What was the first company to drill for oil in Venezuela?
History of the Venezuelan oil industry
Cabimas still plays an important role in production from the nation's largest oil fields, which are located around and beneath Lake Maracaibo. Other fields are increasing in importance, mainly in eastern Venezuela.[11] About twenty years after the completion of the first oil-producing well Venezuela had become the largest oil exporter in the world and, after the United States, the second largest oil producer. Exports of oil boomed  between 1920 and 1935.[12] By the end of the 1930s, Venezuela had become the third-leading oil producer in the world, behind the United States and the Soviet Union, as well as the leading exporter.[13]
