Fully developed in our partner laboratories. DNA Geochemical identification technique has minimal environmental and social impact due to the ease of sample collection in the project area. It is the most innovative surface geochemistry technique recently developed thanks to advances in genetics.
DNA Geochemical technique is based on the Quantification Polymerase Chain Reaction (qPCR) process. It is the use of markers specifically designed by our biologists to identify more than 100 types of microorganisms that feed on C2 – C8. With this method all the bacteria present in the soil is determined. The amount of information obtained is increased by extending the study to all species.
This technique is supported by the theory of vertical microseepage of hydrocarbon gases trapped in reservoirs. The released gases change the composition of the different layers of the subsoil during its migration up to the surface.
Samples analyzed do not require incubation or dilution processes reducing delivery times of results. The technique works in all ecosystems since the analysis is done over present DNA and not over living beings. No need to generate cultures of bacteria in the laboratory reducing human error.
DNA technique allows to determine the location of hydrocarbons in the survey area but it does not identify the depth of the reservoir. However, when integrated with other surveys it can double the success rate of exploration and thus reduce the risk.
Samples are collected at less than 50 centimeters deep and can be analyzed over a period of 12 months.
