Attached for your review is the 2016 Annual Performance Evaluation for the Sterling Pool 6
Gas Storage Reservoir according to SIO #7. This report covers the primary production and
injection period through the 2016 gas storage operations.
Sterling Pool 6 continues to exhibit tank like behavior with neither influx of other fluids nor
loss of storage gas based on the evidence shown in the exhibits below. Injection wells
continue to act as expected based on an injectivity index. Real time downhole pressure
monitoring is possible with shut in tubing pressures of KU 34-31 corrected to reservoir
pressure.
For the annual period ending 12/31/2016 the total volume injected into Sterling Pool 6 was
7,891 MMSCF and production was 3,065 MMSCF. The total native gas withdrawn from
Pool 6 was 1,532 MMSCF with a native gas balance of 1,269 MMSCF. The maximum
reservoir pressure recorded in Pool 6 based on the KU 34-31 monitoring well SITP (shut in
tubing pressure) was 214 psi or a reservoir pressure of 238 psi. This pressure is expected to
be distributed consistently throughout the productive area of Pool 6 and is below the
maximum reservoir pressure of 300 psi as established by rule #4 of SIO 7.
