Pettit Walker #1
Hardin County · Sour Lake E. (Yegua #4) field · Vertical
Pettit Walker #1 (API 42-199-31426) is a plugged well in Hardin County, plugged January 23, 2025, last operated by Grayrock Energy II LLC.
The RRC has issued 2 drilling permits (amended once) between 1980 and 1994, permitted to 16,000 ft.
It was permitted by Stillwater Petroleum Company and has since transferred to Grayrock Energy II LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Vicksburg, Jackson, Ledger Sand, Kirby Sand.
Its 3 leases have reported 8.3K barrels of oil and 1.58K mcf of gas since January 1993, last reporting in July 2025. The leases carry 4 wells, so these are lease totals, not this well alone.
