Universal Citation: OK Admin Code 165:10-17-7
Current through Vol. 41, No. 13, March 15, 2024
(a) Wells in special allocated pools.
(1) An
initial test shall be filed for each newly completed gas well in each special
allocated pool. The well shall be tested into a pipeline no later than 30 days
after the date of the first sale of gas. Test procedures shall be those
specified in the applicable pool rules subject to the uniform requirements of
165:10-17-6.
(2) An annual test shall be filed in
accordance with the requirements of the applicable pool rules, subject to the
following provisions specific to the Guymon-Hugoton special allocated
pool.
(3) Wells in the
Guymon-Hugoton special allocated pool.
(A)
The Conservation Division staff will not be required to witness any well test
on any well in the Guymon-Hugoton special allocated gas pool unless requested
to do so by an offset operator. Operators have a right to witness any well test
on any well offsetting said operator's well in the pool. Operators of
offsetting wells will be given sufficient prior notice of testing to allow for
a representative to be present to witness testing, and will be provided access
to the designated witness throughout testing.
(B) Wells in the Guymon-Hugoton special
allocated gas pool which are not capable of producing 450 Mcf/day will be
exempt from biannual deliverability tests. Operators shall have the right to
elect to receive the minimum allowable by deciding not to conduct well
deliverability tests on any such wells in the pool. No well shall be exempt
from the annual wellhead shut-in pressure test requirements. For the purpose of
the annual wellhead shut-in pressure test, the shut-in pressure shall be
measured after the well has been shut-in for approximately 48 hours. In no case
shall the well have been shut-in for less than 44 hours at the time the shut-in
pressure is taken.
(b) Wells in unallocated pools.
(1)
Testing of newly completed or newly
recompleted wells.
(A) An initial test
shall be submitted to the Conservation Division for each newly completed gas
well or recompleted gas well involving a new formation in an unallocated gas
pool under
165:10-17-2. The well shall be
tested into a pipeline no later than 30 days after the date of first sale of
gas into a pipeline. The flow period for the initial test shall be 24
hours.
(B) It shall not be
necessary for the operator to submit the initial flow potential test for an
unallocated well with a maximum flow rate of less than the minimum allowable.
Only a current 24-hour wellhead shut-in pressure is required, unless otherwise
requested by the Commission. A copy of the Form 1002A Completion Report may be
submitted in lieu of Form 1016 to establish the minimum allowable, provided the
section on the Form 1002A Completion Report requesting a minimum gas allowable
is explicitly marked, and the following items are reported:
(i) current 24 hour shut-in
pressure;
(ii) date of first sales
and date of recompletion, if applicable;
(iii) Oklahoma Tax Commission production unit
number; and
(iv) name of reporting
entity of monthly gas volumes for the well (either the purchaser/measurer, or
self-reporting operator). If the required information is not provided on the
Form 1002A Completion Report submitted to the Commission, an initial test on
Form 1016 containing the information must be filed with the Commission to
establish an initial allowable for the well.
(C) An initial potential test is required to
receive an allowable greater than a minimum allowable. The established
allowable shall be from the date of first sales of gas, provided that a
complete and correct Form 1002A Completion Report for the well is filed with
the Commission within 60 days after the date of first sales. If the Form 1002A
Completion Report is filed with the Commission after the 60 day period, the
allowable will become effective on the first day of the month in which the Form
1002A Completion Report is approved by the Commission. A request to extend the
time to test may be granted by the Conservation Division in order to recover
fluids introduced into the well. The request shall be submitted in writing to
the Conservation Division with the expected test date.
(2)
Testing or retesting of established
gas wells. A potential test to assign a new allowable for an initially
tested well may be submitted on Form 1016 at any time after three months from
the date of the initial test. To establish or maintain an allowable greater
than the minimum allowable after the initial potential test, a potential test
shall be run at least once every 12 months for the first two years, and every
two years thereafter. The established allowable from any potential test shall
be valid within that specific 12-month or two year period, based on the
appropriate anniversary dates of the first gas sales of the well. The Director
of the Conservation Division may require additional tests at any time. Tests
become effective the first day of the month following acceptance of the test by
the Conservation Division.
(A) Unless
specifically requested by the Director of the Conservation Division, it shall
not be necessary to run a potential test or retest for an established well
having a flow rate of less than the minimum allowable.
(B) Upon expiration of a potential test, the
well will revert to a minimum allowable status, unless superseded by a later
potential test.
(C) If two or more
potential tests are submitted for a well, and the effective periods of the
tests overlap or conflict, the test having the greatest calculated open flow
potential shall be utilized to determine the well's allowable for the
overlapping period.
(3)
One-point tests. The potential test required for each gas well in
each unallocated pool shall use the one-point back pressure method and an
assumed flow characteristic of 0.85 shall be used in establishing the wellhead
absolute open flow. The test shall be governed by the requirements of OAC
165:10-17-6.
(4)
Durability of minimum
allowable. Once an initial allowable is established for a well, that
well shall be assigned at least a minimum allowable until such time the well is
plugged, reclassified, recompleted or commingled into an additional formation,
or is found to be in violation of a rule or order of the Commission. If a
potential test is submitted for the well, that test will supersede the minimum
allowable for the effective period of the test set out herein.
(5)
Test exemptions for certain minimum
wells.
(A) The following types of gas
wells shall be exempt from initial and annual potential and shut-in tests:
(i) Minimum gas wells producing exclusively
from coal bed methane formations.
(ii) Minimum gas wells producing from shale
formations or including shale formations, if commingled.
(iii) Minimum gas wells using down hole pumps
for artificial lift of produced liquids.
(iv) Minimum gas wells producing less than
100 mcf/day.
(B) For
these exempt wells operators shall report the initial stabilized rate of
production on Form 1002A "Completion Report" in lieu of reporting an initial
test on Form 1016 "Backpressure test for Natural Gas Wells".
(6)
Alternate shut-in
pressure. The Conservation Division may allow the equivalent of the
24-hour shut-in pressure required in this Section and in OAC
165:10-17-6 to be derived from
accepted industry methodologies if the operator sufficiently demonstrates to
the Division that such calculations will result in an appropriate
representation of the actual 24-hour shut-in pressure.
(7)
Minimum compliance. Each
operator shall be responsible for conducting and submitting the required
potential tests on the applicable form. All submitted tests must contain
complete and accurate information. Permitted production rates will be granted
only to those wells which meet this requirement and all other rules or orders
of the Commission.
