Eastham State Prison Farm #0402 (API 42-225-31311) is a well in Houston County operated by Trailblazer Energy Resources LLC, completed May 3, 2014 and listed as swr-10-well on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued February 19, 2014, permitted to 12,236 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 9 formation tops, including Sub-Clarksville, Woodbine, Buda, Georgetown.

Its 3 leases have reported 93K barrels of oil and 587K mcf of gas since May 2014, last reporting volume in April 2026. The leases carry 3 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 Mar 24, 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.
