Oil and gas logistics comprises all the supply chain activities for refined oil and gas, starting from refineries to point-of-sale (POS) outlets, such as fuel (filling) stations. Oil and gas products are transported to fuel stations primarily using two modes of transportation, namely railroad and tanker trucks. Oil and gas logistics covers the transportation of heavy-lift structures and logistics support for offshore and onshore assets used in operations to extract crude oil and natural gas. Oil and gas transportation covers all the different stages in the oil and gas industry, from upstream to downstream.
