Riddle E. L. #12
Titus County · Talco field · Vertical
Riddle E. L. #12 (API 42-449-30512) is a well in Titus County operated by Exxon Mobil Corporation, completed July 20, 2009.
The RRC has issued one drilling permit, issued October 22, 1990, permitted to 4,400 ft.
It was permitted by Exxon Corp. and has since transferred to Exxon Mobil Corporation on the wellbore schedule.
Completion filings report 7 formation tops, including Nacatoch, Pecan Gap, Eagle Ford, Woodbine.
Its 2 leases have reported 2.62M barrels of oil and 23 mcf of gas since January 1993, last reporting in July 2026. The leases carry 138 wells, so these are lease totals, not this well alone.
It holds an active disposal or injection permit, with 5.64M barrels injected in the 12 months reported through June 2025.
