What was discovered

The Barroso 2 well at La Rosa on Lake Maracaibo gushed uncontrolled for nine days at about 100,000 barrels a day. It made Venezuela a major oil exporter and attracted American companies.

Venezuela's first commercial well was Zumaque I (Mene Grande, 1914), but the Barroso II blowout revealed the country's potential.

What it led to

  • the Lake Maracaibo oil boom
  • Venezuela as the world's second producer in the 1920s and 1930s
  • fiscal dependence on oil and the 'petrostate'
