Benavides Trust #8
Zapata County · Hundido (9300) field · SWR-10-Well · Vertical
Benavides Trust #8 (API 42-505-34901) is a well in Zapata County operated by Merit Energy Company, completed April 6, 2004 and listed as swr-10-well on the RRC schedule, shut in December 1, 2009.
The RRC has issued one drilling permit (amended once), issued January 6, 2004, permitted to 11,200 ft.
It was permitted by Pogo Producing CO. and has since transferred to Merit Energy Company on the wellbore schedule.
Completion filings report 4 formation tops, including Top Of 9300, Lobo Unconformity, Lobo 6, Wills Point.
Its 2 leases have reported 15 barrels of oil and 345K mcf of gas since March 2004, 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 Jun 7, 2007. 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.
