Seifert B #4H (API 42-123-33235) is a horizontal well in De Witt County operated by Bpx Operating Company, completed September 27, 2013 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued July 24, 2013, permitted to 13,029 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 3 formation tops, including Anacacho, Austin Chalk, Eagle Ford.

Its lease has reported 1.69M barrels of oil and 5.06M mcf of gas since November 2011, last reporting in July 2026. The lease carries 9 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
