A dash is a period the well filed with no volume for that product. This corpus holds Utah’s series from 2025; the Division publishes earlier years in a separate set of files.
Wellbore
Utah holds the directional plan this operator filed before drilling, not a survey of the hole as drilled.
This is the path the operator proposed. The hole may not have been drilled along it, and Utah has filed no survey of the hole as drilled for this well. Utah filed 210 stations for this well. The 8 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.
