Deflores M. S. #1 (API 42-427-33610) is a well in Starr County operated by Petrovybe Opco LLC, completed September 25, 2004 and listed as shut in on the RRC schedule.

The RRC has issued 2 drilling permits (amended once) between 2003 and 2004, permitted to 11,000 ft.

It was permitted by El Paso Production Oil & Gas CO. and has since transferred to Petrovybe Opco LLC on the wellbore schedule.

Completion filings report 2 formation tops, including Frio, Vicksburg.

Its 5 leases have reported 8.32K barrels of oil and 769K mcf of gas since June 2003, last reporting in July 2026. The leases carry 5 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.
