Section 0400-53-01-.04 - GAS/OIL RATIO TESTS

(a) Gas production potential tests shall be made on the Gas Well Deliverability Tests (Form R-DT-1) and submitted as prescribed above to the Supervisor, and conducted every three years until the well is plugged and abandoned when requested by the Supervisor.

(b) Gas wells shall not be tested by the "open-flow" method. The back-pressure method of determining the open-flow, as outlined by the Bureau of Mines in their Monograph 1, "Back-Pressure Data on Natural Gas Wells", shall be used. When for any reasons, the completed back-pressure method is not feasible, an acceptable method, not entailing excessive physical waste of gas may be used upon recommendation of the Department.

(c) Gas/Oil (c: Gas/Condensate) ratios shall be reported on Form CN-0221.

(d) In the event any operator considers that, for the purpose of determining field allowable, his well has not had a fair determination of its gas/oil ratio, or that its gas/oil ratio has changed because of natural causes or corrective work on his well, he may make application in writing to the Supervisor for a re-test or a special test of the gas/oil ratio of his well, and for an adjustment of his well if applicable. If, upon re-testing a well, the Supervisor finds that the new gas/oil ratio justifies a change in the allowable, he is authorized to make such change.
