Forest Hill /Harris SD/ Unit #13A (API 42-499-31531) is a well in Wood County operated by Gaither Petroleum Corporation, completed March 11, 1987.
The RRC has issued 2 drilling permits between 1987 and 1997, permitted to 5,000 ft.
It was permitted by Exzena Oil Corp. and has since transferred to Gaither Petroleum Corporation on the wellbore schedule.
Completion filings report 6 formation tops, including Nacarosh, Nacatoch, Pecan Gap, Austin Chalk.
Its 2 leases have reported 65.8K barrels of oil and 57 mcf of gas since January 1993, last reporting in July 2026. The leases carry 125 wells, so these are lease totals, not this well alone.
