CountryMark is an agricultural cooperative firm, headquartered in Indianapolis, that operates in the United States crude oil and oil refinery businesses. Its chief asset is an oil refinery in Mount Vernon, Indiana, which is fitted to process 34,000 barrels-per-day of crude from the Illinois Basin, a series of small oilfields in southeastern Illinois, southwestern Indiana, and western Kentucky. In addition to refining oil and retailing oil products, its fleet of trucks gathers crude oil from Illinois Basin producers and, in 2008, acquired the Evansville-based company Core Minerals and entered the business of searching for and directly producing crude oil. CountryMark also owns a 238-mile-long (383 km) finished product pipeline, running from the refinery in Mount Vernon to Peru, Indiana. CountryMark has terminals at the refinery, along the pipeline at Switz City and Jolietville, Indiana, and at the terminus of the pipeline at Peru.2
