Terra Nova, 23, 145–161, 2011 Abstract The hydrogeology of superficial (∼ 0–100 m bgl)
Hard Rock Aquifers (HRA; ie plutonic and metamorphic rocks) has so far been dominated by …

This paper reviews application of borehole flowmeters in granular and fractured rocks. Basic
data obtained in the field are the ambient flow log and the pumping-induced flow log. These …

The relationship between in-situ stress and fluid flow in fractured and faulted rock is
examined by using data from detailed analyses of stress orientation and magnitude, fracture …

Imaging with acoustic and optical televiewers results in continuous and oriented 360° views
of the borehole wall from which the character, relation, and orientation of lithologic and …

Numerical models of the enlargement of primary fissures in limestone by calcite aggressive
water show a complex behavior. If the lengths of the fractures are large and hydraulic heads …

A numerical model of flow in the vicinity of a borehole is used to analyze flowmeter data
obtained with high‐resolution flowmeters. The model is designed to (1) precisely compute …

Preferential flow path connectivity is generally cited to explain scaling effects in hydraulic
properties [Hsieh, PA, 1998. Scale effects in fluid flow through fractured geological media …

There is much current interest in determining the flow characteristics of fractures intersecting
a well bore in order to provide data for use in estimating the hydrologic behavior of fractured …

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

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 …
