Koster-Vastar #2
Orange County · Red Line (Hartburg Upper) field · Directional
Koster-Vastar #2 (API 42-361-30770) is a well in Orange County operated by Dominion Expl. & Prod. Inc., completed March 19, 2000.
The RRC has issued one drilling permit (amended once), issued December 29, 1999, permitted to 8,300 ft.
It was permitted by Tri-C Resources, Inc. and has since transferred to Dominion Expl. & Prod. Inc. on the wellbore schedule.
Completion filings report one formation top, including Red Line (Hartburg, Upper).
Its 2 leases have reported 62K barrels of oil and 513K mcf of gas since March 2000, last reporting in July 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
