Geologists are often asked: How much oil and gas is left in the world

چکیده
The terms petroleum, crude oil, natural gas and natural gas liquids each have precise scientific definitions. But appending the word resource to any of them creates a term that crosses the boundary between science and social science and includes economics. Many geologists begin to feel uncomfortable in this area between science and social science. Webster’s Dictionary defines a resource as “a natural source of wealth or revenue.” A fossil fuel resource is one that can be profitably extracted. Compared to scientific terms, social science terms are fluid. What is profitable or societally acceptable one day may not be the next and vice versa. We must ask: How much profit is necessary extraction? What time frame are we considering?

Using game theory approach to interpret stable policies for Iran’s oil and gas common resources conflicts with Iraq and Qatar
Oil and gas as the non-renewable resources are considered very valuable for the countries with petroleum economics. These resources are not only diffused equally around the world, but also they are common in some places which their neighbors often come into conflicts. Consequently, it is vital for those countries to manage their resource utilization. Lately, game theory was applied in conflict ...
متن کاملDetermination of Time of Oil Cracking into Gas in Weiyuan Paleo-Oil Pool in Sichuan Basin, South China
Weiyuan gas field, located in the Sichuan basin of south China, is a large marine gas field with the oldest reservoir (the Sinian sequences) in south China. The hydrocarbon origin of the gas field has long been debated by petroleum geologists. Recently, it was recognized that a paleo-oil pool maybe the significant contributor to the gas field. Consequently, when the paleo-oil pool had been crac...

Background: Iran is located in the seventh rank in terms of CO2 emissions resulting from the fuel combustion in the world. Gas compressor booster stations, due to the several sources of contaminants, are causing the release of large amounts of CO2 and CH4, which will cause climate change therefore, estimating the emissions of the gases from oil and gas, different processing units are necessary....
متن کاملThe effect of smart water and silica nanoparticles injection on wettability of limestone
Today, by using half of the oil reserves of the world, natural production of oil has decreased drastically. Gas and water injection for maintaining reservoir pressure is not responsive for oil production.At first, we dispersed silica nanoparticles in low salinity and after two weeks, there was no change in its stability. Then we mixed the nanoparticles in low salinity. After a while, we found o...
