Schematic unconventional reservoir classification expressed as fluid energy vs flow potential based on initials without stimulation. Unconventional (oil and gas) reservoirs, or unconventional resources (resource plays) are accumulations where oil and gas phases are tightly bound to the rock fabric by strong capillary forces, requiring specialized measures for evaluation and extraction.
Reservoirs are broadly classified as conventional and unconventional reservoirs. In conventional reservoirs, the naturally occurring hydrocarbons, such as crude oil or natural gas, are trapped by overlying rock formations with lower permeability, while in unconventional reservoirs the rocks have high porosity and low permeability, which keeps ...
Reservoir simulation is an area of reservoir engineering in which computer models are used to predict the flow of fluids (typically, oil, water, and gas) through porous media. The amount of oil & gas recoverable from a conventional reservoir is assessed by accurately characterising the static recoverable volumes and history matching that to ...
(The data below does not seem to include shale oil and other unconventional sources of oil such as tar sands. For instance, North America has over 3 trillion barrels of shale oil reserves, [ citation needed ] and the majority of oil produced in the US is from shale, leading to the paradoxical data below that the US will finish all its oil at ...
Tight gas reservoirs historically were generally defined as having less than 0.1 millidarcy (mD) matrix permeability and less than ten percent matrix porosity. [ 2 ] [ 3 ] Although shales have low permeability and low effective porosity, shale gas is usually considered separate from tight gas, which is contained most commonly in sandstone, but ...
In Alaska, our EarthStar ultra-deep resistivity tool and reservoir mapping service deliver unmatched performance and unique insights for customers, drilling extended reach wells on the North Slope.
US shale gas basins, 2011. Shale gas in the United States is an available source of unconventional natural gas.Led by new applications of hydraulic fracturing technology and horizontal drilling, development of new sources of shale gas has offset declines in production from conventional gas reservoirs, and has led to major increases in reserves of U.S. natural gas.
(The Center Square) – Ohio plans to spend $2 million of taxpayer money to encourage more people to work in the children services industry. Gov. Mike DeWine recently announced the Ohio Child ...
