Ecopetrol has encountered hydrocarbons at the Tinkhana-1 exploratory well in the Western Area (Area Occidental) block in Putumayo basin, Colombia.

The well is part of exploratory work being carried out pursuant to the Western Area production agreement signed with the National Hydrocarbon Agency, in which Ecopetrol holds a 100% interest.

Tinkhana-1 commenced drilling operations on 17 November 2010, reaching a final depth of 6,812ft, the equivalent of more than 2km.

Ecopetrol is currently moving ahead with initial well testing on the Lower Caballos formation, which, with original discovery pressure at a thickness of 16ft, is producing an average oil flow of 140bopd of 25 degree API gravity.

Ecopetrol said that it will continue running tests on the Caballos formation in the weeks to come.
