El Negro Ranch #6 (API 42-427-32219) is a plugged well in Starr County, plugged July 8, 1997, last operated by Coates Energy Interests Ltd..

The RRC has issued one drilling permit, issued September 30, 1987, permitted to 4,000 ft.

It was permitted by Maddux, Elizabeth H. and has since transferred to Coates Energy Interests Ltd. on the wellbore schedule.

Completion filings report one formation top, including Jackson.

Its lease has reported 10.2K barrels of oil and 179K mcf of gas since January 1993, last reporting in August 1997. The lease carries 5 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.
