Earnest W. A. #29-5
Zavala County · Pearsall (Austin Chalk) field · Shut IN · Vertical
Earnest W. A. #29-5 (API 42-507-31886) is a well in Zavala County operated by Cibolo Energy Operating Inc., completed February 1, 1987 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit, issued December 28, 1982, permitted to 7,000 ft.
It was permitted by Ladd Petroleum Corp. and has since transferred to Cibolo Energy Operating Inc. on the wellbore schedule.
Its lease has reported 364K barrels of oil and 726K mcf of gas since January 1993, last reporting in July 2026. The lease carries 15 wells, so these are lease totals, not this well alone.
Operator of record
