Although the widths of fault damage zones commonly show a positive correlation with
displacements, these relationships also show a somewhat scattered distribution. We believe …

Clay smear is a collection of fault processes and resulting fault structures that form when
normal faults deform layered sedimentary sections. These elusive structures have attracted …

Observations on tens-of-meter scale experiments of fault activation by fluid injection
conducted in shales allow exploring how aseismic and seismic events may jeopardize the …

Brittle faults and fault zones are important fluid flow conduits through the upper part of
Earth's crust that are involved in many well-known phenomena (eg earthquakes, thermal …

Good constraints on hydrogeological properties are an important first step in any quantitative
model of groundwater flow. Field estimation of permeability is difficult as it varies over orders …

Sandstone aquifers are commonly assumed to represent porous media characterized by a
permeable matrix. However, such aquifers may be heavy fractured when rock properties and …

Abstract The Chloride Mass Balance (CMB) method was used to obtain long-term recharge
values for the Santa Susana Field Laboratory (SSFL) site, which features a groundwater flow …

This paper describes the properties of faults and fractures in the Upper Cretaceous
Chatsworth Formation exposed at Santa Susana Field Laboratory and its surroundings (Simi …

Gas production from shale formations by hydraulic fracturing has raised concerns about the
effects on the quality of fresh groundwater. The migration of injected fracking fluids towards …

A combination of high resolution hydraulic tests using straddle packers and transmissivity (T)
profiling using the FLUTe flexible liner method (liner profiling) in densely fractured rock …
