Upper crustal rocks contain cracks of diverse sizes, shapes and orientations. Predicting their
influence on the effective elastic properties of a rock poses a challenging problem of …

A series of 20 chevron cracked notched Brazilian disc (CCNBD) samples of Westerly granite
were failed in a standard Mode I tensile test at room temperature in order to evaluate the …

Seismic Petrophysics in Quantitative Interpretation is written for oil and gas industry
professionals and academicians who are concerned with the use of seismic data in …

Uniaxial compression tests on rocks, if conducted at stresses below failure, typically exhibit
both non-linearity and hysteresis in the stress–strain curve. In a series of three papers in …

As has been known for some time, velocities of elastic waves propagating in most
subsurface formations exhibit directional dependence, or seismic anisotropy. On their way to …

The heterogeneity of a carbonate reservoir exists at all scales and always presents a
challenge because it cannot be studied visually during laboratory measurements …

We measured Vp/Vs ratios of thermally cracked Westerly granite, thermally cracked Carrara
marble and 4% porosity Fontainebleau sandstone, for an effective mean pressure ranging …

The noninteraction approximation (NIA) is the simplest effective media theory that describes
the overall elasticity of fractured rocks. If the NIA is used for fracture characterization, its …

We simulate induced seismicity within a geothermal reservoir using pressure-driven stress
changes and seismicity triggering based on Coulomb friction. The result is a forward …

Exploration and development of naturally fractured reservoirs rely on understanding and
interpretation of certain signatures associated with seismic waves propagating through …
