Oversupply of Sand Hurting Wisconsin Mining Operations

A nationwide oversupply of the sand used in oil fracking processes is hitting Wisconsin mines hard.  The company which owns Superior Silica Sands has entered into a debt restructuring deal with its lenders.  Emerge Energy Services could file for bankruptcy if a settlement isn’t reached.  One consultant predicts up to three-fourths of Wisconsin sand mines might have to cease operations.  Oil and gas companies have been building more mines near their oil fields in Oklahoma and Texas.
