Four tables are given presenting estimates for the remaining recoverable US fossil fuel resources. Table 1 summarizes the estimates for natural gas made over the past several years. Agencies making the estimates are indicated. Table 2 summarizes recent crude oil estimates. Remaining recoverable resources as of year-end 1978 are given ...

Laboratory studies performed on unconsolidated sandpacks showed that soluble oil flooding solutions are sensitive to divalent cations in interstitial water. Small amounts (1 to 2 percent) of clay, gypsum, or limestone were added to a sandpack and the packs were waterflooded to residual oil saturation, soluble-oil flooded, and ...

In the Central Overthrust belt fairway, there are 18 known productive formations ranging from Cambrian to Cretaceous in age. Four units - the Ordovician Big Horn formation, Mississippian Mission Canyon formation, Jurassic Nugget formation, and Jurassic Twin Creek Formation - account for 99% of a reported 1.4 billion bbl of oil estimated recoverable ...

Methane hydrates are methane bearing, ice-like materials that occur in abundance in permafrost areas such as on the North Slope of Alaska and Canada and as well as in offshore continental margin environments throughout the world including the Gulf of Mexico and the East and West Coasts of the United States. Methane hydrate accumulations in the United States are currently ...

Recovery of oil from bituminous sands in Northern Alberta is discussed. It is noted that about one tenth of the recoverable reserve, primarily that of the Athabasca deposit surrounding the town of Fort McMurray, is economically recoverable by surface mining techniques, the remainder being too deeply situated (750 m) for economic ...

This report presents an analysis of the potential future oil supply capability from the North Sea. Presented herein are estimates of (1) original oil in place; (2) ultimate recovery; (3) remaining recoverable oil; and (4) projected supply patterns over time. This study indicates that the estimated remaining ...

Tables summarize the estimates of recoverable fossil fuels and uranium reserves made by DOE, the US Geological Survey, the National Academy of Sciences, and private companies. They also show how those estimates have changed over a 10-year period. Other estimates project the potential for undiscovered oil and gas reserves and the 90 to 140-year life ...

This paper reports that the location production, and transportation of the 60 million bbl of oil consumed in the world each day is of vital importance to relations between nations, as well as to their economic wellbeing. Oil has frequently been a decisive factor in the determination of foreign policy. The war in the Persian Gulf, while a dramatic example ...

This report is an analysis of discovered crude oil reserves, undiscovered recoverable crude oil resources, and estimated annual oil field production. The countries analyzed are Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, and Peru. All of the countries in this report have a history of petroleum exploration ...

This 64th annual report of the State Oil and Gas Supervisor, California Division of Oil and Gas, presents information on oil and gas operations during 1978. Oil production decreased to 335.2 million bbl in 1978. Production was made from 229 active oil fields with 43,375 oil ...

The Congress expressed concern about the Department of Energy's actions in selling oil from the Elk Hills Naval Petroleum Reserve at what appeared to be unreasonably low prices. DOE officials believe that Naval Petroleum Reserve oil has been and is currently being produced at the appropriate rate and that no recoverable ...

On a percentage basis, more of the world's oil resources have been consumed than the world's gas resources, and in the United States more of the nation's oil resources have been produced than its gas resources, according to an American Gas Association analysis. On a Btu-equivalency basis, U.S. recoverable ...

An economic analysis is reported on four hypothetical heavy oil deposits that were considered to be representative of those found in the Missouri-Kansas border area. Oil production obtainable by various thermal recovery methods was computed for each of the four cases. Development and production costs were estimated, and the oil prices ...

This work discusses the estimates of Mexico's oil reserves in the context of distinctions between oil resources and oil reserves which are proven to be recoverable with present technology and at current prices. Proven reserves of oil in the world total 650 billion bbl, of which ...
