Gramm Unit #2H (API 42-255-32145) is a horizontal well in Karnes County operated by Devon Energy Production CO L.P., completed September 27, 2013 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued October 7, 2011, permitted to 10,070 ft.

It was permitted by Plains Exploration & Prod. CO. and has since transferred to Devon Energy Production CO L.P. on the wellbore schedule.

Completion filings report 3 formation tops, including Anacacho, Austin Chalk, Eagle Ford.

Its lease has reported 1.1M barrels of oil and 2.15M mcf of gas since December 2011, last reporting volume in April 2026. The lease carries 8 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 Feb 17, 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.
