Not all drilling is straight down, when they say depth it means how far they had to drill, sometimes this means covering huge horizontal distances too.
Geologists are the masters of locating oil. Often called oil exploration, geologists will look for an area that ticks all the boxes of finding an oil trap aka striking black gold. Oil is often found in the vast underground reservoirs where ancient seas were once located. This can either be beneath land or out in the ocean below the seabed. During the earlier years of oil mining, the geologists would study the soil, surface rock, and other surface features to determine if oil may be lying below.
The most common way used today is to generate shock waves that pass through the rock layers and reflect back to the surface where they can be interpreted for signs of oil traps. This is done with seismic source devices such as a compressed-air gun, a thumper truck, or explosives.
They then mark the location using GPS coordinates on land or by marker buoys on water. According to the most recent data from the IEA , an average of million barrels of oil were produced per day worldwide in That includes 32 million barrels a day of crude oil only, and 68 million barrels of crude oil, condensates, NGLs and oil from non-conventional sources.
The top five oil producing countries in to date are:. With production still on the rise as it has been for decades, experts are trying to calculate when, if ever, oil will run out.
However BP have made an estimate. And the year they give for the end of oil production if things remain the exact same as they are today - Yep, only another 48 years. That means without finding more reservoirs, reducing our consumption, or developing new technology, oil production could cease in Every previous doom-date prediction made has always been pushed back.
As Charles Darwin stated, to survive we must be able to adapt to change. We depend on oil for so much more than you might even realise.
Oil is present in almost every single part of our lives from the transport and production of food, clothing, materials, pharmaceuticals, and the plastics used to make a whole plethora of products. The impact of how drastic this change may be will depend heavily on the rate of decline and the development and adoption of oil alternatives.
In terms of the rate of decline, that will always be a hard one to measure. However, there is a possibility that oil prices will rise higher due to more complicated and expensive practices being required to source and extract along with the increase in supply and demand. Speaking of supply and demand, that has consistently been rising for the last decade and even with all the environmental concern, it is yet to slow down with a growth forecast of 1.
It is more likely then, that consumers will begin to look for more cost-effective alternatives if prices rise. Or, more efficient ways to produce and refine. It will more likely be a matter of our hand being forced than a global choice to change our ways as oil is just so essential to everyday life as we know it. But it is clear that we either need to research alternative resources. The United States' latest reminder of its petroleum dependency occurred when hurricanes Katrina and Rita struck the Gulf of Mexico, where the majority of the country's oil platforms and refineries are located.
Many of the structures suffered only glancing blows and were operating again soon afterwards. The idea that petroleum is formed from dead organic matter is known as the "biogenic theory" of petroleum formation and was first proposed by a Russian scientist almost years ago. In the 's, however, a few Russian scientists began questioning this traditional view and proposed instead that petroleum could form naturally deep inside the Earth.
This so-called "abiogenic" petroleum might seep upward through cracks formed by asteroid impacts to form underground pools, according to one hypothesis. Some geologists have suggested probing ancient impact craters in the search for oil. Abiogenic sources of oil have been found, but never in commercially profitable amounts.
The controversy isn't over whether naturally forming oil reserves exist, said Larry Nation of the American Association of Petroleum Geologists. It's over how much they contribute to Earth's overall reserves and how much time and effort geologists should devote to seeking them out.
