Schneider National will add 500 driving jobs to support the fleet’s expansion into the country’s booming oil-shale sector.

Schneider said it is offering new service to companies in the hydraulic fracturing, or "fracking," industry, according to the Milwaukee Journal Sentinel.

Schneider wants to fill 500 permanent, full-time driving jobs in seven states — Wyoming, Texas, Oklahoma, New Mexico, Arkansas, Louisiana and New York — by year's end. Drivers can earn as much as $60,000 a year, the company said, and
relocation assistance may be available for some drivers.

In the fracking process, drillers inject water, sand and chemicals into wells under great pressure to create cracks in surrounding rocks. The process releases oil or natural gas that otherwise couldn't be tapped efficiently.

Drivers will be trained to carry sand and cement to the oil fields and haul away crude oil and condensate, as well as move equipment in and around the work sites.
