Midland County · Spraberry (Trend Area) field · Vertical
Cassidy -A- #2 (API 42-329-31861) is a plugged well in Midland County, plugged October 30, 2025, last operated by Diamondback E&P LLC.
The RRC has issued one drilling permit, issued June 30, 1987, permitted to 9,350 ft.
It was permitted by Parker & Parsley Petroleum CO. and has since transferred to Diamondback E&P LLC on the wellbore schedule.
Completion filings report 8 formation tops, including T Upper Spraberry, T. Upper Spraberry, T Lower Spraberry, T. Lower Spraberry.
Its lease has reported 62.7K barrels of oil and 274K mcf of gas since January 1993, with no volume in the three years through April 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
