Pembrook 1011 Unit #1H (API 42-383-38388) is a horizontal well in Reagan County operated by Sem Operating Company LLC, completed December 16, 2013 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued July 15, 2013, permitted to 8,024 ft.

It was permitted by Callon Petroleum Operating CO and has since transferred to Sem Operating Company LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Spraberry, Dean, Wolfcamp.

Its lease has reported 1.03M barrels of oil and 4.56M mcf of gas since October 2013, last reporting volume in April 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.

Well logs

1 log loaded from the RRC's log index, the latest received Nov 12, 2014. 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.
