Crockett County · Spraberry (Trend Area) field · Observation · Vertical
Univkeisha #7191 (API 42-105-41311) is a well in Crockett County operated by Zarvona Energy LLC, completed December 15, 2011 and listed as observation on the RRC schedule, shut in February 1, 2026.
The RRC has issued one drilling permit (amended 3 times), issued August 5, 2011, permitted to 8,959 ft.
It was permitted by Conocophillips Company and has since transferred to Zarvona Energy LLC on the wellbore schedule.
Completion filings report 2 formation tops, including Spraberry, Wolfacamp.
Its lease has reported 880K barrels of oil and 2.2M mcf of gas since December 2011, last reporting volume in April 2026. The lease carries 18 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Nov 10, 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.
