In the Gulf of Mexico, there are more than 600 natural oil seeps that leak between one and five million barrels of oil per year, equivalent to roughly 80,000 to 200,000 tonnes. [40] When a petroleum seep forms underwater it may form a peculiar type of volcano known as an asphalt volcano .
An oil spill is the release of a liquid petroleum hydrocarbon into the environment, especially marine areas, due to human activity, and is a form of pollution. The term is usually applied to marine oil spills, where oil is released into the ocean or coastal waters , but spills may also occur on land.
The small hamlet of Drayton Valley grew rapidly after Pembina oil was discovered in 1954, and became Alberta's first model oil town. [46] This was the period when many wells were drilled; by 2017, there were approximately 400,000 in Alberta. [47] Canada's oil production in 1946 was only 21,000 barrels (3,300 m 3) of oil per day.

This is a reverse-chronological list of oil spills that have occurred throughout the world and spill(s) that are currently ongoing. Quantities are measured in tonnes of crude oil with one tonne roughly equal to 308 US gallons, 256 Imperial gallons, 7.33 barrels, or 1165 litres.
A detailed inventory of greenhouse gas emissions from upstream oil and gas activities in Canada for the year 2000 estimated that fugitive equipment leaks had a global warming potential equivalent to the release of 17 million metric tonnes of carbon dioxide, or 12 percent of all greenhouse gases emitted by the sector, [9] while another report put fugitive emissions at 5.2% of world greenhouse ...

The Canadian oil and gas industry produces "60 per cent of all industrial emissions in Canada" [5] and Alberta has the largest oil and gas industry in the country. [5] By September 2017, Alberta had already begun "implementing broad climate change policies" including a "sophisticated two-tier carbon pricing system" for consumers and major emitters.
