Приставки СИ

GJ = Гига Джоуль = 10^9 Джоуля
PJ = Пета Джоуль = 10^15 Джоуля

1 т.н.э = 42 GJ

1 000 PJ = 23.81 млн. т н.э.
2 000-10 000 PJ = 47.62-238.1 млн. т н.э.
25 000-50 000 PJ =595-1190 млн. т н.э.
100 000-250 000 PJ = 2381-5952 млн. т н.э.
500 000 PJ = 11905 млн. т н.э.

ga.gov.au: Distribution of Australian indicated shale oil resources

Oil shale is a fine-grained sedimentary rock containing large amounts of organic matter (kerogen), which can yield substantial quantities of hydrocarbons. Oil shale is essentially a petroleum source rock which has not undergone the complete thermal maturation required to convert organic matter to oil. In addition, the further geological processes of hydrocarbon migration and accumulation which produce conventional crude oil resources trapped in subsurface reservoirs has not occurred. The unconventional shale oil resource can be transformed into liquid hydrocarbons by mining, crushing, heating, processing and refining, or by in situ heating, oil extraction and refining. One tonne of commercial grade oil shale may yield from about 100 to 200 litres (L) of oil, that is approximately a half to one barrel of shale oil per tonne of oil shale.

Australia has a large unconventional and currently non-producing identified shale oil resource of 131 600PJ (22 390mmbbl) which could potentially contribute to future oil supply if economic and environmental challenges can be overcome. The majority of Australian shale oil resources of commercial interest are located in Queensland, in the vicinity of Gladstone and Mackay. Thick Cenozoic lacustrine oil shale deposits (lamosite) of commercial interest are predominantly in a series of narrow and deep extensional basins near Gladstone and Mackay. Oil shale deposits of varying quality also occur in New South Wales, Tasmania, and Western Australia in sedimentary sequences of Permian, Cretaceous and Cenozoic age.

ga.gov.au: Australian Operating Mines, June 2012

This map shows operating mines, developing mines and selected mineral deposits in Australia. Operating mines are mines that were operating at the end of 2011. Developing mines are deposits with a proven minable resource and where mine site development has commenced or where a decision to mine has been announced. Mineral deposits highlight selected areas of known mineralisation of interest. The map illustrates broadly the geographic distribution of the mines and deposits, and the range of selected broadly grouped commodities. This information is superimposed on a generalised (colour) surface geology map of Australia overlain by aeromagnetics (greyscale, 0.5 vertical derivative). Closed mines or mine not currently operating are not shown.

ga.gov.au: Maritime Boundary Definitions

A nautical mile (M) is a unit of distance equal to 1 852 metres. This value was adopted by the International Hydrographic Conference in 1929 and has subsequently been adopted by the International Bureau of Weights and Measures.

The length of the nautical mile is very close to the mean value of the length of 1 minute of latitude, which varies from approximately 1 843 metres at the equator to 1 861.6 metres at the pole.
