Janice #13
Ector County · Sallie Ann (Spraberry-Wolfcamp) field · Shut In · Vertical
Janice #13 (API 42-135-39891) is a well in Ector County operated by Diamondback E&P LLC, completed October 9, 2009 and listed as shut in on the RRC schedule, shut in January 1, 2026.
The RRC has issued one drilling permit, issued August 12, 2009, permitted to 10,235 ft.
It was permitted by Devon Energy Production CO, L.P. and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 4 formation tops, including San Andres, Clear Fork, Spraberry, Wolfcamp.
Its lease has reported 639K barrels of oil and 2.84M mcf of gas since December 2007, last reporting volume in April 2026. The lease carries 20 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Jun 15, 2010. 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.
