TLDR
The Utica Shale and its reactivity with CO2 and water is examined using scanning electron microscopy, N2 and CO2 sorption isotherms, mercury intrusion porosimetry, and X-ray scattering methods to assess alterations in the shale matrix that could impact flow pathways and ultimately, oil recovery factors and carbon storage potential.About:

How can biogeomechanical alterations in shales impact caprock integrity and CO2 storage
TL;DR: In this paper, the authors investigated how localized and bulk biogeomechanical alterations could potentially impact caprock integrity and CO2 storage in depleted shale reservoirs, and found that microbially-altered local and bulk mechanical properties can enhance the long-term caprock security by increasing the localized (19% unconfined compressive strength, −20% Poisson's ratio, +35% fracture toughness) and bulk (50% un-confined and bulk) mechanical integrity; decreasing permeability (−93%) and porosity (−38%); altering the clay mineral content

TL;DR: In this paper, small-angle and ultra-small-angle neutron scattering (SANS and USANS), low-pressure adsorption (N2 and CO2), and high-pressure mercury intrusion measurements were performed on a suite of North American shale reservoir samples providing the first ever comparison of all these techniques for characterizing the complex pore structure of shales.

Characterization and Analysis of Porosity and Pore Structures
TL;DR: There are a large number of methods for quantifying porosity, and an increasingly complex idea of what it means to do so as discussed by the authors, which is why it is important to quantify the relationships between porosity and storage, transport and rock properties, however, the pore structure must be measured and quantitatively described.

Porosity of Devonian and Mississippian New Albany Shale across a maturation gradient: Insights from organic petrology, gas adsorption, and mercury intrusion
TL;DR: In this paper, the evolution of porosity in shales with increasing maturity was examined in a suite of five New Albany Shale samples spanning a maturity range from immature (vitrinite reflectance, Ro 0.35%) to postmature (Ro 1.41%).
