Since the discovery of oil at Spindletop in 1901, the Port of Houston has been instrumental in the city of Houston's development as a center of the international oil trade. It currently is home to a $15 billion petrochemical complex, the largest in the nation and second largest in the world. Other industries including asphalt and cement plants, bulk liquid storage, ship repair, fuel bunkering, recycling, cargo handling and warehousing help keep the port consistently ranked 1st in the United States in foreign waterborne tonnage; 1st in U.S. imports; 1st in U.S. export tonnage and 2nd in the U.S. in total tonnage. Ship channel-related businesses contribute 1,026,820 jobs throughout Texas generating more than $178.5 billion in statewide economic impact and more than $4.5 billion in state and local tax revenues. MaRS in collaboration with Woreman Brand Agency chose to depict the importance of the oil trade to Houston’s economy vitality in the form of an oil pipeline graphic. The infinite pipe pattern acknowledges our insatiable appetite for this critical natural resource while the verticality references the fact that oil is largely obtained from a process of extraction.
