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

Oklahoma files 1 application to drill this well, naming 6 target formations. A permit records what an operator asked to do, not what it did. A target formation is where the operator aimed, and the hole may have missed it, stopped short of it or never been drilled.
