A production test is one measurement the operator made on one day and filed with Oklahoma. It is not a monthly average and it does not describe how the well produced afterwards. The choke size is shown exactly as filed: Oklahoma records it in inches on some reports and in sixty-fourths of an inch on others, and names the unit on neither. A dash is a measurement Oklahoma did not file, or one it filed outside any physically possible range.

Drilling permit
