WELL · 42-175-32530 · DISTRICT 2
Blackburn #46
Goliad County · Berclair (Vicksburg) field · Shut IN · Vertical
Blackburn #46 (API 42-175-32530) is a well in Goliad County operated by Terrafina Energy LLC, completed January 11, 1991 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued August 10, 1990, permitted to 3,600 ft.
It was permitted by Fina Oil & Chemical Company and has since transferred to Terrafina Energy LLC on the wellbore schedule.
Completion filings report one formation top, including Vicksburg.
Its lease has reported 300K barrels of oil and 147K mcf of gas since January 1993, last reporting in July 2026. The lease carries 18 wells, so these are lease totals, not this well alone.
