Haynes #37 (API 42-505-35167) is a well in Zapata County operated by Hilcorp Energy Company, completed July 25, 2005 and listed as swr-10-well on the RRC schedule, shut in March 1, 2019.

The RRC has issued 2 drilling permits between 2004 and 2005, permitted to 11,402 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 3 formation tops, including Queen City, Wilcox, Charco.

Its 2 leases have reported 796 barrels of oil and 1.09M mcf of gas since February 2005, with no volume in the three years through April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.

Well logs

1 log loaded from the RRC's log index, the latest received Jul 23, 2008. 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.
