As of December 31, 2022, our asset portfolio consisted of: •our refined products segment, comprised of our approximately 9,800-mile refined petroleum products pipeline system with 54 terminals and two marine storage terminals (one of which is owned through a joint venture); and •our crude oil segment, comprised of approximately 2,200 miles of crude oil pipelines, a condensate splitter and 39 million barrels of aggregate storage capacity, of which approximately 29 million barrels are used for contract storage. Approximately 1,000 miles of these pipelines, the condensate splitter and 31 million barrels of this storage capacity (including 25 million barrels used for contract storage) are wholly-owned, with the remainder owned through joint ventures. Description of Products The following terms are commonly used in our industry to describe products that we transport, store, distribute or otherwise handle through our petroleum pipelines and terminals: •refined products are the output from crude oil refineries that are primarily used as fuels by consumers. Refined products include gasoline, diesel fuel, aviation fuel, kerosene and heating oil. Diesel fuel, kerosene and heating oil are also referred to as distillates; •transmix is a mixture that forms when different refined products are transported in pipelines. Transmix is fractionated and blended into usable refined products; •LPGs are liquids produced as by-products of the crude oil refining process and in connection with natural gas production. LPGs include gas liquids such as butane, natural gasoline and propane; •crude oil, which includes condensate, is a naturally occurring unrefined petroleum product recovered from underground that is used as feedstock by refineries, splitters and petrochemical facilities. We use the term petroleum products to describe any, or a combination, of the above-noted products. In addition, we handle, store and distribute renewable fuels, such as ethanol and biodiesel.
