Measurements of seismic anisotropy in fractured rock are used at present to deduce
information about the fracture orientation and the spatial distribution of fracture intensity …

The Mallik 2L‐38 research well was drilled to 1150 m under the Mackenzie Delta, Canada,
and penetrated a subpermafrost interval where methane hydrate occupies up to 80% of the …

Introducing the first, self-contained reference on acoustic waveform logging Acoustic
measurements in boreholes were first made as a specialized logging technique in …

A general expression is derived for the dispersion relations and the impulse response of a
radially layered borehole. The model geometry consists of a central fluid cylinder …

The frequency dependence of seismic properties of fully saturated rocks can be related to
wave‐induced fluid flows at different scales. The elastic dispersion and attenuation of four …

ABSTRACT Three-dimensional (3-D) printing provides a fast, cost-effective way to produce
and replicate complicated designs with minimal flaws and little material waste. Early use of 3 …

Stoneley waves in permeable boreholes are diagnostic of formation permeability because
their propagation is affected by the dynamic fluid flow at the borehole wall. This flow using …

Wave propagation and attenuation in subsurface rock masses could be highly affected by
rock joints filled with fluids. However, the understanding of acoustic behaviours across fluid …

In fractured rocks, the amplitudes of propagating seismic waves decay due to various
mechanisms, such as geometrical spreading, solid friction, displacement of pore fluid …
