Gregoyle Ltd. a large oil refining company jointly processes purchased hydrocarbons to generate 3 non-saleable intermediate products: ICR8, ING4 and XGE3. Gregoyle's joint processing costs for these intermediate products were $180,000 in August 2017. These intermediate products are further processed separately to produce Crude Oil, Natural Gas Liquids and Natural Gas (measured in liquid equivalents) respectively. The following additional information for August 2017 is available: ICR8/Crude Oil ING4/Natural Gas Liquids XGE3/Natural Gas Seperable costs are splitoff $ 51,500.00 $ Selling price (per barrel) $ Volume sold (barrels) 58.00 $ 15,000.00 30,500.00 $ 45.00 $ 5,000.00 63,000.00 3.90 80,000.00 A federal law has recently been passed that taxes crude oil at 30% of operating income.
