What is an unconventional oil source
What is "Unconventional" Oil and Gas? "Unconventional" oil and gas is not chemically different from "conventional" oil and gas. The distinction stems from their position underground or from the unusual nature of their reservoirs. These conditions require the use of new, often complex, extraction methods. Unconventional oil and gas refers to the oil and gas resources which cannot be explored, developed and produced by conventional processes just in using the natural pressure of the wells and pumping or compression operations. These unconventional crude oil and natural gas are trapped in the pores of sediments rocks called shale. Comments Oil shale is a sedimentary rock containing clays impregnated with a solid hydrocarbon known as kerogen that can be processed to produce a fuel oil similar to crude. Shale oil is an unconventional source of oil whereas crude oil is a conventional source. To obtain hydrocarbons from these hard-to-reach sources, a combination of horizontal drilling and hydraulic fracturing is done. Conventional and Unconventional Oil and Gas in The U.S. The main reason for developing advanced technologies to explore and extract hydrocarbons in the U.S. is the disparity between conventional and unconventional oil
Highly variable oil prices and increasing world demand for oil have led producers to look for alternative sources of transportation fuel. Two popular alternatives
23 Jul 2018 An unconventional reservoir consists of an ultra tight source rock, trap and seal File:Figure 1- Conventional and Unconventional Oil and Gas 1 Jan 2010 As with shale oil, shale gas systems are considered discrete, self-enclosed systems in which the source, seal and reservoir are one and the Innovation will also play a key role in maximizing what is extracted from these non-conventional oil and gas sources, while at the same time minimizing the costs Unconventional oil sources remained relatively untapped compared to conventional sources while conventional sources were plentiful. This is simply due to the technical requirements and costs Unconventional oil is petroleum produced or extracted using techniques other than the conventional method.Oil industries and governments across the globe are investing in unconventional oil sources due to the increasing scarcity of conventional oil reserves.Unconventional oil and gas have already made a dent in international energy linkages by reducing US energy import dependency. In general, unconventional oil is heavier and requires more processing and upgrading. Unconventional oil includes shale oil, oil sands and extra-heavy oil (natural bitumen deposits). In total, only about 3% of 2009's oil production came from unconventional oil sources.
Oil shale Some unconventional deposits of oil are found in microporous, impermeable source rock, known as oil shale, rather than in a standard porous: oil found in source rock that has not been buried deep enough for the organic matter to turn into oil. Oil shale is extracted using surface or underground mining then heated to a high temperature (450°C) to obtain the oil – picking up where nature left off.
Unconventional oil has not been formally defined, but can be said to consist of oil that has been extracted using techniques other than traditional oil wells. These currently include the extraction of oil from oil shales and sands, synthetic crude oils, coal-base or biomass-based liquid supplies and gas to liquid processes. Unconventional gas is natural gas obtained from sources of production that are, in a given era and location, considered to be new and different. Sources that are at times considered to be unconventional include the following: Coalbed methane [citation needed] Methane clathrate (gas hydrate) [citation needed] Shale gas [citation needed] The term refers to the renewable or, we can say, unlimited energy source. The best example is wind energy. As compared to traditional energy sources like water or coal, unconventional sources are pretty much new. Hence, the majority of the time, they are not considered as standard resources of energy. Moreover, renewable energy sources are much less harmful to the environment compared to the energy generated from fossil fuels. Unconventional oil and gas refers to the oil and gas resources which cannot be explored, developed and produced by conventional processes just in using the natural pressure of the wells and pumping or compression operations. These unconventional crude oil and natural gas are trapped in the pores of sediments rocks called shale. Unconventional Oilseeds and New Oil Sources: Chemistry and Analysis is presented in three parts, with each section dedicated to different types of oil sources. Part One deals with plants (vegetable, herbs, shrubs), such as Hibiscus, Mexican Poppy, Cucumber, Squashes, Sesame, etc. Part Two presents unconventional oils found in trees (like
Major Unconventional Sources Oil Sands. Oil sands, i.e., “tar sands” or “natural bitumen,” are a combination of sand (83%), bitumen (10%), water (4%), and clay (3%). 8 Bitumen is a semisolid, tar-like mixture of hydrocarbons. 9; Known oil sands deposits exist in 23 countries.
4 Apr 2012 Sources of unconventional oil and gas include: Shale gas, shale oil, tight sands, clathrates (gas hydrates), coal bed methane (CBM). Extraction Highly variable oil prices and increasing world demand for oil have led producers to look for alternative sources of transportation fuel. Two popular alternatives Oil and gas production from shale has been steadily growing. Now, after decades of remaining heavily dependent on foreign energy sources, the United States Unconventional oil and gas is extracted from non-traditional geologic sources. At Stanford, researchers are studying the geological, environmental and 24 Oct 2012 By 2020, IHS projects, it will bypass oil from conventional and deep-water sources combined, hitting 4.5 million barrels per day. Here's a chart that

In contrast to this, unconventional oil or gas resources are much more difficult to extract. Some of these resources are trapped in reservoirs with poor permeability and porosity, meaning that it is extremely difficult or impossible for oil or natural gas to flow through the pores and into a standard well.
