Cedar Lake Unit #607 (API 42-165-35388) is a well in Gaines County operated by Occidental Permian Eor LLC, completed April 17, 2025 and listed as injection on the RRC schedule.

The RRC has issued one drilling permit, issued February 8, 1999, permitted to 4,950 ft.

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

Completion filings report 5 formation tops, including Rustler, Yaes, Yates, Grayburg.

Its lease has reported 52.7M barrels of oil and 120M mcf of gas since January 1993, last reporting in July 2026. The lease carries 424 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit, with 36K barrels injected in the 12 months reported through October 2025.

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