Wood County · Quitman field · Shut IN · Vertical
Blalock JA A #7 (API 42-499-31874) is a well in Wood County operated by Wynn-Crosby Operating Ltd., completed September 7, 2011 and listed as shut in on the RRC schedule.
The RRC has issued 2 drilling permits (amended once) between 1996 and 2011, permitted to 6,500 ft.
It was permitted by Goldston Oil Corporation and has since transferred to Wynn-Crosby Operating Ltd. on the wellbore schedule.
Completion filings report 3 formation tops, including Sub-Clarksville, Woodbine, Paluxy.
Its lease has reported 800K barrels of oil and 132K mcf of gas since January 1993, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit.
