Gwosdz A #11H (API 42-123-34143) is a horizontal well in De Witt County operated by Bpx Operating Company, completed January 12, 2017 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued July 16, 2015, 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 13 formation tops, including Yegua, Cook Mountain, Sparta, Wilcox.
Its lease has reported 2.77M barrels of oil and 9.5M mcf of gas since August 2011, last reporting in July 2026. The lease carries 13 wells, so these are lease totals, not this well alone.
