Archer County · Archer County Regular field · Injection · Vertical
Oldham #100 (API 42-009-37259) is a well in Archer County operated by Chek Oil CO. LLC, completed August 23, 1985 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued July 5, 1983, permitted to 1,400 ft.
It was permitted by Bytex Oil Company and has since transferred to Chek Oil CO. LLC on the wellbore schedule.
Completion filings report one formation top, including Gunsite Sand.
Its lease has reported 74.2K barrels of oil and 46 mcf of gas since January 1993, last reporting in July 2026. The lease carries 5 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 17.8K barrels injected in the 12 months reported through December 2025.
