EXPERIENCED WELLSITE GEOLOGISTS SERVING CANADA AND INTERNATIONALLY FOR OVER 35 YEARS

Belloy Geologists is a Calgary, Alberta, Canada based privately owned company providing geological wellsite services now for over 35 years. Belloy Geologists was first incorporated in 1979 by Robert K. Sullivan (P.Geol.) to provide on-site geological supervision during the drilling of oil and gas wells in the Western Canadian Sedimentary Basin. With a focus on providing quality service and dependable client support both in the field and in the office, Belloy’s wellsite geologists have developed long term relationships with hundreds of clients over the years that translated into many repeat opportunities to provide professional geological coverage.
