King County · Katz field · Vertical
Howell G. L. #10 (API 42-269-31904) is a disposal or injection well in King County operated by Cholla Petroleum Inc. under an active UIC permit.
The RRC has issued one drilling permit, issued April 13, 1989, permitted to 5,300 ft.
It was permitted by Conoco Inc. and has since transferred to Cholla Petroleum Inc. on the wellbore schedule.
Completion filings report 4 formation tops, including Coleman Junction, Strawn, 4800' Strawn, 5100' Strawn.
Its 2 leases have reported 379K barrels of oil and 12K mcf of gas since January 1993, last reporting in July 2026. The leases carry 25 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 233 barrels injected in the 12 months reported through September 2025.
