Guadalupe County · Luling-Branyon field · Vertical
A.J. & J.M. Mckean #4 (API 42-187-03063) is a well in Guadalupe County operated by Meridian Exploration CO., completed December 8, 1965.
The RRC has issued one drilling permit, issued October 21, 1982, permitted to 2,042 ft.
It was permitted by Tri-County Operating Company and has since transferred to Meridian Exploration CO. on the wellbore schedule.
Its lease has reported 3.47K barrels of oil and 3.62K mcf of gas since January 1993, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Tri-County Operating Company; the EWA schedule now lists a different operator.
