Organic petrography via incident light microscopy has broad application to shale petroleum
systems, including delineation of thermal maturity windows and determination of organo …

With the increasing interest in unconventional resource plays, there have been important
changes in the way how reservoirs and their attributes are assessed and characterized. Of …

Pore types, pore size, and pore abundance vary systematically across thermal maturity in
the Eagle Ford Formation, Maverick Basin, southern Texas. Scanning electron imaging of 20 …

Organic-matter (OM) pores are an important constituent of mudrocks and comprise the
dominant or subsidiary pore network of many shale-gas and shale-oil systems. New …

Primary sedimentary composition of shales and subsequent diagenetic modifications are
key factors in controlling the pore development and preservation in shale gas reservoirs …

Petroleum is retained in shales either in a sorbed state or in a free form within pores and
fractures. In shales with oil resource potential, organic matter properties (ie, richness, quality …

Organic-matter-hosted pores are an important aspect of pore systems in unconventional gas
shale reservoirs. Along with thermal maturity, organic maceral type critically controls the …

Mineral types (detrital and authigenic) and organic-matter components of the Ordovician-
Silurian Wufeng and Longmaxi Shale (siliceous, silty, argillaceous, and calcareous/dolomitic …

Organic-matter porosity is an important component in mature organic-rich shales providing
storage capacity for liquids and gases. This study presents 2D microstructural …

Low and high resolution petrographic studies have been combined with mineralogical, TOC,
RockEval and porosity data to investigate controls on the evolution of porosity in …
