University -13- #6 (API 42-317-35394) is a well in Martin County operated by Diamondback E&P LLC, completed December 10, 2008 and listed as shut in on the RRC schedule, shut in April 1, 2014.

The RRC has issued one drilling permit (amended once), issued August 15, 2008, permitted to 10,990 ft.

It was permitted by Wagner Oil Company and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Spraberry, Dean, Wolfcamp.

Its lease has reported 216K barrels of oil and 317K mcf of gas since October 2008, last reporting volume in August 2025. The lease carries 4 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 Nov 1, 2011. Density, 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.
