Kan. Admin. Regs. § 82-3-1213 - Operation, monitoring, and measurement requirements for reservoir storage wells
(a) Each
operator shall monitor each reservoir storage well according to a storage well
integrity plan signed by a licensed professional engineer and a licensed
professional geologist. The operator shall submit a storage well integrity plan
that includes information pursuant to, and demonstrates compliance with,
subsections (b) through (i).
(b)
Each operator shall monitor the quality of air to be injected into each
reservoir storage well before the commencement of storage operations and at
least once each 12 months after storage operations commence. The analysis of
the quality of air shall include consideration of fuel-fired turbine exhaust
contaminants.
(c) Each operator
shall evaluate the formation water in the reservoir before commencing storage
operations.
(d) Each operator shall
report the monitoring results for each reservoir storage well to the
conservation division, on a form provided by the conservation division,
annually on or before April 1.
(e)
Each operator shall monitor each reservoir storage well daily. If the reservoir
storage well consistently operates in a manner that appears to be protective of
public safety, usable water, and soil, monitoring on a time frame based on the
air injection and withdrawal cycles may be allowed by the director.
(f) Each operator shall include in the
reservoir storage well integrity plan a description of the equipment,
processes, and criteria used to determine pressure, total volume, and air flow
rate wellhead conditions. Each operator shall monitor and report the pressure,
total volume, and air flow rate. If the reservoir storage well is constructed
with tubing and a packer, the operator shall also monitor and report the
pressure in the annulus between the casing and tubing for any unexpected
increase or decrease.
(g)
(1) Each operator shall ensure that any
reservoir storage well is operated at or below the maximum allowable operating
pressure and based on either of the following criteria:
(A) Site-specific geomechanical core analysis
of the fracture gradient calibrated to the open hole log for each storage well
that determines mechanical rock properties; or
(B) sufficient testing of the
reservoir.
(2) The
operator shall not subject the reservoir to pressures in excess of the maximum
allowable operating pressure associated with abnormal operating conditions,
including pressure pulsations from the electrical generating
facility.
(3) No operator shall
allow the maximum allowable operating pressure to exceed the lower of either 80
percent of the fracture gradient for the storage reservoir or 0.8 pounds per
square inch per foot of depth, measured at the top of the reservoir.
(h) Each operator shall operate
any reservoir storage well within the injection and withdrawal rates based on
casing and tubing limitations, the formation compressibility of the reservoir,
and the flow rate requirements for the electrical generating
facility.
(i) The operator shall
develop an inventory balance plan as part of the reservoir storage well
integrity plan that demonstrates the maximum air injection or withdrawal volume
for each storage well. The storage volume calculations shall include the
cushion air and working air volumes. The operator shall reevaluate the
inventory balance plan whenever an additional storage well is drilled and
completed.
