Houston County · Fort Trinidad East (Buda) field · Vertical
Tolbert #1 (API 42-225-31327) is a plugged well in Houston County, plugged November 14, 2022, last operated by Trailblazer Energy Resources LLC.
The RRC has issued one drilling permit (amended once), issued May 9, 2014, permitted to 12,500 ft.
It was permitted by Sem Operating Company LLC and has since transferred to Trailblazer Energy Resources LLC on the wellbore schedule.
Completion filings report 8 formation tops, including Sub-Clarksville, Woodbine, Buda, Edwards.
Its 3 leases have reported 13K barrels of oil and 92.3K mcf of gas since August 2014, with no volume in the three years through April 2026. The leases carry 3 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received May 22, 2017. Gamma ray. 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.
