Opie C #9 (API 42-135-39860) is a well in Ector County operated by Diamondback E&P LLC, completed May 1, 2018 and listed as shut in on the RRC schedule, shut in October 1, 2022.

The RRC has issued one drilling permit, issued May 19, 2009, permitted to 10,360 ft.

It was permitted by Devon Energy Production CO, L.P. and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Completion filings report 5 formation tops, including San Andres, Clear Fork, Spraberry, Wolfcamp.

Its 2 leases have reported 466K barrels of oil and 1.05M mcf of gas since September 2007, last reporting volume in February 2026. The leases carry 14 wells, so these are lease totals, not this well alone.

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

Well logs

1 log loaded from the RRC's log index, the latest received Jul 21, 2010. Density, Neutron. 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.

"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.
