Fluid flow and mass transport in geological materials are crucial in diverse Earth science
applications. To fully understand the behavior of geological materials in this context, the …

Hydraulic fracturing of unconventional oil/gas shales has changed the energy landscape of
the US Recovery of hydrocarbons from tight, hydraulically fractured shales is a highly …

Much attention have been recently paid to the upper Ordovician Wufeng shale (O 3 w) and
lower Silurian Longmaxi shale (S 1 l) in the Jiaoshiba area of Sichuan Basin, which is now …

Matrix-related pore networks in mudrocks are composed of nanometer-to micrometer-size
pores. In shale-gas systems, these pores, along with natural fractures, form the flow-path …

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 …

Mudstone is the most abundant sedimentary rock and variously acts as sources, seals, and
shale gas reservoirs in petroleum systems. Many important physicochemical properties of …

Shales are ubiquitous rocks in sedimentary basins, where their low permeability makes
them efficient seals for conventional oil and gas reservoirs and underground waste storage …

ABSTRACT Low-maturity Boquillas Formation (Eagle Ford Formation–equivalent) organic-
lean calcareous mudrock samples collected from outcrop were heated in gold tubes under …

Imaging and image analysis of shale provides insights into the pore and fracture networks,
disposition of compositional elements, and signatures of diagenesis and fluid flow …

Abstract Four Haynesville Shale and four Bossier Shale samples were investigated using a
combination of Scanning Electron Microscopy (SEM) and Broad Ion Beam (BIB) polishing …
