Zapata County · Jennings Ranch (Lobo Cons.) field · Producing · Directional
Las Ovejas-State #1 (API 42-505-35212) is a well in Zapata County operated by Hilcorp Energy Company, completed April 3, 2006 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended twice), issued February 9, 2005, permitted to 12,160 ft.
It was permitted by Chesapeake Operating, Inc. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 2 formation tops, including Perdido, Lobo.
Its 3 leases have reported 5.72K barrels of oil and 4.44M mcf of gas since March 2005, last reporting volume in April 2026. The leases carry 3 wells, so these are lease totals, not this well alone.
