Indicated additional reserves typically refer to quantities of crude oil judged to be recoverable by enhanced recovery techniques, but where the economic recoverability of the reserves has not been established with sufficient conclusiveness for them to be included under proved reserves (Considine, 1977~. The term inferred reserves, also referred to as probable resources, is used to denote that part of the identified economic resource base that will be added to proved reserves through extensions, revisions, and new pay zones.

Eight countries (Saudi Arabia, Iraq, Kuwait, United Arab Emirates, Iran, all in the Middle East, along with the USSR, Venezuela, and Mexico) account for around 80 percent of the reserves, while the United States accounts for about 6 percent.

As cited by EIA, total resources include inferred reserves and undiscovered resources and are represented with a probability range of 95 to 5 percent.

In the United States, tar sand deposits are found in a number of states but the main deposit of about 12 billion bbl is found in Utah with speculative resources in that state amounting to about another 20 billion bbl (IOCC, 1984~. The resource in Alaska of 10 billion bbl is judged to be speculative.

Oil shale is sedimentary rock containing solid organic matter that when heated to around 500°C yields hydrocarbons and other solid products. Although oil shales are found in many places throughout the world, nearly 60 percent of the world's potentially recoverable resources are concentrated in the United States.
