Elkin #1 (API 42-461-31920) is a plugged well in Upton County, plugged September 11, 2014, last operated by Endeavor Energy Resources L.P..

The RRC has issued 2 drilling permits between 1982 and 1991, permitted to 9,000 ft.

It was permitted by Roberts & Hammack, Inc. and has since transferred to Endeavor Energy Resources L.P. on the wellbore schedule.

Completion filings report 3 formation tops, including Clear Fork, Spraberry, Dean.

Its 2 leases have reported 4.11K barrels of oil and 8.44K mcf of gas since January 1993, last reporting in January 2015. The leases carry 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.
