EC Ecopetrol SA

MOSCOW--OAO Lukoil Holdings (LKOH.RS), Russia's second-largest oil producer, said Wednesday it was selling its stake in the Condor exploration and development project in Colombia in order to optimize its portfolio of assets.

Omega Energy Colombia will buy Lukoil's stake, Lukoil said in a statement, without giving the price.

Lukoil's international arm had entered the project in 2002 with a 70% stake. Ecopetrol (EC) holds the other 30%.

The block covers some 3.1 square kilometers and is located 70 kilometers southeast of Bogota.
