As the recent well test on the State 36-2 LNW-CC-R well from Zephyr Energy's Paradox project reflected considerable well productivity, the company announced an updated Competent Person's Report (CPR) that was compiled by independent energy consulting and advisory firm, Sproule-ERCE International Limited
This acknowledgement has allowed Zephyr Energy to transition the Paradox project from appraisal to development, as the well test revealed high reservoir pressure, reservoir quality and liquid yields, leading to a significant boost in recoverable reserves across all reserve categories.
Based on the performance of the Cane Creek reservoir on 20,000 acres held within Zephyr's White Sands Unit, the CPR confirmed a 93-fold increase in Proved Recoverable Reserves (1P Reserves), demonstrating the site's scale and immediate production potential. It will be able to deliver 14.8 million net barrels of oil equivalent proved recoverable reserves, an increase from 0.16 million net boe in the 2022 CPR.
Speaking of the Paradox project, Colin Harrington, Chief Executive of Zephyr, said, "To date, we have drilled two successful, one-mile horizontal wells utilising different completion technologies and both demonstrated strong deliverability and expanded our completion design options for the greater field development. We have also gathered a substantial amount of data that will help inform future development plans. Furthermore, we have acquired significant infrastructure that will enable us to bring the project into full production, including gas gathering lines, plant infrastructure, permits and future water disposal wells, and we are close to securing gas export capacity. All this has been achieved at low development costs, especially when compared with many other new field startups of a similar size, and this infrastructure should enable accelerated project development once a suitable partner is secured. It should be noted that while acceleration of drilling activity and increased gas processing capacity won't change undiscounted free cash flow totals, they would enhance the current NPV-10 value of the project by bringing forward future cashflows."

Archer Limited, based in Bermuda, has announced plans to acquire Premium Oilfield Services, LLC, a US-based well services provider specialising in fishing and plug & abandonment (P&A) operations. Premium is known for its experienced workforce and strong service reputation with major oil and gas operators.
This move is part of Archer’s strategy to expand its presence in the Gulf of Mexico, where its combined client base with Premium covers over 80% of the projected $15 billion deepwater P&A and decommissioning market through 2040.
The US$20 million acquisition will be financed through a planned private placement. It is expected to close shortly after the placement is completed, subject to standard closing conditions, including financing.
One key benefit of the deal is Archer’s acquisition of a well-maintained fleet of fishing equipment valued at $35–40 million, which will cut rental costs and boost efficiency. The acquisition will create cost and capital synergies and is expected to deliver a full return on investment within two years.
Financially, the deal is seen as highly accretive. Archer anticipates a 5% boost to annual EBITDA and an 8–10% rise in annual cash flow, based on pro-forma results and synergies. This supports the company’s strategy to increase shareholder returns and reduce debt.
This acquisition builds on Archer’s strong M&A track record. Since 2023, the company has invested around $90 million in bolt-on acquisitions, generating approximately $30 million in EBITDA, reflecting a multiple of around 3x EV/EBITDA. Archer aims to continue targeting accretive, synergy-driven deals in the well services space.
Failure to decommission offshore oil and gas infrastructure on time and in compliance with requirements poses safety, environmental, and financial risks.
Failure to maintain offshore oil structures, while leaving them idle and unused can degrade these structures and pose safety risks to employees and regulators visiting the site. Moreover, a lack of maintenance can restrict access to the platform, requiring them to undergo expensive repairs and further contributing to delays in decommissioning operations. Moreover, poorly maintained structures lack appropriate lighting which can behave as a navigational hazard by disrupting ships that are operating in the area.
Delays and noncompliance with decommissioning requirements can give birth to financial risks, particularly to the US government and taxpayers. In most cases, post-bankruptcy decommissioning liabilities in federal waters have been met by co-owners, previous owners, or new owners. However, some instances have had the government having to use taxpayer dollars to pay the costs of cleaning up after delinquent oil companies. When a current leaseholder is unwilling or unable to pay decommissioning costs, federal regulators can, under a system known as 'joint and several liability,' require any or all co-owners or previous lease-holders to pay the decommissioning costs for that infrastructure. For big oil companies with operations in the Gulf of Mexico, these 'contingent liabilities' could amount to two to six times the amount of their direct decommissioning liabilities. Oil companies often do not report these contingent liabilities on their balance sheets.
Some observers have voiced concern and doubt about the strength of federal joint and several liability regulations and the government’s ability to force previous lease-holders to pay decommissioning costs as more offshore oil and gas facilities reach the end of their productive lives.
Stagnant oil and gas infrastructures in the Gulf of Mexico can be vulnerable to deterioration and decay, thereby becoming a source of pollution. This is because detereoration and decay of these structures can lead to oil spills due to a failure of tanks and pipelines. The resulting release of corroded metal into the water can cause chronic pollution. Generally, offshore wells that are either improperly plugged or unplugged are found to become a source of pollution along with leaky or shallow-water wells or abandoned platforms that could be significant sources of greenhouse gas emissions.
While oil spills from idle or unused oil and gas infrastructure are unlikely to discharge high volumes of material, even small amounts of oil are toxic to marine organisms—from plankton to marine mammals—and can cause adverse impacts to their health or their ability to reproduce.
Moreover, deteriorated infrastructures can be prone to hurricanes and other major weather events, which have been increasing in frequency and intensity due to climate change. The Gulf of Mexico is subject to powerful hurricanes that can destroy equipment such as oil storage tanks, move subsea pipelines, or even topple entire platforms.52 Any of these events can trigger oil spills, either directly from the damaged equipment or through impacts to connecting or adjacent facilities.
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.
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.

The agreement also extends joint operations into newer regions such as Oregon, Washington, New Mexico, and across the border into Mexico.
Energy services provider Expro has completed a well cement placement project for a prominent operator from the US, Gulf of Mexico, delivering an inner-string cementing on a subsea well's 22" surface casing in a water depth of approximately 2,000 m in the Mississippi Canyon area
When integrated with Expro’s other well construction technologies, the company’s innovative Cure technology range, including SeaCure, QuikCure, and CoreCure, offers a comprehensive package for ultimate cement placement and provides a complete 'head-to-shoe' solution.
Expro's Cure technologies allowed the operator to overcome ongoing offset well challenges. These included prolonged wait on cement (WOC) periods when transitioning directly from the jet string to the 22" surface casing, and tasks associated with drilling out a 22" shoetrack.
Jeremy Angelle, Expro’s Vice President of Well Construction, commented, “Our integrated cementing solution helped save approximately 18 hours of cement related drill-out, clean-out, and WOC time when compared to offset wells. By using our Cure technologies, we removed the requirement for a shoetrack to be left in the casing string, helping to avoid previously experienced cement sheath-related challenges. In addition, the QuickCure solution reduced WOC time. This latest project highlights Expro’s commitment to provide solutions that empower our clients to overcome operational challenges and achieve excellent results.”
The Cure technology range was added to Expro’s portfolio of cost-effective, innovative solutions within the company’s well construction product line as part of the Company’s acquisition of DeltaTek in February. The DeltaTek range of low-risk open water cementing solutions help increases clients’ operational efficiency, delivers rig time and cost savings, and improves the quality of cementing operations.
The global offshore well intervention market is set for a period of extended growth in light of stable oil prices forecast in the short-term, maintained oil demand in the medium- and possibly long-term, and ever-increasing environmental pressures.
Globally, spending on well intervention is on the rise with Rystad Energy predicting an increase by almost 20% in 2023 to take the total tally to US$58bn. This is just the start of a forthcoming surge with 17% of wells predicted to go through the intervention process by 2027.
North America accounts for 64% of the total wells ready for intervention by 2027, according to Rystad, giving rise to the dramatic potential of the market in the Gulf of Mexico. According to BSEE, there are approximately 1,885 active production platforms on the OCS with more than 60% older than 25 years.
This is leaving operators grappling with the need to maintain production rates while also dealing with ever-ageing infrastructure, with mounting regulatory pressure increasing the need to address decommissioning obligations. In facing this conundrum, an increasing amount of well intervention activity is highlighting the importance of this service as a means to address both sides.
As new technological innovations become more viable and the understanding around methods such as light well intervention build, the market will only advance in stature, suggesting it will finally meet the potential it has promised for so long, creating a tantalising future for the crowd of service and equipment providers offering their assistance.
Trendsetter Engineering, a provider of specialised subsea hardware and offshore service solutions from exploration drilling through to abandonment, has announced the recent completion of two deepwater well stimulation campaigns for major operators in the Gulf of Mexico.
The two campaigns resulted in the successful acid treatments of a combined six wells. The campaigns arrived on the heels of a contract agreement to deliver hydraulic intervention and technical services via the Subsea Tree Injection Manifold (STIM) for a Hydrate Remediation and Flowline Flush Project in the Gulf of Mexico.
The Trendsetter STIM offers a 15,000psi rated subsea safety system designed to provide hydraulic well access for both vertical and horizontal tree types. In addition to hydraulic well stimulation, the STIM unit has been used and is capable of supporting various other hydraulic intervention operations including hydrate remediation, bull heading of kill weight fluid and cement as well flowline flushing and testing operations for both pre and decommissioning.
Expro has secured a contract with a major operator for the first deployment of its unique single shear and seal high-debris 15K ball valve assembly.
The multi-functional single shear and seal mechanism will form part of a full subsea deepwater completion/intervention system being designed by Expro for a long-standing and valued customer for a deepwater subsea field at about 6,600 ft in the Gulf of Mexico.
The mechanism is designed to answer the customer’s requirement for a versatile, single-valve subsea solution rather than the conventional double-valve system while offering the reassurance of risk reduction through an additional safety barrier.
Graham Cheyne, Expro’s Vice President of Subsea Well Access, commented, “We are proud to offer our innovative shear and seal solution to meet the needs of this important customer in the Gulf of Mexico. Our cutting-edge technology propels the industry’s momentum towards increased automation, improving safety on the rig floor by minimising personnel and mitigating human error, while providing an additional safety barrier. It offers operators with flexibility for their operations in both in-riser and open water subsea applications.”
Expro’s high-debris single ball system, which delivers shear and post shear seal on a multitude of sizes of coiled tubing, slickline, and electrical cable, is a solution for both gas and liquid. Its versatility makes it suitable for deployment in both in-riser or open water environments.
It is NACE MR0175 compliant and qualified for sour hydrogen sulfide environments. Bi-directional sealing is available even after a pump-through. The mechanism has been qualified to API 17G standard for the performance and design of subsea well intervention equipment. Its ability to handle up to 15% debris is a significant improvement over alternative mechanisms used in this environment today.
Expro’s shear and seal valve is available in the ELSA-HP 15ksi enhanced landing string assembly.
