Latin America’s oil and gas industry closed 2025 as a study in contrasts: rapid deepwater expansion and shale-driven gas growth on one hand, and persistent political, regulatory, and infrastructure challenges on the other. This dynamic landscape is setting the stage for a pivotal 2026, where investment decisions, policy clarity, and global energy market shifts will determine whether the region solidifies its position as a key energy supplier or faces renewed volatility. The convergence of major offshore discoveries and unconventional resource development is reshaping not only regional economies but also the global energy map, with Latin America poised to play an increasingly influential role in both oil and liquefied natural gas (LNG) markets.

The 2025 Deepwater Surge: Brazil Leads, Guyana Soars

The standout story of 2025 was the acceleration of deepwater and ultra-deepwater projects, primarily driven by Brazil and Guyana. Brazil’s state-controlled Petrobras maintained an aggressive investment schedule in its prolific pre-salt basins, with production from fields like Búzios and Mero reaching new heights. According to industry reports and data from Brazil’s National Agency of Petroleum, Natural Gas and Biofuels (ANP), the country’s oil production averaged over 3.6 million barrels per day (bpd) in 2025, a significant portion of which came from these complex offshore reservoirs. The technological expertise required for these projects has turned Brazil into a global hub for deepwater innovation, attracting service companies and fostering a sophisticated local supply chain.

Meanwhile, Guyana continued its meteoric rise. ExxonMobil’s Stabroek Block, operated in consortium with Hess and CNOOC, saw multiple additional sanctionings in 2025, bringing the total number of approved projects in the block to over half a dozen. Production from the Liza, Payara, and Yellowtail developments pushed Guyana’s output well past 1.2 million bpd by year’s end, transforming the small nation into a top-tier oil producer virtually overnight. The rapid pace of development, however, has sparked intense discussions about fiscal management, local content, and environmental stewardship, debates that are closely watched by investors across the region.

The Shale Gas Revolution: Argentina’s Vaca Muerta Powers Growth

Parallel to the offshore oil boom, 2025 witnessed the consolidation of Latin America’s shale gas revolution, centered on Argentina’s massive Vaca Muerta formation. Often described as one of the world’s largest shale reserves, Vaca Muerta saw record-breaking production levels for both natural gas and shale oil. Data from Argentina’s Secretariat of Energy indicates that natural gas production from the Neuquén Basin, home to Vaca Muerta, increased by over 15% year-on-year in 2025, helping the country achieve seasonal energy self-sufficiency and begin planning for significant export capacity.

The growth was fueled by continued investments from national company YPF, alongside international players like Shell, TotalEnergies, and Chevron. A critical development in 2025 was the advancement of key infrastructure projects, most notably the Nestor Kirchner Gas Pipeline (formerly the Néstor Kirchner pipeline), which enhanced the capacity to transport gas from the remote basin to population centers and industrial hubs. This infrastructure unlock is crucial for the next phase: transforming domestic supply into a reliable export commodity, primarily through LNG.

The 2026 Watchlist: Key Factors Shaping the Future

As the industry looks to 2026, several critical themes will define its trajectory. These factors represent both opportunities for sustained growth and potential risks that could dampen the bullish outlook.

1. Political and Regulatory Landscape

Elections and policy shifts across the region will be paramount. In Mexico, the outcome of the 2024 general election and the subsequent energy policy direction of the new administration will significantly impact private investment, particularly in deepwater and shale. Brazil, despite its technical successes, continues to grapple with debates over Petrobras’s strategic focus and the role of private capital in the pre-salt. In Argentina, maintaining a stable and attractive framework for shale investment will be essential to secure the billions needed for LNG export terminals. Political risk remains the single largest overhang for long-term capital allocation in the sector.

2. The Race for LNG Export Capacity

2026 is poised to be a decisive year for Latin America’s LNG ambitions. The region is in a global race to build liquefaction capacity to meet rising demand, particularly in Europe and Asia. Several projects are vying for final investment decisions (FID):

  • Argentina: The most advanced plans involve floating LNG (FLNG) units and potentially larger onshore plants near Vaca Muerta. Projects like Exmar’s Tango FLNG and proposals from players like Shell and YPF are critical to monetizing gas reserves.
  • Brazil: While primarily an oil story, associated gas from pre-salt fields presents an LNG opportunity. Projects to capture and liquefy this gas are under study but face economic and logistical hurdles.
  • Other Players: Trinidad and Tobago seeks to rejuvenate its LNG industry with new gas supplies, while Peru aims to optimize its existing LNG plant.

The ability of these projects to secure long-term sales contracts, navigate environmental permitting, and finalize financing will determine if Latin America becomes a meaningful LNG exporter by the end of the decade.

3. Infrastructure and Supply Chain Constraints

The breakneck speed of development, especially in Guyana and Brazil’s offshore sector, is testing regional infrastructure and supply chains. Port capacity, offshore support vessel availability, and skilled labor are in high demand. In Argentina, building the pipeline network, storage, and LNG export facilities requires massive coordinated investment. Bottlenecks in any of these areas could delay projects and increase costs, eroding the competitive advantage of Latin American resources.

4. Environmental, Social, and Governance (ESG) Pressures

Global capital is increasingly allocated with ESG criteria in mind. For Latin America’s oil and gas sector, this presents a dual challenge. Offshore projects must demonstrate world-class safety and environmental standards, particularly in sensitive marine ecosystems. Shale development, through hydraulic fracturing, faces scrutiny over water usage and seismic activity. Furthermore, the social license to operate is crucial; communities in producing regions demand tangible benefits, job creation, and environmental protection. Companies that fail to lead on ESG metrics may find it difficult to attract partners and financing.

5. Global Market Dynamics and Competition

The region’s fortunes are inextricably linked to global oil and gas prices. A sustained period of lower prices could make some complex deepwater and shale projects less economical. Furthermore, Latin American producers are not alone; they compete for market share and investment with shale producers in the United States, deepwater projects in West Africa, and traditional suppliers in the Middle East. The region’s cost of supply, fiscal terms, and geopolitical stability will be constantly benchmarked against these global alternatives.

Regional Highlights Beyond the Giants

While Brazil, Guyana, and Argentina dominate headlines, other countries are navigating their own energy paths:

  • Colombia: Focused on exploring its offshore Caribbean potential while managing the decline of its traditional onshore basins. Licensing rounds in 2025 aimed to attract explorers to its deepwater frontier.
  • Mexico: Pemex’s heavy focus on shallow-water and onshore fields continues, but the country’s deepwater potential, opened by the 2013-14 energy reform, awaits clearer signals from the next government to attract major international investment.
  • Suriname: Hopes to follow Guyana’s success with discoveries in Block 58 (operated by TotalEnergies and APA Corporation). A final investment decision on the first major development is eagerly anticipated in 2026.
  • Bolivia: Faces the challenge of declining natural gas reserves and production, which threatens its long-standing export contracts with Brazil and Argentina.

Conclusion: A Region at an Energy Crossroads

Latin America enters 2026 with unprecedented hydrocarbon potential. The dual engines of deepwater oil and shale gas have positioned it for a new era of energy prominence. However, realizing this potential is not guaranteed. The “watchlist” for 2026 is dominated by man-made factors: political will, regulatory clarity, investment frameworks, and the ability to execute complex infrastructure projects. The industry must also successfully navigate the global energy transition, balancing the development of fossil resources with increasing societal and investor expectations for lower carbon operations and a clear path toward future energy systems.

The decisions made by governments and boardrooms in the coming year will either cement Latin America’s status as a growth engine for global oil and gas supply or expose the fragility of its boom under the weight of its own challenges. The contrast between geological fortune and governance will remain the defining theme of the region’s energy story.
