Zapata County · Roleta (Wilcox Consolidated) field · SWR-10-Well · Vertical
Don Hilario A #4 (API 42-505-36458) is a well in Zapata County operated by Hilcorp Energy Company, completed October 20, 2009 and listed as swr-10-well on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued August 27, 2009, permitted to 10,410 ft.
It was permitted by Ricochet Energy, Inc. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Its 2 leases have reported 2.1K barrels of oil and 1.96M mcf of gas since October 2009, last reporting volume in April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Apr 13, 2015. Density, Neutron, Resistivity. These are the logs loaded into Petrora from the Railroad Commission's inventories, not necessarily every log run on the well. The RRC holds the files; each opens from its log search for the well. The kind is the RRC's description of the log; the interval is the one filed for it.
