Wellbore
Utah holds the directional survey of this hole as it was drilled.
Utah filed 61 stations for this well. The 5 shown are the ones that carry the shape: every station left out lies within 25 ft of the line drawn through the ones kept. The reach and bearing are derived from two points Utah filed. Neither is a figure the operator reported.
Work history
Utah files 1 record of work done on this well — each drill, plug, deepening, re-entry, re-perforation and recompletion, with the depths reached. One carries a production test the operator filed afterwards.

A production test is one measurement the operator made on one day and filed with Utah. It is not a monthly average and it does not describe how the well produced afterwards. The choke size is shown exactly as filed: Utah 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 Utah did not file, or one it filed outside any physically possible range.
