Mueller B #2H (API 42-255-35303) is a horizontal well in Karnes County operated by Bpx Operating Company, completed May 23, 2017 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued February 6, 2017, permitted to 10,475 ft.
It was permitted by Devon Energy Production CO, L.P. and has since transferred to Bpx Operating Company on the wellbore schedule.
Completion filings report 10 formation tops, including Yegua, Queen City, Reklaw, Carrizo.
Its lease has reported 1.1M barrels of oil and 4.25M mcf of gas since May 2017, last reporting volume in April 2026. The lease carries 3 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Apr 24, 2020. Gamma ray. 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.
