Near-surface geophysics uses the investigational methods of geophysics to study the nature
of the very outermost part of the earth's crust. Man interacts with this part of the earth's crust …

We use the low-frequency reflected Stoneley-wave mode to locate permeable fractures
intersecting a borehole and to estimate their effective apertures. Assuming a model in which …

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

Laboratory‐scale studies of discrete fractures lead to better understanding of the
relationship between flow properties and pore geometry. Field‐scale studies of fracture …

The distribution of flow within conductive joint sets is influenced by the geometric
arrangement of joints and the hydraulic properties of both joints and matrix. We use finite …

The study of seismic body waves is an integral aspect in global, exploration and engineering
scale seismology, where the forward modeling of waves is an essential component in …

This study investigates the propagation of borehole Stoneley waves across permeable
structures. By modelling the structure as a zone intersecting the borehole, a simple 1D …

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

Field estimates of the normal and shear compliance of water saturated fractures were
obtained from a seismic experiment carried out on a wave‐cut platform of Upper Caithness …

The seismic visibility of fractures depends on the magnitude of their normal and shear
compliance and how these quantities vary with the scale of the fracture and depth of burial …
