Black Sea Files is a territorial research on the Caspian oil geography: the world's oldest oil extraction zone. A giant new subterranean pipeline traversing the Caucasus will soon pump Caspian crude to the West. The line connecting the resource fringe with the terminal of the global high-tech oil circulation system, runs through the video like a central thread. However, the trajectory followed by the narrative is by no means a linear one. Circumventing the main players in the region, the video sheds light on a multitude of secondary sceneries. Oil workers, farmers, refugees and prostitutes who live along the pipeline come into profile and contribute to a wider human geography that displaces the singular and powerful signifying practices of oil corporations and oil politicians.
