Martin County · Spraberry (Trend Area) field · Producing · Vertical
Holt Ranch #35 (API 42-317-39071) is a well in Martin County operated by Ovintiv USA Inc., completed February 20, 2014 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued December 3, 2013, permitted to 11,940 ft.
It was permitted by Piedra Operating, LLC and has since transferred to Ovintiv USA Inc. on the wellbore schedule.
Completion filings report 10 formation tops, including Cisco, Devonian, Fusselman, Grayburg.
Its lease has reported 2.62M barrels of oil and 8.4M mcf of gas since April 2011, last reporting volume in April 2026. The lease carries 45 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Feb 15, 2017. 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.
