Koster-Vastar #1 (API 42-361-30707) is a well in Orange County operated by Dominion Expl. & Prod. Inc., completed September 18, 1995.

The RRC has issued one drilling permit, issued May 24, 1995, permitted to 15,000 ft.

It was permitted by Energy Development Corp. and has since transferred to Dominion Expl. & Prod. Inc. on the wellbore schedule.

Completion filings report 5 formation tops, including Frio, Nodosaria, Vicksburg, Yegua.

Its 2 leases have reported 4.66K barrels of oil and 506K mcf of gas since September 1995, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
