The results must be reported to the commission on a Reservoir Pressure Report (Form 10-412).(b) The operator shall obtain fluid samples from each new pool at the time of discovery or before regular production and determine (1) crude oil composition;(2) pressure, volume, and temperature properties of the crude oil; and(3) solution or non-associated gas composition.(c) Sampling and analysis must be conducted and reported in accordance with good oil field engineering practices. Reports must be submitted to the commission within 45 days following the completion of the determinations required in (b) of this section.(d) The operator shall determine within three months after discovery of each new oil pool the original solution gas-oil ratio by a well test conducted in a manner approved by the commission. The operator shall report the results on the Well Status Report and Gas-Oil Ratio Tests (Form 10-409) within 45 days after the test.(e) Annually and not later than April 1 or the date that the operator must submit a poolspecific annual surveillance report for the reservoir under 20 AAC 25.520, whichever date is later, the operator shall submit to the commission an Annual Reservoir Properties Report (Form 10-428).Eff. 4/13/80, Register 74; am 4/2/86, Register 97; am 11/7/99, Register 152; am 2/10/2018, Register 225, April 2018
