Geochemical microbial identification technique was developed over 40 years ago in the United States and commercialized in Latin America since 20. Has minimal environmental and social impact. This is due to the ease of sample collection in the project area.
It seeks to detect through biological laboratory incubation the presence of butane metabolizing bacteria. Geochemical microbial identification is supported by the theory of vertical microseepage of gas from oil trapped in reservoirs. The released gases change the composition of the different layers of the subsoil during its migration up to the surface.
It allows to determine the presence of hydrocarbons in the project area. However does not identify the depth or type of trap present. Colonies of bacteria exist thanks to leaks of hydrocarbons from the reservoir to the surface. Integrated with other surveys it may double the exploration success rate and reduce risk.
The samples analyzed in the laboratory require incubation and dilution process to determine the number of colonies present in the sample. This technique works in all ecosystems, with significant processing variations in offshore samples.
Samples are collected at less than 50 centimeters deep and can be analyzed over a period of 12 months.
