Kwb Unit #1 (API 42-451-30964) is a well in Tom Green County operated by Sonoran Energy Inc., completed February 1, 1999.

The RRC has issued one drilling permit, issued April 28, 1982, permitted to 7,500 ft.

It was permitted by Mitchell Energy Corporation and has since transferred to Sonoran Energy Inc. on the wellbore schedule.

Completion filings report 5 formation tops, including Coleman Junction, T/Canyon, T/Canyon Lime, T/Strawn.

Its 4 leases have reported 113K barrels of oil and 620K mcf of gas since January 1993, last reporting in July 2026. The leases carry 106 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.
