Not one formation; the well must be completed in one of them, and no target formation is stated. The district's wildcat field is also on the permit.

Juana #4 (API 42-505-32218) is a well in Zapata County operated by Hilcorp Energy Company, completed June 17, 1987 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit, issued July 29, 1986, permitted to 9,700 ft.

It was permitted by Transamerican Natural Gas Corp. and has since transferred to Hilcorp Energy Company on the wellbore schedule.

Completion filings report 3 formation tops, including Queen City, Wilcox, Wills Point.

Its 2 leases have reported 27 barrels of oil and 2.04M mcf of gas since the record begins in January 1993, last reporting volume in August 2026. The leases carry 2 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.

Texas locations come from drilling permits, so most older Texas wells have none and are not listed.
