Blair A #1 (API 42-225-31183) is a well in Houston County operated by Trailblazer Energy Resources LLC, completed May 28, 2011 and listed as swr-10-well on the RRC schedule, shut in January 1, 2022.

The RRC has issued one drilling permit (amended once), issued March 23, 2011, permitted to 12,772 ft.

It was permitted by Navidad Resources, LLC and has since transferred to Trailblazer Energy Resources LLC on the wellbore schedule.

Completion filings report 11 formation tops, including Austin Chalk, Sub-Clarksville, Woodbine, Buda.

Its 5 leases have reported 30.6K barrels of oil and 395K mcf of gas since June 2011, with no volume in the three years through April 2026. The leases carry 5 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 7, 2014. 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.
