Wellbores on record

OCC well records list 14 open wellbores (8 oil, 3 gas and 3 injection or disposal) with a surface location in this section, plus 6 plugged.

Wellbores are counted by surface location. A horizontal well drilled from a neighboring section can produce from this one without being counted here; the orders above are the better guide to that.
