Ecopetrol said it has launched a bidding process to offer oil and gas companies its stake and interests in 20 production assets in a number of regions in Colombia.
The company said the move is part of its strategy up to 2020, based on creating more efficient operation of assets.
The locations include Catatumbo, the Magdalena Middle and Upper Valley, Llanos and Putumayo.
A spokesman said: “The business opportunities offered have development potential in primary recovery and improved recovery. The fields are located near logistical facilities, which are an added attraction for small- and medium-sized oil and gas companies.
“The process, which was presented to industry representatives, is a public bidding process addressed to national and international companies that would like to strengthen their position in Colombia or that seek to expand their operations in the country.”
