The American shale oil and gas boom that began at the beginning of this century had enormous geopolitical implications. Without it, the United States would have become increasingly dependent on imports to meet its energy needs and prices would undoubtedly have been higher. In fact, in the years leading up to the shale revolution, natural gas prices skyrocketed and oil prices surpassed $100 a barrel.
But the resulting increase in oil and natural gas production in the United States would later make the United States the largest oil and gas producer in the world. This weakened OPEC’s control over world oil markets, and the United States would become the world’s largest exporter of liquefied natural gas.
But shale oil and gas resources are not limited to the U.S. The map below from the Energy Information Administration shows how widely dispersed these resources are around the world.

As the US shale revolution matures and its growth shows signs of stalling, energy markets are increasingly assessing which countries could follow the US lead. Several countries are positioning themselves for a shale boom, with profound implications for energy security, geopolitical leverage and investment opportunities.
Let’s consider Vaca Muerta, a formation that until recently was more promising than productive. Located in the Neuquén Basin of northern Patagonia, Argentina’s unconventional exploitation is now showing commercial traction. According to the EIA, the technically recoverable resource in the basin is approximately 16 billion barrels of oil and 308 trillion cubic feet of gas. In 2024, the basin’s oil production increased by 27% and gas production by 23% year over year.
Big players like YPF, Chevron and Shell are deeply committed. Chevron, for example, has publicly stated that Vaca Muerta is one of the world’s most important unconventional oil reserves and has committed to increasing its production to 30,000 barrels per day by the end of 2025.
Of course, Argentina faces classic shale obstacles: regulatory and fiscal uncertainty, high well costs, water logistics and infrastructure bottlenecks. But the upward momentum is real. In short, Vaca Muerta is the first basin outside the United States to show credible scale and depth of investment.
Then there is China, which has the world’s largest technically recoverable shale gas reserves, centered in the Sichuan Basin. While development has been slow (due to complex geology, difficult access and water limitations), China is implementing digital drilling, horizontal wells and hydraulic stimulations to accelerate progress. If successful, China’s shale gas push could reshape the region’s LNG flows and reduce dependence on coal.
While less flashy than Argentina’s oil surge, China’s potential lies in scale and transformative impact: a domestic shift that would ripple through global energy trade. Success there could disrupt global LNG markets, reduce Asian demand for coal and strengthen China’s energy independence.
The third important narrative is the unconventional turn of the Kingdom of Saudi Arabia and Saudi Aramco. The Jafurah basin has been described as “the jewel of our unconventional gas program”, with approximately 229 trillion cubic feet of raw gas and 75 billion barrels of condensate in place. First production is planned for 2025, with a sales target of 2 billion cubic feet per day by 2030.
Why does this matter? Because Saudi Arabia is moving from oil-fueled domestic energy to gas-fueled industrial capacity, freeing up crude for export and reducing the carbon intensity of its own economy. From an investors’ perspective, the project indicates that shale (in this case, gas-rich) is becoming strategic infrastructure, not just an exploration hype.
Beyond those three, several other countries deserve attention:
Russia has immense shale oil and gas potential (by some estimates, it ranks second in shale oil after the United States), but its development remains limited. With abundant and lower-cost conventional reserves, Moscow has little economic motivation to invest heavily in shale technologies, especially under Western sanctions that restrict access to advanced drilling equipment.
Canada, particularly Alberta and British Columbia, continues to invest in unconventional gas and liquids, although at a slower pace of growth.
Australia has geological promise (Cooper and Canning basins) but remains bogged down by environmental and regulatory hurdles.
Mexico has enormous potential, but faces a labyrinth of regulatory and infrastructure challenges.
Colombia is moving forward with pilot projects in the Magdalena Valley, with state oil company Ecopetrol exploring shale oil opportunities despite social and legal obstacles.
India has begun assessing shale prospects in the Cambay and Krishna-Godavari basins, although high population density and complex land rules present significant challenges.
The United Arab Emirates is investing in unconventional gas fields in the Al Dhafra region as part of its goal of achieving gas self-sufficiency by 2030.
South Africa continues to study the Karoo Basin’s vast shale gas potential, but environmental concerns and water scarcity remain major barriers.
The UK has rich shale gas resources in the Bowland Basin, but strong public opposition and a government moratorium have frozen activity.
While the United States remains the benchmark for shale efficiency and scale, these offshore fields offer differentiated opportunities. As other countries develop their shale resources, be on the lookout for:
Infrastructure development: pipelines, export terminals, number of platforms and logistics.
Changes in internal policies: regulatory stability, tax regime, access to water and environmental licenses.
State-backed partnerships: Many of these works are not entirely private sector. National oil companies, sovereign wealth funds and strategic infrastructure arms are key players.
Although the story of shale in the United States is not over, it is about to enter a new phase. But the next wave may not come from tight oil in Texas. Instead, it may arise in Argentina, China and Saudi Arabia. For investors and energy strategists alike, unconventional global bets offer a different set of risks and potentially outsized rewards.
The Permian remains the center of the shale boom for now. But the frontier is changing, the players are changing, and the global scale of demand for unconventional oil and gas is only growing.
