Caprock integrity evaluation for geosequestration of CO2 in depleted petroleum reservoirs.
… during CO2 geosequestration can impact the brittleness of the formations due to changes in their mineralogical compositions during the geochemical reactions. Therefore, studies on the co-injection of CO2 with other acid gases from industrial emissions and their impact on caprock integrity …

Variations in mineral abundance within a single horizontal well path in the Woodford Shale, Arkoma Basin, Oklahoma
… data were used to calculate a mineral-based brittleness index (Wang and Gale, 2009), which was compared to the measured frack gradient across perforations of the Carleigh 6H-32 well. In addition, the total organic matter content (TOC) was approximated in the same samples using loss on …

Bulk Rock Major and Trace element Chemostratigraphy of the Cretaceous Lower Eagle Ford Formation in South Texas
… reflected by low K/Al ratios (0.24), and high brittleness index (0.83) related to carbonate rich adjacent units.

A study on the use of indigenous New Zealand plant fibres for producing biomorphic hydroxyapatite fibres and chars used in reinforcing biomedical hydroxyapatite sourced from cattle bone
… diametral tensile strength, Vickers hardness, brittleness index and indentation fracture toughness values of ca. 26 ± 0.8 MPa, 5 ± 0.1MPa, 190 ± 30 HV, 4 ± 0.2 and 0.5 ± 0.1 Mpa.m1/2 respectively. Both types of composites showed an increase in mechanical properties up to certain maximum values …

Case history-based analysis of liquefaction in sloping ground
… case histories; and (3) the relation between brittleness index and su(liq). Finally, three case histories subjected to six separate earthquakes were used to evaluate the proposed liquefaction evaluation procedure. These cases were analyzed for susceptibility, triggering and post triggering to …
