The oil industry in Poland began with the first oil well in the world, at Bóbrka Field in 1853, followed by the first refinery in 1854. Poland was the third most productive region in the world in 1900. It now has only a small, mostly state-owned component, with production from its Permian Basin in the west, small and very old fields in the Carpathians in the south, and offshore in the Baltic Sea. For natural gas the country is almost completely dependent on legacy pipelines from the former Soviet Union.
