Petrostate

A petrostate or oil state is a country whose economy is heavily dependent on the extraction and export of oil or natural gas. The presence alone of large oil and gas industries does not define a petrostate: major oil producers that also have diversified economies are not classified as petrostates due to their ability to generate income from various industries and sectors beyond the oil industry. Petrostates also have highly concentrated political and economic power, resting in the hands of an elite, as well as unaccountable political institutions which are susceptible to corruption.
