What are some of the alternative unconventional resources for oil and natural gas?



What are some of the alternative, unconventional resources for oil and natural gas? The main substitutes for oil and gas energy include nuclear power, solar power, ethanol, and wind power. Sources of this type of unconventional oil include oil sands, oil shale, shale oil.

What are some of the unconventional sources of oil and natural gas?

Unconventional natural gas (UG) comes primarily from three sources: shale gas found in low-permeability shale formations; tight gas found in low-permeability sandstone and carbonate reservoirs; and coalbed methane (CBM) found in coal seams.

What is an unconventional oil resource?

What is Unconventional Oil? Unconventional oil refers to oil reserves that cannot be feasibly accessed using conventional drilling techniques. These reserves – notably tight oil, oil shale, and bitumen – must be extracted using novel methods.

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 unconventional natural gas?

Unconventional gas refers to natural gas that requires advanced production methods. Main types include gas within tight pore spaces – shale gas and coal bed methane – and gas that is trapped in ice on the sea floor – gas hydrates.

What is conventional source of oil and gas?

Conventional petroleum resources are extracted using traditional methods of drilling down through the ‘cap’ rock and allowing petroleum to flow up the well. The resources that can be extracted from conventional petroleum reserves include crude oil, condensate and natural gas.

What is the difference between conventional and unconventional oil and gas?

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.

What are two types of unconventional oil?





Unconventional oil

  • Within the vast unconventional resources category, there are several different types of hydrocarbons, including very heavy oils, oil sands, oil shales, and tight oils. …
  • Very heavy crudes have become economical.

How much unconventional oil is there?

According to an international institution, the total unconventional oil resources in the world, including heavy oil, natural bitumen, and oil-shale oil, are approximately (2200–9300) × 108 t, which is 0.5–1.9 times that of its conventional counterpart.

What is unconventional oil reservoirs?

Production from unconventional petroleum reservoirs includes petroleum from shale, coal, tight-sand and oil-sand. These reservoirs contain enormous quantities of oil and natural gas but pose a technology challenge to both geoscientists and engineers to produce economically on a commercial scale.

What are unconventional energy tools *?

What is consider to be unconventional energy sources are wind, tidal, solar, nuclear, and geo-thermal. Occasionally, these sources are also refereed to as renewable energy. They are used all over the world. These sources are not the standard, because they are still relatively new compared to oil and gas.

Why is oil and gas unconventional?

Unconventional Resources are oil or gas-bearing units where the permeability and porosity are so low that the resource cannot be extracted economically through a vertical well bore and instead requires a horizontal well bore followed by multistage hydraulic fracturing to achieve economic production.



What are the traditional and unconventional forms of fossil fuels?

Fossil fuels include coal, natural gas, and liquid petroleum. Unconventional fossil fuels include nonliquid forms of petroleum, such as oil shale, shale oil, oil sands, tar sands, and heavy oils. Unconventional forms of natural gas include shale gas and coalbed methane.

What are the two forms of unconventional fossil fuels?

At the same time, attention is turning towards what are called ‘unconventional fossil fuels’. There are four: tar sands, oil shale, shale gas and deepwater oil.

What are the unconventional energy sources?

What is consider to be unconventional energy sources are wind, tidal, solar, nuclear, and geo-thermal. Occasionally, these sources are also refereed to as renewable energy. They are used all over the world. These sources are not the standard, because they are still relatively new compared to oil and gas.

What resources are unconventional?

Oil and natural gas trapped in less permeable rocks is referred to as an unconventional resource because it cannot be explored, developed and produced by conventional processes. Shale gas is natural gas trapped in shale rock.

What are the traditional and unconventional forms of fossil fuels?

Fossil fuels include coal, natural gas, and liquid petroleum. Unconventional fossil fuels include nonliquid forms of petroleum, such as oil shale, shale oil, oil sands, tar sands, and heavy oils. Unconventional forms of natural gas include shale gas and coalbed methane.
