SECTION 165:10-17-6. General well testing requirements

(a)   All single-point and multi-point potential tests shall be calculated for all non-exempt gas wells in a uniform manner with respect to the following:

(1)   The potential shall be the calculated wellhead absolute open flow potential of the well determined by obtaining a static column wellhead flowing pressure and shall indicate the capacity of the well to produce against zero psia at the wellhead.

(2)   All pressures used in test calculations shall be corrected to pounds per square inch absolute, using 14.4 psia as the average barometric pressure.

(3)   The static column wellhead pressure, either measured or calculated as reported in the potential test, shall be no more than 90 percent of the wellhead shut-in pressure. If data cannot be obtained in accordance with the foregoing provisions, an assumed static column wellhead pressure of 90 percent of the wellhead shut-in pressure shall be used to calculate the results of the test. This paragraph supersedes any contrary provision in special pool rules.

(b)   The operator of a well shall be responsible for testing the well and submitting the test results to the Conservation Division. The results of a potential test shall be filed with the Conservation Division on Form 1016. If the operator wishes to obtain a copy of the approved Form 1016, he shall enclose with the original form a self-addressed stamped envelope and one additional copy of the test and/or form. The Conservation Division shall acknowledge such requests within 15 days, stating either the date of acceptance of the test results or rerunning the original test if it has been rejected. If any order or rule of the Conservation Division requires witnessing of a test, the operator of the well shall be responsible for securing the presence of an authorized Conservation Division representative to witness the test and sign the Form 1016 for the test.

(c)   Unless otherwise prescribed by special pool rules, field testing procedure shall be performed in accordance with the procedures set out in Oklahoma Corporation Commission Manual of Back-Pressure Testing of Gas Wells, Parts I and II, utilizing the specified tables in the Interstate Oil and Gas Compact Commission Manual of Back-Pressure Testing. A gas turbine meter may be used in lieu of an orifice meter for flow measurements in gas well testing.

(d)   The initial test for all gas wells shall be run into the pipeline within 30 days and test results filed within 45 days after the date of first sales of gas. Any test filed after the 45 day limit will not be made effective until the first of the month following the date of acceptance of the test. With regard to initial tests for special allocated gas wells, the operator of the well shall provide twenty-four (24) hours notice to the Conservation Division of its intent to run an initial test in order to give the Conservation Division the opportunity to witness said test, but in no case shall the operator be precluded from performing said test and filing the results as provided for in subsection (b). Initial tests for special allocated gas wells need not be witnessed, nor signatures obtained, if witnessed, in order for the Conservation Division to assign an allowable to said well. Initial tests for unallocated gas wells with calculated open flow of less than two million cubic feet per day are exempt from witnessing by Conservation Division personnel under 165:10-17-7(b)(1).

(e)   The annual test for all non-exempt gas wells shall be run into a pipeline in accordance with this Section or applicable pool rules. Any annual test for a well in a special allocated pool, filed late shall not be made effective until the first of the month following the date of acceptance of the test.

(g)   Wells in allocated pools shall be tested in accordance with the requirements for wells in unallocated pools, unless superseded by specific field rules. Form 1016 shall be used to report shut-in pressure tests on wells in allocated and special allocated pools, except for the Guymon-Hugoton Pool #182 which shall use a form 1017 Deliverability Gas Test.
