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

Conocophillips Company's other wells filed under this lease name in Webb County, newest permit first. The RRC gives a gas well its own lease number, so the name is what joins the wells of a unit.

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.
