Knox County · Katz (Strawn) field · Vertical
Orsborn Alma H. #4 (API 42-275-31950) is a plugged well in Knox County, plugged April 22, 2014, last operated by Apache Corporation.
The RRC has issued one drilling permit (amended once), issued March 5, 1990, permitted to 5,300 ft.
It was permitted by Conoco Inc. and has since transferred to Apache Corporation on the wellbore schedule.
Completion filings report 3 formation tops, including 4800' Strawn, 5100 Strawn, 5100' Strawn.
Its 4 leases have reported 98.1K barrels of oil and 14.3K mcf of gas since January 1993, last reporting in August 2014. The leases carry 10 wells, so these are lease totals, not this well alone.
