ESSEX OIL & GAS CORPORATION
Essex is an industry "Petroleum Jobber", a company that purchases quantities of refined fuel from refining companies (e.g., BP, Shell, Exxon, Conoco) at bulk wholesale rates for sale to retailers (e.g., gasoline stations, States, Industry) directly to the users of those products (e.g., home heating oil to homeowners, lubricating oils to industrial operations or repair shops, jet fuel to FBOs, etc). In essence, the jobber acts as the "middleman" between the company that refines the petroleum products and those that use them or market them at retail prices. The jobber often owns the gasoline being sold, and the station it is being sold to.
Over 44.3% of all gasoline in the U.S. is sold through jobbers. Approximately the same percentage was sold through integrated oil company-owned and operated stores or franchise arrangements.
