Wise County · Alvord (Caddo Conglomerate) field · Producing · Vertical
Deaver (Caddo Congl) Unit #5-1W (API 42-497-31501) is a well in Wise County operated by Schalk Oil Company Inc., completed October 4, 1979 and listed as producing on the RRC schedule, shut in December 1, 2025.
The RRC has issued one drilling permit, issued May 31, 1979, permitted to 5,950 ft.
It was permitted by Mitchell Energy Corporation and has since transferred to Schalk Oil Company Inc. on the wellbore schedule.
Completion filings report 4 formation tops, including Bryson, Caddo, T/Caddo Lime, T/Caddo Congl..
Its lease has reported 251K barrels of oil and 586K mcf of gas since the record begins in January 1993, last reporting volume in April 2026. The lease carries 31 wells, so these are lease totals, not this well alone.

Surface location
No coordinates on the permit record yet. The RRC's GIS record usually lands within days of issuance; historical master-file permits never carry one.

Every well with a location on file around this well, in any state, nearest first.
Texas locations come from drilling permits, so most older Texas wells have none and are not listed.
