Williams C.W-C #4 (API 42-371-33055) is a well in Pecos County operated by Riata Energy Inc., completed June 27, 1980.

The RRC has issued one drilling permit, issued April 11, 1980, permitted to 3,000 ft.

It was permitted by Lawrence, C. F. & Assoc. Inc. and has since transferred to Riata Energy Inc. on the wellbore schedule.

Its 2 leases have reported 24.9K barrels of oil and 12.8K mcf of gas since January 1993, last reporting in July 2026. The leases carry 15 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.
