Any well drilled for oil, gas, saltwater disposal or any other purpose in connection with the production of oil and gas, through a workable vein or seam of coal shall be drilled in such manner as will, if practicable, exclude all oil, gas or gas pressure from the coal seam, except such as is found in the coal seam itself. Each string of casing that is run through a workable coal seam shall be seated at least thirty (30) feet below the coal seam in twenty (20) feet of cement, to form an effective seal, or the coal seam shall be protected in such other manner as may be approved by the Corporation Commission of the State of Oklahoma.
