What are unconventional reservoirs?
An unconventional reservoir consists of an ultra tight source rock, trap and seal containing organic rich matter that has reached thermal maturity without migration.
What is the difference between conventional and unconventional reservoirs?
Because they are easier and less expensive to produce, conventional oil and gas were the first targets of industry activity. By contrast, unconventional resources are trapped in reservoirs with low permeability, meaning little to no ability for the oil or natural gas to flow through the rock and into a wellbore.
What is a conventional reservoir?
1. n. [Shale Gas, Geology] A reservoir in which buoyant forces keep hydrocarbons in place below a sealing caprock. Reservoir and fluid characteristics of conventional reservoirs typically permit oil or natural gas to flow readily into wellbores.
Is shale an unconventional reservoir?
Shale gas formations are “unconventional” reservoirs – i.e., reservoirs of low “permeability.” Permeability refers to the capacity of a porous, sediment, soil – or rock in this case – to transmit a fluid. This contrasts with a “conventional” gas reservoir produced from sands and carbonates (such as limestone).
What is the difference between conventional and non conventional oil?
Conventional oil is a category that includes crude oil – and natural gas and its condensates. Unconventional oil consists of a wider variety of liquid sources including oil sands, extra heavy oil, gas to liquids and other liquids. In general conventional oil is easier and cheaper to produce than unconventional oil.
What is unconventional resource?
1. n. [Geology, Shale Gas] An umbrella term for oil and natural gas that is produced by means that do not meet the criteria for conventional production.
Is shale a reservoir rock?
Shale is a common type of tight reservoir that is composed of extremely fine-grained, sedimentary rock and may contain oil or natural gas – referred to as “shale oil” or “shale gas”.
What are non-conventional resources?
Nonconventional energy sources (also called alternative energy sources) are any sources or substances that can be used to produce fuels, other than conventional fuels. These are sources that are continuously replenished by natural processes, including biomass, hydropower, nuclear power, solar energy, and tidal energy.
What is the meaning of non-conventional resources?
Renewable energy sources also called non-conventional energy, are sources that are continu- ously replenished by natural processes. For example, solar energy, wind energy, bio-energy – bio-fuels grown sustain ably), hydropower etc., are some of the examples of renewable energy.
