Laurel O. M. Estate #5 (API 42-505-35277) is a well in Zapata County operated by Hilcorp Energy Company, completed September 10, 2008 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued May 5, 2005, permitted to 12,200 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 2 leases have reported 966 barrels of oil and 760K mcf of gas since June 2005, 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 Sep 26, 2006. Density, Gamma ray, 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.

"Spans" is by this well's own filed formation tops: a formation runs from its top to the next deeper top filed, and the deepest runs to the bottom of the log. Depths are measured along the wellbore, so on a horizontal the lateral counts in the formation it was landed in.
