Big El 45-04 D #4SA (API 42-227-41663) is a horizontal well in Howard County operated by Crescent Energy Operating LLC, completed December 19, 2022 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued March 22, 2022, permitted to 9,000 ft.

It was permitted by Laredo Petroleum, Inc. and has since transferred to Crescent Energy Operating LLC on the wellbore schedule.

Completion filings report 11 formation tops, including Salado, Yates, Seven Rivers, Queen.

Its lease has reported 751K barrels of oil and 2.05M mcf of gas since July 2022, last reporting in July 2026. The lease carries 3 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.
