Xrl #4 (API 42-413-30817) is a well in Schleicher County operated by Discovery Operating Inc., completed October 17, 1990 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued July 30, 1979, permitted to 6,900 ft.

It was permitted by Crown Central Petroleum Corp. and has since transferred to Discovery Operating Inc. on the wellbore schedule.

Completion filings report 5 formation tops, including San Angelo, Wolf Camp, Canyon, Upper Henderson.

Its lease has reported 60.4K barrels of oil and 705K mcf of gas since January 1993, last reporting in July 2026. The lease carries 6 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.
