Halff 2b #2 (API 42-461-39356) is a plugged well in Upton County, plugged April 13, 2026, last operated by Pioneer Natural Res. USA Inc..

The RRC has issued one drilling permit, issued April 25, 2014, permitted to 11,800 ft.

It was permitted by Parsley Energy Operations, LLC and has since transferred to Pioneer Natural Res. USA Inc. on the wellbore schedule.

Completion filings report 10 formation tops, including San Andres, Spraberry, Wolfcamp, Strawn.

Its lease has reported 71.7K barrels of oil and 202K mcf of gas since December 2013, with no volume in the three years through April 2026. The lease carries 2 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 Jun 12, 2017. Neutron. 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.
