353.080 Drilling through coal bed.
(1)
(2)
A well penetrating one (1) or more workable coal beds shall be drilled in such
manner as will, if practicable, exclude all oil, gas or gas pressure from the coal
bed, except such as is found in the coal bed itself. Each string of casing that is
run through a workable coal bed shall be seated at least thirty (30) feet below
the coal bed in twenty (20) feet of cement, mud, clay or other nonporous
material that will make an effective seal. If a second workable coal bed is found
less than thirty (30) feet below the first workable coal bed, the casing shall be
seated and mudded off as above provided at least thirty (30) feet below the
second bed. If gas is found between the two (2) beds, it shall be treated as
prescribed by KRS 353.090. After any such string of casing has been properly
seated, drilling may proceed immediately.
When a well is drilled through the horizon of a coal bed where the coal has
been removed, the hole shall be drilled at least thirty (30) feet below the coal
bed, and shall be of a size sufficient to permit the placing of a liner, which shall
start not less than twenty (20) feet beneath the horizon of the coal bed and
extend not less than twenty (20) feet above it. Within this liner, which may be
welded to the casing to be used, shall be centrally placed the largest size
casing to be used in the well, and the space between the liner and the casing
shall be filled with cement as the liner and casing are lowered into the hole.
Cement shall be placed in the bottom of the hole to a depth of twenty (20) feet
to form a sealed seat for both liner and casing. Following the setting of the
liner, drilling may proceed. If it is necessary to drill through the horizon of two
(2) or more coal beds where the coal has been removed, the liner shall be
started not less than twenty (20) feet below the lowest horizon penetrated and
shall extend to a point not less than twenty (20) feet above the highest horizon
penetrated.
