Sebastian *19-30A #4301H
Upton County · Spraberry (Trend Area) R 40 Exc field · Shut In · Horizontal
Sebastian *19-30a #4301H (API 42-461-40650) is a horizontal well in Upton County operated by Pioneer Natural Res. USA Inc., completed June 7, 2018 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued August 17, 2017, permitted to 9,421 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, Clear Fork, Spraberry, Dean.
Its lease has reported 828K barrels of oil and 3.49M mcf of gas since June 2018, 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, 1 of it with a digital LAS file, the latest received Apr 5, 2021. 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.
