Jeffs 3a #4 (API 42-383-37898) is a well in Reagan County operated by Civitas Permian Operating LLC, completed April 27, 2013 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended twice), issued July 10, 2012, permitted to 10,305 ft.
It was permitted by Apache Corporation and has since transferred to Civitas Permian Operating LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Spraberry, Dean, Wolfcamp.
Its lease has reported 162K barrels of oil and 1.17M mcf of gas since February 2012, last reporting volume in November 2025. The lease carries 4 wells, so these are lease totals, not this well alone.

Completion filings
W-2 and G-1 reports on record in the RRC wellbore file, newest first. The suffix identifies the wellbore or completion event. The record date is the RRC's own date on the record, not the day the report was filed: 462,034 of the state's filings carry 1984-01-12. About these reports →

Well logs
1 log loaded from the RRC's log index, the latest received May 9, 2016. 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.
