Current through Register Vol. 43, No. 12, March 20, 2024
(a) Any
operator may plug any storage well pursuant to a well plugging plan signed by a
licensed professional engineer or licensed professional geologist. Each
plugging plan for a cavern storage well shall also be signed by a licensed
professional land surveyor. The operator shall submit the plugging plan to the
conservation division at least 60 days before the anticipated plugging
date.
(b) Each operator submitting
a plugging plan for any cavern storage well shall include the following:
(1) The portion of the safety and emergency
response plan specified in K.A.R. 82-3-1216 that is applicable to the well
plugging plan;
(2) a wellbore
schematic of the storage well to be plugged;
(3) the updated local geological evaluation
specified in K.A.R. 82-3-1208(h) and the updated layout of the storage facility
specified in K.A.R. 82-3-1208(i);
(4) a record of each historical internal and
external mechanical integrity test, salt roof thickness evaluation log, cement
evaluation log, casing inspection log, and sonar survey for the storage
well;
(5) evidence regarding
whether the wellhead pressure for the cavern storage well has stabilized
according to the plugging-monitoring status plan;
(6) procedures to set a mechanical bridge
plug or other control device in the long string casing;
(7) procedures to place a cement plug above
the storage cavern by a method that will prevent migration of fluid into or out
of the storage cavern;
(8)
procedures to establish a monument at the surface for elevation survey purposes
for monitoring ground subsidence;
(9) procedures to perform land surveys every
two years until the storage facility is abandoned pursuant to commission
regulations; and
(10) a reasonable
estimate of the cost to plug each cavern storage well currently in
plugging-monitoring status.
(c) The operator of a cavern storage well
shall perform additional testing or logging before plugging the cavern storage
well if required by the conservation division due to the absence of current
logs or tests or due to a lack of mechanical integrity of the cavern storage
well that could result in a threat to public safety, usable water, or
soil.
(d) Each operator shall plug
any cavern storage well in plugging-monitoring status according to the plugging
plan if both of the following conditions are met:
(1) The cavern storage well has been in
plugging-mon-itoring status for at least five years.
(2) The director determines that the cavern
storage well has been stabilized according to the plugging-monitoring status
plan.
(e)
(1) Each operator submitting a well plugging
plan for any reservoir storage well shall include the following:
(A) The portion of the safety and emergency
response plan specified in K.A.R. 82-3-1216 that is applicable to the well
plugging plan;
(B) a wellbore
schematic of the storage well to be plugged;
(C) the updated local geological evaluation
specified in K.A.R. 82-3-1208(h) and the updated layout of the storage facility
specified in K.A.R. 82-3-1208(i);
(D) a record of each historical internal and
external mechanical integrity test, cement evaluation log, and casing
inspection log;
(E) procedures to
set a mechanical bridge plug or other control device in the long string
casing;
(F) procedures to place a
cement plug above the storage reservoir by a method that will prevent migration
of fluid into or out of the storage reservoir; and
(G) a reasonable estimate of the cost to plug
each reservoir storage well.
(2) The operator shall perform additional
testing or logging before plugging the reservoir storage well if required by
the conservation division due to the absence of current logs or tests or due to
a lack of mechanical integrity of the reservoir storage well that could result
in a threat to public safety, usable water, or soil.
(f) Each operator shall plug any storage well
within a time frame specified by the director if the director determines that
the storage well presents a danger to public safety, usable water, or
soil.
(g) Each operator shall
submit a well plugging report within 30 days after plugging any storage well.
This report shall contain the following information:
(1) The date the storage well was drilled and
completed;
(2) the location of the
storage well;
(3) the method used
to plug the storage well; and
(4)
any other information that is necessary to allow the director to determine
whether the well was plugged in a manner that will protect public safety,
usable water, and soil.
