Kentucky Revised Statutes Title XXVIII. Mines and Minerals § 353.090.Gas found beneath or between coal beds

If gas is found beneath a workable coal bed before the hole has been reduced from the size it had at the coal bed, a packer shall be placed below the coal bed and above the gas horizon, and the gas by this means diverted to the inside of the adjacent string of casing through perforations made in the string of casing, and through it passed to the surface without contact with the coal bed. If gas is found between two (2) workable beds of coal, in a hole of the same diameter from bed to bed, two (2) packers shall be placed with perforations in the casing between them, permitting the gas to pass inside the adjacent casing to the surface. The strings of casing shall in either case extend from their seats to the top of the well.
