Zapata County · Haynes (Middle Wilcox Cons.) field · Producing · Directional
Haynes #29 (API 42-505-34799) is a well in Zapata County operated by Hilcorp Energy Company, completed March 28, 2006 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits (amended once) between 2003 and 2006, permitted to 14,560 ft.
It was permitted by Devon Energy Production CO, L.P. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 6 formation tops, including Queen City, Wilcox, Top Charco, Lobo Unconfority.
Its 3 leases have reported 1.16K barrels of oil and 3.14M mcf of gas since November 2003, last reporting volume in April 2026. The leases carry 3 wells, so these are lease totals, not this well alone.

Well logs
2 logs loaded from the RRC's log index, the latest received Apr 26, 2007. 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.
