Wheeler Karen #4 (API 42-311-33983) is a well in Mcmullen County operated by Gtg Operating LLC, completed December 4, 2007 and listed as shut in on the RRC schedule, shut in April 1, 2019.

The RRC has issued one drilling permit, issued August 15, 2007, permitted to 10,126 ft.

It was permitted by Welhausen Operating Company, LP and has since transferred to Gtg Operating LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Queen City, Carrizo, Olmos.

Its lease has reported 149K barrels of oil and 283K mcf of gas since December 2007, last reporting in July 2026. The lease carries 6 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.
