Results and Significance of Drilling Operations in the Athabaska Bituminous Sands

CIM Bulletin, 1947


DR. K. A. CLARK(1) : No one will doubt the statement of fact that, during drilling operations through the bituminous sand beds in the Mildred-Ruth Lakes area, the core-barrel was found to contain bitumen with minor amounts of sand instead of bituminous sand. But many will doubt the interpretation of this fact as meaning that beds of bitumen occur interstratified with the bituminous sand beds.
