Wes Rabey

Get To Know Our Founder

Sprouting from humble beginnings, Sigma Explorations was founded in 1966 by our first president Wes Rabey. Having set the foundation of his career with Imperial Oil in 1945, Wes quickly became an influential member in the advancement of the geophysical industry. His contributions range vastly from founding Accurate Geophysical in 1950 to conducting the first participation survey in the history of the industry. In recognition of such achievements, Wes was inducted into the Canadian Petroleum Hall of Fame in 1998. Wes passed away at the age of 99 in June of 2021.
