“When the relationship turned sour in the 1990s, Exxon-Mobil terminated the lease and plugged the wells,” states Patterson’s report. “As per state rules, Exxon filed paperwork with the Railroad Commission outlining its well-plugging procedures and filed sworn affidavits as to the final condition of the wells. The O’Connor family soon learned those reports to the Railroad Commission were fraudulent.

“When an independent producer, Emerald Oil, attempted to capitalize on new legislative incentives to reopen abandoned wells, they found the old Exxon-Mobil wells hadn’t been plugged but sabotaged — filled with junk, cut well casings, contaminated oil tank sludge and even explosives. Many of the wells were left unrecoverable.”
