Simple Software Solution for Porosity Analysis of Shale
Show Description
As shale gas has attracted substantial interests in recent years, characterization of unconventional mudstone reservoirs is becoming more and more important, especially for production planning. Sample based information such as the compositional and textural framework is one of the objects of typical analysis for shale-gas reservoir rocks. However, obtaining such shale information is challenging because of its multiple scales(micron- and nano-). Investigation of pore networks in mudrocks plays a vital role in shale characterization. In a common classification, major pore types include inorganic interparticle pores, inorganic intraparticle pores and organic-matter pores [1]. Especially, intraparticle pores within organic matter (kerogen) are related to thermal maturation of organic matter. Pores form when kerogen converts to hydrocarbon species such as liquids or gases. Due to this reason, a full study of organic matter pores on dimension, shape, location, porosity, connectivity and permeability is demanded.
