Mayer B #1H (API 42-255-32416) is a horizontal well in Karnes County operated by Bpx Operating Company, completed August 28, 2012 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued April 4, 2012, permitted to 10,999 ft.
It was permitted by Petrohawk Operating Company 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 1.34M barrels of oil and 1.51M mcf of gas since August 2012, last reporting volume in April 2026. The lease carries 5 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Jun 23, 2015. Resistivity. These are the logs loaded into Petrora from the Railroad Commission's inventories, not necessarily every log run on the well. The RRC holds the files; each opens from its log search for the well. The kind is the RRC's description of the log; the interval is the one filed for it.

"Spans" is by this well's own filed formation tops: a formation runs from its top to the next deeper top filed, and the deepest runs to the bottom of the log. Depths are measured along the wellbore, so on a horizontal the lateral counts in the formation it was landed in.
