Sheriff's officials say victims include Noble Energy, Merit Energy and Aka Energy.
Authorities say "large quantities" of oil and gas were released sometime between 4 p.m. Monday and 5 a.m. Tuesday, but it's not known exactly how much was spilled. The oil releases were mostly contained within berms surrounding the tank batteries, although an unknown amount of oil from one spill escaped a berm and is being cleaned up.
Sheriff's officials say there are no known health or safety issues in the affected areas.
