The first well to be fractured in Canada was the discovery well of the giant Pembina oil field in 1953 and since then over 170,000 wells have been fractured. The Pembina field is a "sweet spot" in the much larger Cardium Formation , and the formation is still growing in importance as multistage horizontal fracturing is increasingly used.
In June 2010, Apache Canada began drilling a horizontal well to tap the Lower Carboniferous Frederick Brook Shale, near Sussex, New Brunswick. Apache is in a joint venture with Halifax-based Corridor Resources Inc., which has extensive leasehold in the province. Corridor has drilled two vertical wells that tested gas from the Frederick Brook. [38]
Drilling an oil and gas well at a location or well pad site at which drilling has occurred previously within five (5) years prior to the date of spudding the well. 3. Drilling an oil or gas well within a developed field for which an approved land use plan or any environmental document prepared pursuant to NEPA analyzed such drilling as a ...
States require a drilling permit before a well begins drilling. Requirements to receive drilling permits generally include minimum setbacks from lease or unit boundaries, and adequate casing and cementing programs. States generally require permits for or notices of major work done on a well, and periodic reports of oil and gas produced.
The status of Canada as an oil importer from the US suddenly changed in 1947 when the Leduc No. 1 well was drilled a short distance south of Edmonton. Geologists realized that they had completely misunderstood the geology of Alberta, and the highly prolific Leduc oil field, which has since produced over 50,000,000 m 3 (310,000,000 bbl) of oil ...

Hydraulically fractured wells are today the source of most of German natural gas production. [ 35 ] In February 2013, the government of Chancellor Angela Merkel announced draft regulations that would allow for the exploitation of shale gas deposits using the same fracking techniques common in the U.S., with the exception only of wetland areas ...
When a petroleum license is granted, the company or joint venture is given a limited time for the exploration of the license. If after the limited time, the company has not discovered or performed its minimal obligations (usually agreed with the government as a minimum number of exploration wells and investment on seismic ) the license will be relinquished.
