglected oil wells off our coasts are a ticking time bomb that threaten our coastal communities and environment in Oregon and nationwide,” Wyden explained. “It’s unacceptable that Big Oil has dodged responsibility to clean up drilling sites and pollution. This legislation will provide the data needed to hold Big Oil accountable and protect the public as well as our waterways and marine life."

“Orphaned wells are an environmental catastrophe waiting to explode," Wyden added. "They pose the possibility of massive damage to the ocean by leaking oil and gas and must be addressed quickly.”

In submitting the new legislation (which was co-sponsored by Senators Peter Welch and Ed Markey), the office of Wyden quoted a recent study by the US Government Accountability Office (US GAO) which expressed that more than 2,700 wells and 500 platforms in the Gulf of Mexico are overdue for decommissioning. The study also found that the Bureau of Safety and Environmental Enforcement and the Bureau of Ocean and Energy Management are unable to effectively enforce decommissioning deadlines and financial assurance requirements.

Avoiding decommissioning disaster

The study by US GAO recommended steps congress could take to address the current backlog of overdue decommissioning requirements, including the instituting of new reporting requirements from the Interior Department to Congress on the status of decommissioning.

This is what the Plug Offshore Wells Act aims to do while also reducing financial burdens on taxpayers by increasing oversight of Big Oil companies and holding them accountable for the full terms of their offshore oil leases. The proposed legislation – which is supported by numerous organisations including the Center for Biological Diversity, Earthjustice, Natural Resources Defense Council, Oceana, Ocean Conservancy, Ocean Defense Initiative, and the Surfrider Foundation – has now been officially introduced to congress and has been referred to the Committee on Energy and Natural Resources.

In one of his final acts before Trump returns to the White House, US President Biden has implemented a ban on new offshore oil and gas drilling across most of America’s coastline.

The decision from the ‘lame-duck’ President, was taken in light of the “environmental and economic risks and harms that would result from drilling” that “outweigh their limited fossil fuel resource potential” according to an official announcement on The White House website. As such, more than 625 million acres of the US ocean has been protected from drilling, principally the entire U.S. East coast, the eastern Gulf of Mexico, the Pacific off the coasts of Washington, Oregon, and California, and additional portions of the Northern Bering Sea in Alaska. These have been protected from future oil and natural gas leasing in a bid to safeguard coastal communities, marine ecosystems, and local economies from oil spills and other impacts of offshore drilling.

For President Trump – who has recently named a fracking executive as his Energy Secretary – it presents an immediate challenge and one that he has promised to address as soon as he comes to power. In a radio interview, the President-elect said he has the “right to unban it” and he would do so at the earliest opportunity.

However, this may not be so simple. As outlined by Reuters, the Lands Act does not grant President’s legal authority to overturn prior bans and any attempt to do so would likely require an act of Congress. Biden’s bid to protect the marine environment could, therefore, not be as futile as Trump imagines and could bring a temporary halt to his plans to unleash domestic fossil fuel production.

Fortunately, for oil and gas companies who are eager to maintain production rates but are now unable to fall back on the tried and tested method of drilling, production enhancement through well intervention can offer a timely solution. Certainly, the longer the ban on new drilling stands, the more attractive this method of sustaining rates will become, presenting a potentially lucrative market and unique opportunity for those involved in delivering well intervention services.

According to the analyst from Verified Market Research, the Gulf of Mexico oil and gas decommissioning market is estimated to reach a valuation of US$43.31bn in 2031

Stricter environmental restrictions have hastened decommissioning activities, with 2,300 non-producing wells scheduled for plugging and abandonment by 2025. The US Department of Interior’s annual report states that environmental compliance expenses for decommissioning grew by 35% between 2020 and 2023, reaching an average of US$2.8mn per platform. 

Many Gulf of Mexico operators face enormous financial risks due to their decommissioning obligations. As infrastructure ages and becomes more difficult to destroy, the expected expenditures for decommissioning range from US$40bn to US$70bn. Furthermore, the decommissioning process has inherent environmental dangers, especially if not carried out effectively. 

The deepwater segment is estimated to hold the largest market share during the forecast period, with the deepwater Gulf of Mexico showing tremendous untapped resource potential, attracting major investment and interest from operators. Technological developments have increased the efficiency and safety of deepwater operations, making it more economically viable to extract resources from deeper oceans. Subsea engineering and remote monitoring system innovations make decommissioning operations more efficient, lowering costs and timescales. These technological advancements increase the appeal of deepwater projects, resulting in more growth in this segment.

Case studies highlighted in the Offshore Energies UK Offshore Decommissioning Report 2024 have highlighted the importance of offshore engineering and preparatory work for safe and cost-effective outcomes in decommissioning projects.

OEUK cites AF Offshore Decom’s experiences with a bridge-linked flare stack, where extensive preparatory work, particularly from the platform complex, significantly reduced the time required for the heavy lift vessel (HLV) in the field. Additionally, by focusing the preparatory activities during the winter months, the team was able to optimise the use of the HLV for the summer, thereby enhancing operational efficiency.

In another case highlighted in the report, extensive preparatory works facilitated a smooth and effective removal of a major platform. Comprehensive helicopter surveys and a thorough engineering phase were undertaken, minimising unexpected issues during the main offshore removal campaign. This was followed by an HLV campaign when a crew handled the topsides preparations along with smaller modular lifts. A second HLV campaign included a large integrated modularised steel frame lift and an efficient jacket lift. The structures were then transported onwards to AF's environmental base to be dismantled and recycled onshore.

The phased execution helped to mitigate risk and allowed for detailed engineering and interface management, which was an important part of the project.

Optimising offshore operations for decommissioning projects in this way can make a substantial contribution to keeping costs down. This is critical in the Gulf of Mexico, where operators face spiralling decommissioning costs. Findings from a recent study published in Nature Energy showed that there are around 14,000 unplugged oil and gas wells in the Gulf of Mexico, with the process of plugging and decommissioning these wells estimated to cost around US$30bn.
