Colombian state-owned oil company Ecopetrol and Canada's Talisman Energy Inc said on Monday they had discovered an estimated 1.3 billion barrels of oil in southeastern Colombia and that about a tenth of it was likely to be recoverable.

The Andean nation also expects to eventually exploit shale oil and gas.
