Effect of heterogeneity of brittle rock on micromechanical extensile behavior during compression loadingDownload
A grain-based Universal Distinct Element Code model was developed to generate a deformable polygonal grain-like structure to simulate the microstructure of brittle rock. It takes into account grain-scale heterogeneity including microgeometric heterogeneity, grain-scale elastic heterogeneity, and...
Wellbore seismic and core sample measurement analysis: integrated geophysical study of the Lake Bosumtwi impact structure, GhanaDownload
Wellbore seismic measurements were recorded in the Lake Bosumtwi impact structure, Ghana, in 2004. A full range of petrophysical measurements were also performed in the laboratory on core samples from the same boreholes. The Vertical Seismic Profile shows low velocities for both P and S waves in...
