The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.

Chain of custody

Operator on the lease's P-4

Each operator named on the P-4 filings for this well's lease (a gas well is its own lease), from the date its filing took effect. The P-4 is filed by lease, so a date before the well was drilled is the lease's.

"Spans" is by this well's own filed formation tops: a formation runs from its top to the next deeper top filed, and the deepest runs to the bottom of the log. Depths are measured along the wellbore, so on a horizontal the lateral counts in the formation it was landed in.

These are the logs loaded into Petrora from the Railroad Commission's inventories, not necessarily every log run on the well. The RRC holds the files; each opens from its log search for the well. The kind is the RRC's description of the log; the interval is the one filed for it.
