The Oil Refinery is a large, industrial structure with a complex network of pipes, tanks, and processing units. Its main body is cylindrical, topped with a dome-shaped storage tank, and surrounded by smaller auxiliary tanks and piping. The exterior is made of weathered metal, showing signs of rust and wear, with visible bolts and seams. The refinery features a control panel with buttons and gauges, and emits a faint glow from its operational lights. The overall design is functional yet detailed, with a focus on industrial realism.
