Laurel Mineral Estate #15
Zapata County · Charco (9900) field · SWR-10-Well · Directional
Laurel Mineral Estate #15 (API 42-505-35536) is a well in Zapata County operated by Hilcorp Energy Company, completed August 8, 2007 and listed as swr-10-well on the RRC schedule, shut in February 1, 2014.
The RRC has issued one drilling permit, issued April 19, 2006, permitted to 11,864 ft.
It was permitted by Conocophillips Company and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 3 formation tops, including Perdido, Wilcox, Wills Point.
Its 2 leases have reported 4.18K barrels of oil and 620K mcf of gas since December 2006, with no volume in the three years through 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 Jul 23, 2009. 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.

"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.
