Cornell Unit #3080 (API 42-501-35832) is a well in Yoakum County operated by Hilcorp Energy Company, completed October 18, 2011 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued August 3, 2011, permitted to 5,390 ft.
It was permitted by Xto Energy Inc. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 3 formation tops, including Queen, Grayburg, San Andres.
Its lease has reported 20.4M barrels of oil and 35.7M mcf of gas since the record begins in January 1993, last reporting volume in August 2026. The lease carries 268 wells, so these are lease totals, not this well alone.

Texas locations come from drilling permits, so most older Texas wells have none and are not listed.

Well logs
1 log loaded from the RRC's log index, the latest received Sep 27, 2012. 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.
