Three-dimensional finite-element modeling was performed to investigate the response to
fractures of the Formation MicroScanner (Mark of Schlumberger), which records high …

Electrical and electromagnetic geophysical techniques have reached a high level of
technological sophistication since they were first used in boreholes less than one hundred …

Borehole imaging devices are currently available for both wireline and logging-while-drilling
(LWD) environments for use in both openhole and cased wells. Most wireline, and all LWD …

A comprehensive suite of geophysical logs was collected in the SAFOD Pilot Hole from a
depth of 775 m to 2150 m in highly fractured Salinian granite. The Pilot Hole intersected …

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

One of the main difficulties encountered when characterizing the hydrodynamic properties of
a fractured aquifer is to identify the preferential flow paths within it. Different methods may be …

Numerous laboratory and field experiments suggest that electrical properties of fractured
rocks may provide critical information regarding the topological properties of the underlying …

Ultrasonic image logs acquired in the DFDP‐2B borehole yield the first continuous,
subsurface description of the transition from schist to mylonite in the hangingwall of the …

We studied the electric response of fractures with laboratory experiments and numerical
simulations for a full-bore formation microimaging tool. The laboratory setup was designed …
