Title: Developments in Eastern Canada in 1971

Author(s): R. D. Howie (2), J. V. Hill (3)

Abstract:

The production of natural gas and petroleum in eastern Canada during 1971 was 16,410,852 Mcf of gas and 967,898 bbl of oil. This represents a decrease of 433,648 Mcf (2%) of gas and a decrease of 89,945 bbl (8%) of oil from the previous year.

In the Hudson Bay region, industry and various government agencies completed 10¼ crew-months of combined geologic and geophysical work. Three shallow stratigraphic tests were drilled on land in the James Bay area of Ontario.

In the Foxe basin area of the eastern Arctic, a 1,745 ft stratigraphic test was completed on Rowley Island.

In southwestern Ontario, 63 exploratory tests and 66 development wells were completed during 1971, a decrease of 7 exploratory and 32 development wells from the previous year. A rapid decline in Silurian development drilling, both onshore and in Lake Erie resulted in a 19% decrease in total footage drilled in 1971. Of the 7 significant Silurian gas discoveries, 3 were in Lake Erie. The overall exploratory success increased by 59% over the past 2 years.

In Quebec 5 exploratory holes were completed. Geologic and geophysical surveys totaled 41½ crew-months by industry and 30 by government agencies.

In the Atlantic provinces, activity was again focused in the offshore, where 19 holes were drilled, resulting in a gas and oil discovery on the western tip of Sable Island, 175 mi east of Halifax, Nova Scotia. Interest in the Atlantic continental shelves continues to grow as indicated by an increase in offshore holdings from 312,695,622 acres in 1970 to a new all-time high of 387,492,305 acres in 1971, an increase of 23%. In the offshore, industry accounted for 70½ crew-months of geologic and geophysical activity and 18,996 line-mi of geophysical surveys; whereas government and scientific institute activity accounted for an additional 25 crew-months.
