Mathews Strawn #1 (API 42-451-30834) is a plugged well in Tom Green County, plugged April 28, 2008, last operated by Arch Oil & Gas LLC.

The RRC has issued 2 drilling permits between 1981 and 2009, permitted to 7,000 ft.

It was permitted by Silver Oil & Gas Inc. and has since transferred to Arch Oil & Gas LLC on the wellbore schedule.

Completion filings report 7 formation tops, including San Andres, Base Wlcmp, Wolfcamp, Canyon.

Its 4 leases have reported 133K barrels of oil and 581K mcf of gas since January 1993, last reporting in July 2026. The leases carry 107 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.
