Relationship between oil and gas reservoirs and shale oil and gas reservoirs

They are two different forms of oil and gas resources storage.

Oil and gas reservoir is a traditional form of oil and gas storage, which mainly exists in the deep underground. Oil and natural gas are obtained by drilling and exploiting oil and gas fields. Shale oil and gas reservoir is a new type of oil and gas resource reservoir discovered in recent years, which mainly occurs in shale formation. Natural gas and oil are obtained by fracturing shale gas.
