Slaughter Consolidated #421
Hockley County · Tstar (Abo) field · Producing · Horizontal · Directional
Slaughter Consolidated #421 (API 42-219-36687) is a horizontal well in Hockley County operated by Hilcorp Energy Company, completed August 23, 2007 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits between 2002 and 2007, permitted to 8,170 ft.
It was permitted by Oxy USA Wtp LP and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 9 formation tops, including Yates, Seven Rivers, Queen, Grayburg.
Its lease has reported 19M barrels of oil and 17M mcf of gas since January 1999, last reporting volume in April 2026. The lease carries 106 wells, so these are lease totals, not this well alone.

Completion filings
W-2 and G-1 reports on record in the RRC wellbore file, newest first. The suffix identifies the wellbore or completion event. The record date is the RRC's own date on the record, not the day the report was filed: 462,034 of the state's filings carry 1984-01-12. About these reports →

Well logs
1 log loaded from the RRC's log index, the latest received Apr 23, 2009. Cased hole. 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.
