E3 pilot is & Imperial Well #1....Oil depleted, not a pressure issue. But here's 1 article on that area, from discovery:
1947 and 1948 were banner years for the oil and gas industry in Alberta. The blowing-in of Imperial Oil Well No. 1 (also known as Leduc No. 1) near Devon sparked interest in the province as a source of oil. Several other significant strikes established Alberta as Canada's leading petroleum producer. On January 15, 1948 drilling proved successful at tycoon Frank MacMahon's Atlantic No. 3 well, situated within sight of Leduc No. 1. Oil gushed out of the ground to a height of 150 feet. It was pressured by an estimated 15 million cubic feet per day flow. Such enormous pressure, unregulated by blow-out precautions, led on March 15 to the fracturing of the surrounding area. Natural gas and oil began to escape over a wide radius, causing serious concern and the implementation of emergency measures. On May 15, 1948 the Petroleum and Gas Conservation Board, through an Order-in-Council, took control of the well. Between March and September, over a million barrels of oil were recovered from Atlantic No. 3.
The well ran wild until September 6, when a spark from an unknown source ignited a massive conflagration. Flames leapt more than one hundred feet in the air and billows of acrid smoke could be seen for more than one hundred miles, while the whole atmosphere around most of Alberta was perceptibly darkened. Through the intervention of famous well control specialists Myron Kinley and Red Adair, the blaze was quelled by November, 1948. Major news services reported the story worldwide, and film footage from the Atlantic No. 3 Wild Well Site blaze was featured on the Movietone News in theatres. To the delight of industry leaders, this publicity conveyed the news of Alberta's extensive petroleum resources to the world market and brought international money into Alberta to finance the rapidly expanding oil industry.
