Dielmann #2
Starr County · Samano (Third Massive) field · SWR-10-Well · Vertical
Dielmann #2 (API 42-427-33440) is a well in Starr County operated by Petrovybe Opco LLC, completed May 24, 2002 and listed as swr-10-well on the RRC schedule, shut in July 1, 2026.
The RRC has issued one drilling permit (amended twice), issued January 28, 2002, permitted to 9,825 ft.
It was permitted by Thorp Petroleum Corporation and has since transferred to Petrovybe Opco LLC on the wellbore schedule.
Completion filings report one formation top, including Frio.
Its 2 leases have reported 94.8K barrels of oil and 4.13M mcf of gas since May 2002, last reporting volume in April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
