Simpson V. P. #21 (API 42-133-37288) is a well in Eastland County operated by King Energy Resources, completed October 30, 1988 and listed as injection on the RRC schedule.
The RRC has issued one drilling permit, issued July 25, 1988, permitted to 1,200 ft.
It was permitted by Mercury Exploration CO. and has since transferred to King Energy Resources on the wellbore schedule.
Completion filings report 2 formation tops, including Cross Cut, Adams Branch.
Its lease has reported 49.1K barrels of oil and 21 mcf of gas since January 1993, last reporting in July 2026. The lease carries 22 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 1.3K barrels injected in the 12 months reported through April 2026.
