An Attempt to Increase the Permeability and Porosity of the Cut Bank Oil Sand By Treatment with Various Reagents

The purpose of this investigation was to attempt to find some means of increasing the effective porosity and permeabil­ity of the producing sands of the Cut Bank Oil Field, with the hope that thereby the ultimate recovery of petroleum from this field may be increased. Although the percentage increase in production thus effected would undoubtedly be small, it would represent a substantial volume of petroleum in view of the great quantity of oil and gas present in this field.
