Where is petroleum found Flashcards
Where is petroleum found? Crude oil and natural gas are found in ?? over millions of years by the accumulation of sand, silt, mud and the remains of ?? in ? basins.

sedimentary
Canada has ? distinct regions or domains of sedimentary rocks. Every province and territory includes at least a portion of a ??. These basins cover the majority of the land area of Alberta and Saskatchewan and large areas off the ??

East Coast.
The most productive hydrocarbon area is the ????, which includes most of Alberta and Saskatchewan and parts of British Columbia, Manitoba, Yukon and the Northwest Territories
Western Canada
Sedimentary Basin
In 2003, the Western Canada Sedimentary Basin accounted for 87 per cent of Canada’s crude oil and ? per cent of natural gas production
97
The Geological Survey of Canada (GSC) estimates this basin contained ? per cent of Canada’s original in-place conventional petroleum resources.

This figure (57%) does not include natural gas from coal or the non-conventional bitumen resources of the Alberta ?, the world’s largest known petroleum resource.

Western Canada
Sedimentary Basin
The ?? extends along the East Coast from the U.S. border to the coast of Baffin Island. This area is the site of major offshore crude oil and natural gas deposits discovered since the 1970s
Atlantic Margin
This region’s first crude oil production was from 1992 to 1999 from the Cohasset and Panuke oil fields off Nova Scotia, and much larger oil production began in 1997 from the Hibernia project off Newfoundland and Labrador.
Atlantic Margin
??, another project in the same vicinity, began crude oil production in 2002, and the White Rose project is scheduled to begin production in 2005.
Terra
Nova
This region’s first natural gas
production began in 1999 from the
? Offshore Energy Project off
Nova Scotia.
Atlantic Margin
Sable
The Geological Survey of Canada estimates that the Atlantic Margin contained per cent of Canada’s original in-place conventional petroleum resources. It is an increasingly important contributor to the nation’s petroleum supply
18
Substantial crude oil and natural gas resources have also been identified in the Arctic Islands, ?? and the ??, but development has been slow due to ? land claims, the long distance from markets and the ? of pipeline systems.
Beaufort Sea
Mackenzie Valley

Two regions of sedimentary rocks – the Arctic Margin and the Arctic Cratonic regions – are estimated to hold per cent of Canada’s total conventional petroleum resources. (Cratonic rocks are those that have been relatively undisturbed since ? times, generally found in interior areas of continents.)

pre-Cambrian
The only production to date has been tanker shipments of crude oil from ? to ?from the Bent Horn well in the Arctic Islands (? ? region), and natural gas production from the Ikhil field in the Mackenzie Delta (? ? region) since 1999 to supply the community of ? 50 kilometres away.

One tanker load of crude oil was also shipped to Japan in 1986 following an extended production of the Amauligak discovery well in the ?? (Arctic Margin).
Beaufort Sea
The ? ? region includes
parts of Manitoba, Nunavut, Ontario,
Quebec, the Maritime provinces
and Newfoundland and Labrador.
Eastern Cratonic
this region’s sedimentary
rocks are estimated to contain just two
per cent of Canada’s original in-place
conventional petroleum resources
Eastern Cratonic
One area of Eastern Cratonic rock is the portion of the ? ? that includes an area of southern Ontario and the adjacent Great Lakes. This area has been producing crude oil since the 1850s, and it continues to produce a small portion (less than ? per cent) of Canada’s current crude oil and natural gas supply.
Michigan Basin
one
The ? region is the area of British Columbia and the Yukon located between the Canadian Rockies and the West Coast mountain ranges. There has been some exploration in Intermontane areas, which are estimated to contain ? per cent of Canada’s original in-place conventional petroleum resources.
Intermontane

The ? ? off the B.C. coast is estimated to contain another ? per cent of the nation’s original inplace conventional petroleum resources, but there has been no exploration since ? when the federal and provincial governments imposed ? on offshore oil and gas activities in the area.
