The growth of Colombia's oil and gas industries is attention-grabbing by any standards. As recently as 2007 the country was producing around 500 million barrels of oil equivalent per day (boed) the first half of last year that figure topped a billion. Though there is an increasing number of outside players involved, the lion's share of this production boom has been achieved by the largely government-owned petroleum business Ecopetrol, today one of the 25 largest petroleum companies in the world.
