Abstract
Disclosed herein is a method for identification of zones of high producibility in shale reservoirs. The method includes obtaining a Total Organic Carbon (TOC) content and an organic sulfur content of a formation interval using geochemical measurements and determining a dielectric dispersion response of the formation interval using dielectric measurements. The dielectric dispersion response is processed to obtain a pore system tortuosity parameter. The pore system tortuosity parameter is correlated with a ratio of the organic sulfur content to the TOC content to identify presence of zones of mature kerogen with high or low hydrocarbon producibility, immature kerogen with a presence of clay, and on-productive or over-mature zones within the formation interval. This correlation is performed by comparing the ratio of the organic sulfur content to the TOC to an organic matter maturity threshold and comparing the pore system tortuosity parameter to a pore system tortuosity parameter threshold.
