36.25.234 SEISMOGRAPH PLUGGING AND ABANDONMENT
(1) Except as hereinafter provided, all
seismic holes shall be plugged as soon after being utilized as reasonably
practicable; however, in no event shall they remain unplugged for a period of
more than 120 days after being drilled and shot.
(2) The permittee shall notify the
department, in writing, of its intent to plug and abandon, including the date
such activities are expected to commence, the location by section, township,
and range of the holes to be plugged and the name and telephone number of the
person in charge of the plugging operations.
(3) All seismic shot holes shall be plugged
in accordance with the board of oil and gas conservation rules. All cuttings
not placed in the hole shall be spread out over the surrounding area at a depth
not to exceed 1 inch.
(4) If an artesian water flow is
encountered in any of the drill holes located on state land, the permittee
shall immediately notify the department so that a decision can be made by the
department as to whether the well will be developed. The department shall make
a decision within 24 hours of notification. If the well is not developed, or
if damage is occurring or is imminent, it is the permittee's responsibility to
plug the hole with cement of sufficient density to contain the waters to their
native strata as required by the board of oil and gas con-
servation rules. If a nonflowing aquifer is encountered in any of the drill holes on
state land, the permittee shall notify the department in writing of the
location and depth.
(5) The permittee shall leave the land covered by the permit in as nearly the same
condition as it was prior to the effective date of the permit as is practically
possible. All refuse, including, but not limited to, oil cans, shot wire,
powder boxes, flagging, cement or mud sacks, stakes, and primacord shall be
removed from the lands and shall be properly disposed of by the permittee.
(6) A seismic shot hole may be left unplugged at the request of the surface lessee or
owner for conversion to a fresh water well provided the surface lessee or owner
executes a release on a form provided by the department relieving the permittee
from any liability for damages that may thereafter result from the hole
