Rule 26-2-1.41 - DELIVERABILITY AND ROUTINE PRODUCTION TESTS(a) A deliverability test of each producing gas well shall be made in conformity with schedules issued by the Board. Such test shall be an actual test to determine whether or not the well is capable of producing efficiently any allowable that may reasonably be expected to be assigned to it, and, if the well is not found to be capable, then the test shall determine the maximum rate at which the well may efficiently be produced. The method of testing used shall be one acceptable to the Board. A report of each test so required shall be furnished to the Board upon Form No. 4-A within fifteen (15) days after the test is completed. Any operator may make such additional deliverability tests at any time and report such tests to the Board in the same manner as required tests are reported. Deliverability shall be determined by the latest test information furnished to the Board.(b) Each oil well and each oil completion of a multiply- completed well shall be tested by the operator once during each calendar month during each calendar year in a calibrated stock tank.MCA Section 53-1-17(3) (1972)
