Survey of Surface Geoquemistry and Microbiological analysis in Guajira Basin, Colombia

March, 2014

In the framework of exploration of Guajira basin in north of Colombia, Ecopetrol picked up 400 soils

samples in a frontier onshore area, these samples were analized using Head Space Gas (HSG) and MET

techniques. The work was developed by EBT Inc’s.

The results let us to take decisions about interesting areas for oil and gas exploration, these anomalies

highlight hydrocarbon presence in surface, therefore it is possible that a petroleum system is working at

the area.

In our concept, we recommended the technique because is not expensive and you can have reliable

data in a short time.
