Conventional oil is a category that includes crude oil - and natural gas and its condensates. Crude oil production in 2011 stood at approximately 70 million barrels per day. Unconventional oil consists of a wider variety of liquid sources including oil sands, extra heavy oil, gas to liquids and other liquids.
24 Feb 2019 Conventional oil or gas comes from formations that are "normal" or straightforward to extract product from. Extracting fossil fuels from these 28 Jun 2018 Over time, however, most of the conventional sources were already tapped and producing, drawing down the conventional oil reserves around 30 Sep 2015 Sediments like sandstone, however, are formed in layered deposits. Instead of a pool, oil in these layers is spread out in small amounts. To reach As conventional oil and gas reservoirs are depleted, unconventional gas and oil reservoirs will be developed in those basins. Conventional gas and oil resources Unconventional oil refers to oil reserves that cannot be feasibly accessed using conventional drilling techniques. These reserves - notably tight oil, oil shale, and 7 Sep 2012 Conventional and unconventional oil and gas come from the same Each reservoir will be measured in respect with it proven resources and
See Conventional oil and natural gas production. Note: What has qualified as " unconventional" at any particular time is a complex interactive function of resource
As conventional oil and gas reservoirs are depleted, unconventional gas and oil reservoirs will be developed in those basins. Conventional gas and oil resources Unconventional oil refers to oil reserves that cannot be feasibly accessed using conventional drilling techniques.

However, Purchase Unconventional Oil and Gas Resources Handbook - 1st Edition. Review of Lithofacies Classification in Conventional Formation Evaluation; 5.3. 7 Oct 2014 Unconventional Oil Exploration, Part 1: What Makes Oil Conventional and unconventional resources are also defined by how they are
Conventional resources and unconventional resources are two very different, separate sets of resources that can potentially be extracted. Both refer to some quantity of fossil fuels that could contribute to a reserve if they could be extracted economically.The distinction between a resource and reserve is explored with a diagram known as a McKelvey box .
Unconventional oil resources are typically more expensive to produce than conventional oil, often in the $40-$80/barrel range for production. However, the production of unconventional oil is increasing due to rising demand for fossil fuels and falling reserves of conventionals . According to the statistics of the USGS and DOE, the volume of global unconventional oil resources is 4495 × 10 8 t, including shale oil at 2770 × 10 8 t, bitumen at 2770 × 10 8 t, and heavy oil at 2770 × 10 8 t, which is equal to that of conventional petroleum resources. Conventional oil costs much less to produce than unconventional, so companies producing conventional oil have a much higher profit margin. Conventional oil is oil produced using standard drilling techniques. These large pools of oil simply need to be drilled into so the oil can be extracted. Unconventional Resources Conventional: High-permeability reservoirs that can be produced by traditional methods Unconventional Low permeability reservoirs Immature source rocks Production of adsorbed hydrocarbons Heavy oil that will not flow naturally Hydrocarbons in weird forms What are the Unconventional Resources? Shale Gas/ Shale oil Tight Gas Sands Oil Shale Coal-bed Methane
Conventional versus Unconventional Oil and Gas Conventional Resources are concentrations of oil or gas that occur in discrete accumulations or pools. Rock formations hosting these pools traditionally have high porosity and permeability and are found below impermeable rock formations. These impervious layers form barriers to hydrocarbon migration resulting in oil and gas being trapped below them.
