Lukoil is currently preparing the drilling location on the Lengupa prospect, which follows up an early find called Medina.

The discovery on Colombia's Condor block was hailed one year ago as a 100-million-barrel field and said to be the first Russian discovery in the Western hemisphere.

Sources close to the operation said that the Medina well fell short of its objective, so the new well is intended to prove up those earlier estimates.
