Charlotte Unit #43H (API 42-255-36457) is a horizontal well in Karnes County operated by Devon Energy Production CO L.P., completed August 29, 2019 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued May 14, 2019, permitted to 11,050 ft.

It was permitted by Encana Oil & Gas(USA) Inc. and has since transferred to Devon Energy Production CO L.P. on the wellbore schedule.

Completion filings report 10 formation tops, including Frio, Queen City, Reklaw, Carrizo.

Its lease has reported 1.08M barrels of oil and 1.81M mcf of gas since February 2017, last reporting in July 2026. The lease carries 4 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.
