Lambshead F-1 #4S
Throckmorton County · Paint Canyon (Cook) field · Vertical
Lambshead F-1 #4S (API 42-447-35557) is a plugged well in Throckmorton County, plugged April 21, 2021, last operated by Daylight Petroleum LLC.
The RRC has issued one drilling permit (amended once), issued July 10, 1995, permitted to 2,000 ft.
It was permitted by L.C.S. Production Company and has since transferred to Daylight Petroleum LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Tannehill, Bluff Creek, Cook.
Its lease has reported 98.5K barrels of oil and 6 mcf of gas since June 1995, with no volume in the three years through April 2026. The lease carries 10 wells, so these are lease totals, not this well alone.
Operator of record
Permitted by L.C.S. Production Company; the EWA schedule now lists a different operator.
