Stability analysis of a deep hole in the east channel of the Mackenzie Delta, Northwest Territories
Due to the discovery of vast quantities of hydrocarbon reserves in the late 1960s, exploration of the Mackenzie Delta led to the detection of several anomalous deep holes. The proposed pipeline from the Mackenzie Delta-Beaufort Sea region to Alberta has renewed interest in studying the stability of...
