FACTBOX-Recent investments in Colombia's oil sector

Dec 9 (Reuters) - Colombia says foreign investment in its oil sector will surpass $3.5 billion next year as the Andean country enjoys a “miniboom” that has made it Latin America’s No. 4 oil producer. with output of 700,000 barrels per day.

Colombia’s 2009 oil production is forecast at 700,000 barrels per day, up from 588,000 bpd last year, according to government figures.

Foreign investment in Colombia's oil industry in 2009 was $3.4 billion, led by Canadian companies, such as Pacific Rubiales PRE.TO, which is now producing 100,000 bpd, according to National Hydrocarbons Agency.

Investment has increased in Colombia as security has improved since President Alvaro Uribe came to office in 2002 and sent troops to retake areas once controlled by armed groups caught up in the country’s long guerrilla war. Kidnappings, bombings and attacks have ebbed dramatically.
