Oil around Neuquen
In the early 20th century there were high hopes of profitable oil extraction in many parts of southern South America. Most of these came to nothing, but in Chilean Tierra del Fuego, around Comodoro Rivadavia and in the Neuquén territory the results were more promising.
After the first world war exploitation of the latter began in earnest, with the biggest concentration around the station of Plaza Huincul along the FCS's Zapala extension west of Neuquén.
