Atascosa County · Somerset field · Vertical
Bonanza #7 (API 42-013-33108) is a plugged well in Atascosa County, plugged December 21, 2017, last operated by Drachen Oil Company.
The RRC has issued one drilling permit, issued December 31, 1984, permitted to 1,600 ft.
It was permitted by Cromoco, Inc. and has since transferred to Drachen Oil Company on the wellbore schedule.
Completion filings report one formation top, including Olmos.
Its lease has reported 16.4K barrels of oil and 26 mcf of gas since January 1993, last reporting in July 2026. The lease carries 13 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by Cromoco, Inc.; the EWA schedule now lists a different operator.
