Colombia is not a major producer -- it has less than seven years of reserves -- but security gains against rebel groups opened up areas that were previously too dangerous to operate in, and drove a decade-long oil boom. That drew US$34.6 billion of foreign direct investment into the sector in the last 10 years, up from just US$3.1 billion in the previous decade, and it helped fuel fast growth in Latin America’s fourth largest economy.
