Tight oil (also sometimes referred to as shale oil) is a petroleum play that consists of light crude oil contained in petroleum-bearing formations of low permeability, often shale or tight sandstone. Economic production from tight oil formations requires the same hydraulic fracturing and often uses the same horizontal well technology used in the production of shale gas.[1]

Although often referred to as shale oil, shale oil is more conventionally known as oil manufactured from oil shale by heating kerogen-rich rock.[2]

Tight oil formations include the Bakken formation, the Niobrara Formation, Barnett Shale, and the Eagle Ford Shale in the United States, R'Mah Formation in Syria, Sargelu Formation in the northern Persian Gulf region, Athel Formation in Oman, Bazhenov Formation and Achimov Formation of West Siberia in Russia, in Coober Peby in Australia, and Chicontepec Formation in Mexico.[1]
