The Oil Refinery is a large, industrial structure with a complex network of pipes, tanks, and processing units. It features a metallic framework with a combination of smooth and rusted surfaces, indicating heavy use and exposure to the elements. The main body is cylindrical with multiple levels, each housing different refining components, and is topped with a series of chimneys emitting smoke. The color scheme is predominantly industrial greys and browns, with occasional bright yellow or red warning labels and hazard stripes for safety markings.
