Erin #909 (API 42-461-36036) is a well in Upton County operated by Diamondback E&P LLC, completed March 8, 2010 and listed as shut in on the RRC schedule, shut in December 1, 2022.

The RRC has issued one drilling permit, issued August 11, 2008, permitted to 10,188 ft.

It was permitted by Henry Petroleum LP and has since transferred to Diamondback E&P LLC on the wellbore schedule.

Completion filings report 4 formation tops, including T. Clearfork, T. Spraberry, T. Dean, T. Wolfcamp.

Its lease has reported 79.9K barrels of oil and 191K mcf of gas since March 2010, with no volume in the three years through April 2026. The lease carries 2 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 Jan 30, 2013. 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.
