... brittleness index is a key metric for quantifying intrinsic rock strength, obtaining this data typically necessitates laboratory core measurements or complex multi-mineral inversion results from well logs. Notably, existing elastic-based and log-based brittleness indices often fail to effectively identify...

... Due to the lack of stiffness coefficient c12 information in seismic data of VTI (vertical axis symmetry transverse isotropy) media, it is still challenging to obtain the brittleness index of transversely isotropic (BIVTI) directly from seismic data. In this paper, we established the approximate...

... and Poisson’s ratios are less affected by the lamination of coal (CL), but are significantly reduced by fracture porosity in the direction near the symmetry axis. We construct templates for the brittleness index (BI) based on this model. The templates suggest that the BI is most sensitive to the organic...

... ABSTRACT Development of the Najmah reservoir is totally dependent on recognizing naturally fractured areas with high TOC content and higher brittleness index. The reservoir section is immediately below thick layers of alternating salts and anhydrite, and the seismic data within the reservoir...

... Summary We estimate the brittleness index based on the rock mineralogy composition from log measurements from a fully cored well, located just outside the area of our seismic survey. Using density logs and P- and S-wave sonic logs in the well we map the brittleness index against Young's...
