What is an unconventional oil reserve?
In the oil and gas industry, the term “unconventional oil” refers to crude oil that is obtained through methods other than traditional vertical well extraction. Examples of such methods include developing oil sands, directional drilling, and hydraulic fracturing (colloquially known as “fracking”), among others.
What is the definition of unconventional oil reserves quizlet?
unconventional oil reserves. recoverable oil that exists in rock, sand, or clay but whose extraction is economically and environmentally costly.
What is the difference between conventional and unconventional 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 are the types of unconventional oil?
The U.S. Department of Energy divides unconventional oil into four types: heavy oil, extra heavy oil, bitumen, and oil shale. Some analysts also include gas-to-liquids (GTL) processes for converting natural gas to oil and coal-to-liquids (CTL) processes for converting coal to oil in the unconventional oil category.
What is the difference between conventional and unconventional resources?
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.
Which is an example of an unconventional fossil fuel reserve quizlet?
Which is an example of an unconventional fossil fuel reserve? FEEDBACK: Tar sand is considered an unconventional reserve because its hydrocarbons cannot flow, making extraction of the hydrocarbons difficult.
Is dewatering conventional or unconventional?
Background information on various unconventional oil and gas (UOG) techniques, including hydraulic fracturing (“fracking”) and underground coal gasification. Techniques such as horizontal drilling, dewatering, and hydraulic fracturing can be used to access and retrieve the natural gas contained within the ground.
What are conventional reserves?
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.
What does conventional and unconventional mean?
: not conventional : not bound by or in accordance with convention : being out of the ordinary an unconventional outfit an unconventional thinker.
What is an example of an unconventional fossil fuel reserve?
Which is an example of an unconventional fossil fuel?
What are unconventional fossil fuels? Shale gas, tight gas and coalbed methane are examples of unconventional natural gas, but also oil could potentially be extracted from unconventional reservoirs such as shales using hydraulic fracturing techniques.
