Traylor Maude B. #28 (API 42-057-31527) is a plugged well in Calhoun County, plugged July 23, 2015, last operated by Silverbrook Operating LLC.

The RRC has issued 4 drilling permits (amended twice) between 1993 and 2003, permitted to 15,000 ft.

It was permitted by Gruy Petroleum Management CO. and has since transferred to Silverbrook Operating LLC on the wellbore schedule.

Completion filings report 4 formation tops, including Miocene (undifferentiated), Freda, Melbourne, Frio.

Its 5 leases have reported 283K barrels of oil and 692K mcf of gas since January 1993, last reporting in July 2026. The leases carry 8 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.
