Central Levelland Unit #321 (API 42-219-37007) is a well in Hockley County operated by Occidental Permian Eor LLC, completed January 3, 2024 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit, issued September 25, 2007, permitted to 4,931 ft.

It was permitted by Occidental Permian Ltd. and has since transferred to Occidental Permian Eor LLC on the wellbore schedule.

Completion filings report 6 formation tops, including Rustler, Yates, Seven Rivers, Queen.

Its lease has reported 12.3M barrels of oil and 4.28M mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 314 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 135K barrels injected in the 12 months reported through February 2026.

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 Aug 27, 2008. 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.
