Roberts County · Alpar-Lips (Tonkawa) field · Vertical
Courson Ranch 136 #4C (API 42-393-31153) is a plugged well in Roberts County, plugged July 13, 2017, last operated by Latigo Petroleum LLC.
The RRC has issued one drilling permit, issued September 5, 1990, permitted to 7,000 ft.
It was permitted by Alpar Resources, Inc. and has since transferred to Latigo Petroleum LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Brn Dolo, Douglas, Tonkawa, Cleveland.
Its 2 leases have reported 1.89K barrels of oil and 454K mcf of gas since January 1993, with no volume in the three years through April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.
