Depleted product stocks and a spate of unscheduled refinery outages lifted European and Asian refining margins to two-year highs, while US Mid-continent margins doubled in a matter of days following a refinery outage. Global oil supply can’t meet the current rate of global oil demand forever, necessitating new energy sources and usage practices. Even if technology allowed us to harvest every last drop of oil in the planet (thereby increasing scarcity), rising prices and climate impacts would necessitate widespread change long before we actually ran out of oil.

History of Oil Reserves in Venezuela
However, it also raises environmental concerns related to water usage, contamination, and seismic activity. Declining oil resources can lead to increased geopolitical tensions as countries compete for access to remaining reserves. It can also shift the balance of power, favoring countries with abundant oil resources or those that are leading the transition to alternative energy sources. This competition can manifest in various forms, including trade disputes, political alliances, and even armed conflict. The question of how much oil remains buried beneath our feet is perhaps one of the most critical questions facing humanity. This figure, however, obscures a far more nuanced reality involving economic viability, environmental concerns, and evolving geopolitical landscapes.
These sources require more complex and expensive extraction methods than conventional oil. They contribute significantly to global supply, particularly from countries like Canada (oil sands) and the United States (shale oil). Their contribution is expected to continue growing as conventional oil production declines.
It’s important to distinguish between different types of oil reserves and the impact of technological advancements on their accessibility. Oil is one of the most precious resources on Earth, powering economies and industries around the world. As we enter an era of heightened environmental awareness and climate change concerns, it’s more important than ever to understand how much of this valuable resource remains in our reserves. By the time the Panama Canal is as old to our descendants as the Great Pyramid is to us, virtually all the categories of energy resources we’d recognize from the twentieth century will have been exhausted several times over. This fact holds true even when I stack optimistic assumption on top of optimistic assumption down the whole logical chain. Each scenario imagines a flat rate of growth or contraction of oil consumption and lists a range of years by which we’ll have consumed 99% of the planet’s recoverable oil.
However, technological advancements and the discovery of new resources could significantly alter this timeline. In the sections above, we looked at the consumption of fossil fuels collectively. But it’s important to look at the role of coal, oil, and gas individually – their impacts are not equal. Coal, for example, typically produces more CO2 and local air pollution per unit of energy see our article on the relative safety and impacts of different energy sources. This article presents the long-run and recent perspectives on coal, oil, and gas – how much countries produce and consume, where our fossil fuel reserves are, and what role the fuels play in our energy and electricity systems.
How Much Oil Does the Earth Have Left?
When prices are high, companies are more willing to invest in expensive and risky projects, such as deep-water drilling and EOR. Conversely, when prices are low, production may be curtailed and exploration efforts reduced. Therefore, the amount of economically recoverable oil fluctuates with market conditions. Oftrb.com is a comprehensive energy portal, the main columns include crude oil prices, energy categories, EIA, OPEC, crude oil news, basic knowledge of crude oil, etc. While oil has undoubtedly played a critical role in powering modern society, its extraction and use come with significant environmental costs. Oil drilling and extraction can pollute soil, water, and air, leading to health risks for nearby communities.
- Companies like BP, ExxonMobil, and Shell all have dedicated teams performing these estimations.
- This represents gas production adjusted for trade (so, gas exports are subtracted and imports are added).
- OPEC (Organization of the Petroleum Exporting Countries) is a cartel of oil-producing nations that coordinate their oil production policies to influence global oil prices.
- China saw a significant jump from last year due to the de-risking of technically recoverable shale resources, with total reserves now estimated at 75 billion barrels.
- But the quick answer is that not too soon, as the goalpost has been constantly moving.
Petrochemical feedstocks remain the bedrock of global gains, but so far this year the sector has significantly underperformed expectations. In 4Q25, global oil consumption growth is expected to ease relative to 3Q25 while crude supply is on course to rebound further, adding to market balances that look increasingly askew. Global oil market balances are looking increasingly lopsided, as world oil supply is forging ahead while oil demand growth remains modest by historical standards.
Fossil fuel production is an important metric – it helps us understand where fossil fuels are being extracted. But we also care about where that energy is being consumed – that tells us what role fossil fuels are playing in the energy system of each country. Globally, fossil fuels account for a much smaller share of electricity production than the energy system as a whole. Looking at energy consumption at the country level is often a strong reflection of population size rather than actual fossil fuel consumption per person.
Resources encompass all potential oil deposits, including those that are not yet discovered or economically viable to extract. Reserves are a subset of resources that are both discovered and economically viable. Unconventional oil, such as oil sands, shale oil, and ultra-deepwater oil, represents a significant portion of the world’s remaining potential reserves.

Earlier data, pre-1965, is sourced from Vaclav Smil’s work on energy transitions; this has been combined with data published in BP’s Statistical Review of World Energy from 1965 onwards.1 A 1977 report issued by the Energy Information Administration concluded that the United States could only access 32 billion barrels of oil reserves and 207 trillion cubic feet of natural gas reserves. But from then to 2010, the country extracted 84 billion barrels of oil (2.6 times more than the initial estimate) and 610 trillion cubic feet of gas (2.9 times the initial reserve estimate). Today, the U.S. has increased the size of its reserves by a third since 2011 thanks to horizontal drilling and hydraulic fracking which enable access to oil and gas trapped in underground rock formations. So, the challenge in estimating a timescale for fossil fuel depletion lies in the fact that new resources are added fairly regularly. Therefore, we have to keep in mind that all of these estimates are based on R/P ratios and thereby only consider proven reserves, not probable or possible reserves of resources.
How do geopolitical factors affect oil prices and availability?
Discovery is likely based on interpretation of geological and geophysical data, but without direct well testing. These are often contingent on significant technological breakthroughs or drastic changes in oil prices. Therefore, when we discuss “how much petrol is left,” we are fundamentally referring to the amount of crude oil available, as that is the source material for petrol production. Although Venezuela has the most oil reserves in the world, most of its oil is offshore or far underground and is considered to be dense. As such, the cost of extracting the oil in Venezuela’s reserves using the technology currently available is too high to be profitable.
Factors Influencing Oil Reserve Estimates
It typically involves surface mining or in-situ techniques, such as steam-assisted gravity drainage (SAGD), which inject steam into the oil sands to reduce the viscosity of the bitumen and allow it to flow to the wellbore. Oil extraction and consumption have significant environmental consequences, including greenhouse gas emissions, air and water pollution, habitat destruction, and the potential for oil spills. The burning of fossil fuels is a major contributor to climate change, and oil spills can devastate marine ecosystems. This category encompasses oil reserves that are difficult and costly to extract using traditional methods. While these reserves are vast, their extraction carries significant environmental and economic hurdles. This category harbors the highest level of uncertainty, with less than a 10% probability of economic extraction under current conditions.
How the Accessibility of Oil Reserves Impacts Profitability
This category contains metrics such as land area, natural resources, and topography, along with groupings of states by their location in the US. Key technologies being developed to improve oil extraction include enhanced oil recovery (EOR) techniques, advanced drilling technologies, and improved seismic imaging. These technologies aim to increase the amount of oil that can be recovered from existing fields and to locate new reserves. Geopolitical instability, conflicts, and political decisions can significantly affect oil prices and availability. Disruptions to supply chains, sanctions, and trade agreements can all influence the global oil market.
FAQ 12: What steps can individuals and governments take to reduce oil consumption?
- The price of oil is a crucial factor determining the economic viability of oil production.
- Conversely, rapid industrialization in developing nations and continued reliance on oil for transportation could accelerate depletion.
- The world’s remaining oil reserves are insufficient to support oil demand if there is no transition to electric vehicles.
- However, everyone seems to agree that we still have at least many decades before these resources run out even with today’s voracious consumption of energy.
- Furthermore, technologies like hydraulic fracturing (fracking) have opened up access to previously inaccessible shale oil and gas resources, dramatically altering the global energy landscape.
Whether we have already passed peak oil is still debated, and future production trends will depend on factors like demand, technological innovation, and geopolitical stability. The specific consequences of running out of crude oil will depend on how much natural gas and coal remain. Yes, a range of alternative energy sources has the potential to replace oil in the future. These include renewable energy sources such as solar, wind, hydro, and geothermal power, as well as nuclear power. Electric vehicles powered by batteries or hydrogen fuel cells offer a potential replacement for gasoline-powered vehicles.
Oil production is an important indicator to follow – it helps us understand where it’s being extracted, who the main oil producers are, and how this relates to oil reserves. But we also care about where that oil is being consumed – that tells us how much oil is left in the world what role it’s playing in the energy system of each country. This interactive map shows the share of electricity that comes from fossil fuels (coal, oil, and gas summed together) across the world.
