La Perla #77 (API 42-505-32317) is a well in Zapata County operated by Hilcorp Energy Company, completed September 24, 1997 and listed as temp abandoned on the RRC schedule, shut in May 1, 1998.

The RRC has issued 2 drilling permits between 1987 and 1997, permitted to 10,160 ft.

It was permitted by Conoco Inc. 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 16 barrels of oil and 202K mcf of gas since the record begins in January 1993, with no volume in the three years through 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.
