Culberson -X- Fee #4 (API 42-109-31569) is a well in Culberson County operated by Echo Energy Partners LLC, completed October 14, 2025 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued March 19, 1982, permitted to 3,600 ft.

It was permitted by Texaco Inc. and has since transferred to Echo Energy Partners LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Lamar, Cherry Canyon, M. Cherry Canyon.

Its lease has reported 124K barrels of oil and 110K mcf of gas since January 1993, last reporting in July 2026. The lease carries 12 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.
