Abrégé

A computer supported method, computer system and computer program product for exploring and producing a subsurface heterogeneous hydrocarbon source and generating a predictive production map of an area under investigation, based on microbial prospecting. Microbial data representative of microbial activity attributable to hydrocarbon microseepage and hydrocarbon productivity data of a plurality of geographic locations are retrieved and correlated by the computer in a data correlation algorithm, providing a threshold hydrocarbon productivity quantity and a truncated set of the retrieved microbial data. The set identifies individual types of the microorganisms and corresponding individual weighting factors computed by the data correlation algorithm, for distinguishing prospective hydrocarbon productivity quantities from non-prospective hydrocarbon productivity quantities. An estimated subsurface hydrocarbon productivity quantity for a geographical location of the area under investigation is provided by count weighting retrieved microbial data of this location for microorganisms identified in the truncated set, applying the individual weighting factors.
