Satish Rao, Managing Director at Clareo, attended the Offshore Technology Conference (OTC) in Houston, May 2026.
The Offshore Technology Conference draws the upstream oil and gas sector together each year. The upstream oil and gas sector and the critical minerals supply chain share more structural ground than their separate conference calendars suggest. Three observations from OTC 2026 make that case.
Offshore development as nation-building
Guyana’s President, His Excellency Irfaan Ali, opened OTC 2026 with an argument grounded in recent history. Guyana’s transformation from an agriculture-dependent economy to the world’s fastest-growing economy was triggered by ExxonMobil’s offshore oil discoveries in 2015. GDP grew 62.3% in 2022, sustaining double-digit growth since 2020, with GDP per capita rising from $6,950 in 2020 to over $20,000 in 2023. Guyana is directing that windfall into hydropower, wind, energy storage, and smart grid infrastructure. Regional energy interconnection with Suriname, French Guiana, and Brazil is also underway. President Ali presented Guyana as a reference point for other resource-holding nations considering how to translate a major discovery into durable economic change.
President Ali’s broader argument carried weight beyond Guyana. Energy demand already outpaces supply today, and the gap is expected to widen. The world needs more energy, and producing sufficient energy at an affordable cost is a structural challenge. Fossil fuels hold approximately an 80% share of global primary energy supply – a concrete measure of current demand, rather than a contradiction of the energy expansion agenda,
Energy and climate security are both legitimate obligations, and President Ali was of the opinion that this is not a contraction, but a reflection of the current energy landscape. There is also an inherent structural capital challenge in that a shift from a fuel-intensive to a mineral-intensive energy system requires capital for both hydrocarbon development and critical minerals, and this impacts the global south. He also urged developers not to swap one environmental crisis for another, as critical minerals mining comes with its own set of challenges. Technology innovation and R&D investment could provide the pathway to responsible development.
The long-term supply gap
Neil Kavanagh, former Chief Scientist and Global Innovation Officer at Woodside Energy, engaged Rob Cordray, Managing Director of Rystad Energy Americas, in an executive dialogue on the role offshore could play as a critical anchor of future supply, and the strategic choices that will determine whether the global system remains resilient or becomes increasingly constrained in the decades ahead.
The near-term context is already instructive. The global liquids market shifted sharply in 2026, from an initial 3 million barrel-per-day projected surplus to a supply shock driven by geopolitical disruption in the Middle East. With the Strait of Hormuz affected, large volumes from Gulf producing nations are effectively stranded, creating a disruption that cannot be meaningfully offset in the near term. Production growth from the US, Brazil, and Guyana is cushioning the impact, but replaces only a fraction of disrupted volumes.
Even if the current disruption proves temporary, Rystad’s longer-term analysis is the more significant contribution. Without new drilling and completions, total global liquid production falls from around 100 million barrels per day today to under 20 million barrels per day by 2050. Substantial new discoveries are required to meet demand under any plausible future scenario.
Innovation as an enabler for future supply
The technology agenda at OTC 2026 reflected a sector investing simultaneously in performance improvement of existing operations and the pursuit of new resources. Leaders from ExxonMobil, Baker Hughes, and SLB each pointed toward AI and autonomous operations as the primary mechanism for compressing development timelines and unlocking previously inaccessible resources.
John Ardill, Vice President and Head of Global Exploration at ExxonMobil, described AI’s role in subsurface interpretation as an enabler capable of materially increasing recoverable volumes through deeper understanding of rocks and fluids. Baker Hughes showcased autonomous well construction. Fugro presented its GeoAI framework for geotechnical modelling. Advanced robotics, autonomous drones, and remotely operated vehicles are now deployed for structural inspections of hulls, masts, and pipelines, reducing human exposure in high-risk environments.
Subsea and drilling innovation featured prominently, with longer tiebacks to existing infrastructure lowering capital expenditure and accelerating production timelines across the Gulf of America, Guyana, and other deepwater regions. SLB received a conference award for enhancing drilling accuracy and well control in demanding environments. Bosch Rexroth presented next-generation subsea actuators for precise electrical control in subsea processing.
Integration of offshore operations with lower-carbon energy sources drew significant attention — systems combining floating wind and solar with subsea substations and storage, alongside carbon storage in depleted subsea fields. Digital twin technology is in active deployment for FPSO and subsea equipment management, with graphene-based self-healing coatings extending asset longevity in deep-water environments.
Implications for mining: three strategic concerns
The conference revealed three cross-industry parallels of significance to both mining companies and their downstream partners:
AI and the exploration timeline gap
S&P Global data shows copper mines average 16–17 years from discovery to production, with 12.3 years consumed by exploration and feasibility studies alone. Oil and gas exploration success rates have historically run at 30–50%; grassroots mining exploration can sit at one in hundreds or thousands of attempts. The gap reflects differences in how much both industries invest in understanding the ground before drilling. The AI-enabled subsurface interpretation work on display at OTC — and ExxonMobil’s argument that it can radically compress development timelines and unlock previously inaccessible resources — maps directly onto mining’s most persistent structural challenge. The technology pathway is visible; adoption pace is the variable.
The fuel-to-minerals transition as a supply constraint
President Ali named the structural shift explicitly: the global energy system is moving from fuel-intensive to mineral-intensive. The capital challenges he described for hydrocarbon development in the global south apply in equal measure to critical minerals. Rystad’s production cliff scenario has a direct parallel in the critical minerals supply picture, where a projected deficit between 2035 and 2050 is already visible in long-lead development timelines. Downstream industries — utilities, auto OEMs, battery manufacturers — are planning investment cycles that do not yet reflect the pace at which mining capacity needs to be committed today. The gap between mining’s development timelines and downstream planning horizons is itself a supply constraint, not just a geological one.
Manufacturing mindset and deployment speed
ExxonMobil’s Guyana development — discovery to first production in under five years using modular FPSO technology — remains the benchmark for what deployment speed looks like when a sector commits to a manufacturing approach. That mindset prioritises starting small, moving fast, and optimising continuously. The autonomous operations, digital twin investment, and modular system design at OTC 2026 reflect the same philosophy applied at scale. Mining’s 16–17 year average timeline is not purely geological; planning approaches and technology choices contribute substantially. The offshore sector’s active investment in compressing those timelines, rather than accepting them as fixed, is the most transferable lesson from Houston.
OTC 2026 reflected an oil and gas sector that has broadened its investment thesis. Alongside the search for new resources, the dominant focus has shifted to improving what is already producing. The cross-industry lesson for critical minerals development is that the same ambition is now a competitive requirement.
