Even though 85% of world crude production was still coming from Pennsylvania wells in the 1880s, overseas drilling in Russia and Asia began to reach the world market. Robert Nobel had established his own refining enterprise in the abundant and cheaper Russian oil fields, including the region's first pipeline and the world's first oil tanker. The Paris Rothschilds jumped into the fray providing financing. Additional fields were discovered in Burma and Java. Even more critical, the invention of the light bulb gradually began to erode the dominance of kerosene for illumination. But Standard Oil adapted, developing its own European presence, expanding into natural gas production in the U.S., then into gasoline for automobiles, which until then had been considered a waste product.
