Describe the distinction between conventional and unconventional oil and gas, and give examples of the unconventional varieties
What will be an ideal response?
Conventional oil and gas are found in large pools that can be extracted using traditional drilling and pumping. Unconventional oil and gas, including tar sands, oil shale, and shale gas, require far more effort and energy to extract and are thus less profitable sources of energy. Tar sands are a mixture of heavy oils and sand grains, with the oil and sand needing to be separated. Oil shale contains solid rather than liquid hydrocarbons and requires heating in order to release the oil. Shale gas, found in small cracks in seams of shale, needs to be hydrofractured (fracked) using high-pressure fluids in order to be released and extracted.
