Petroleum – its extraction, refining, transformation, and consumption – has shaped our built environment in visible and invisible interconnected ways around the world over the last 150 years. Industrial structures, buildings, monuments, urban forms, and infrastructure stand as material witnesses to the ubiquity and power of petroleum.
