Juan David Mogollon, owner of the bar "Estadero Rubiales", speaks during an interview in the central square of Puerto Gaitan town in Meta, eastern Colombia, in this photo taken on February 12, 2015. Colombia is not a major producer - it has less than seven-years of reserves - but security gains against Marxist rebel groups opened up areas that were previously too dangerous to operate in, and drove a decade-long oil boom. That drew $34.6 billion of foreign direct investment into the sector in the last 10 years, up from just $3.1 billion in the previous decade, and it helped fuel fast growth in Latin America's 4th largest economy.
