Briscoe Catarina South #27HW (API 42-127-38524) is a horizontal well in Dimmit County operated by Javelin Energy Partners Mgmt LLC, completed September 29, 2023 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued May 19, 2022, permitted to 7,755 ft.

It was permitted by SN EF Maverick, LLC and has since transferred to Javelin Energy Partners Mgmt LLC on the wellbore schedule.

Completion filings report 10 formation tops, including Escondido, Olmos, San Miguel, Anacacho.

Its lease has reported 2.01M barrels of oil and 7.51M mcf of gas since January 2023, last reporting in July 2026. The lease carries 17 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.
