Tillie Ann A AC #1H (API 42-255-35913) is a horizontal well in Karnes County operated by Bpx Operating Company, completed October 5, 2018 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit, issued September 30, 2018, permitted to 14,000 ft.
It was permitted by Bhp Billiton Pet(Txla OP) CO and has since transferred to Bpx Operating Company on the wellbore schedule.
Completion filings report 10 formation tops, including Yegua, Wilcox, Austin Chalk, Carrizo.
Its lease has reported 696K barrels of oil and 1.59M mcf of gas since March 2018, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
