The scratch test is a quasi-non-destructive method made up of pushing a tool across the
surface of a weaker rock at a given penetration depth. The unconfined compressive strength …

Success of a hydraulic fracturing operation depends on the height and width of the induced
fractures. One of the critical components controlling fracture size is fracture toughness of the …

This study introduced a mode II fracture energy approximation based on scratch test results
and a phase field modeling approach. Using a length-insensitive approach, an analytical …

Abstract The upper Cretaceous Naparima Hill Formation, a primary source rock for
conventional oil and gas reservoirs in Southern and Columbus basins, Trinidad is now …

The integrated geomechanical process is a novel and resourceful approach that coalesces
multidisciplinary scientific fields with geomechanics to provide solutions to complex scientific …

The magnitude of elastic anisotropy in shale is a function of composition, texture, and fabric.
Rock components such as mineralogy, organic content, clay mineral orientation, alignment …

Complete rock property characterization based on whole core acquisition helps generate
reservoir specific correlations for play characterization. Conventional whole core ensures …

The scratch test is a non-destructive method made up of pushing a tool across the surface of
a weaker rock at a given penetration depth. The uniaxial rock strength (UCS), fracture …

A micro-scale investigation of mechanical rock properties is carried out in this study. Two of
the main mechanical properties being investigated are rock elastic properties, identified by …

Fracture toughness (K IC) is an important component in hydraulic fracturing design. In this
work, Semicircular bend test (SCB) is combined with Digital Image Correlation (DIC) solution …
