Dielmann #1
Starr County · Samano (Third Massive) field · SWR-10-Well · Vertical
Dielmann #1 (API 42-427-33441) is a well in Starr County operated by Petrovybe Opco LLC, completed August 14, 2002 and listed as swr-10-well on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued January 28, 2002, permitted to 9,519 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 3 leases have reported 67.6K barrels of oil and 5.2M mcf of gas since March 2002, last reporting volume in April 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
