Coseka/Saxon Davidson #4 (API 42-461-32071) is a plugged well in Upton County, plugged March 15, 2011, last operated by Chevron Midcontinent L.P..

The RRC has issued one drilling permit, issued September 29, 1983, permitted to 9,250 ft.

It was permitted by Coseka Resources (U.S.A.) Ltd. and has since transferred to Chevron Midcontinent L.P. on the wellbore schedule.

Completion filings report 3 formation tops, including U. Spraberry, L. Spraberry, Dean.

Its lease has reported 39.9K barrels of oil and 171K mcf of gas since January 1993, last reporting in February 2012. 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.
