The secondary permeability of "impervious" cover in Austin, Texas
The term "impervious" is commonly used in urban settings to describe the permeability of buildings, roads, and parking lots. When estimating recharge to an aquifer underlying an urbanized area, impervious cover becomes a ...
Variable-density groundwater flow beneath the wind-tidal flats of Padre Island
Field evidence for density-driven free convection, a potentially important groundwater transport process, has been examined at Padre Island National Seashore to determine if this phenomenon can develop under natural ...
Application of ground-based LIDAR to constrain topographic strike-variability and facies proportions of progradational San Andres Formation clinoforms, Last Chance Canyon, NM
Progradational mixed-carbonate/siliciclastic San Andres Formation clinoforms at Last Chance Canyon, New Mexico were quantitatively mapped and modeled using techniques developed for use with LIDAR (Light Dectection and ...
Kinematic analysis of outcrop-scale structures, southern Big Sur segment of Highway 1, Monterey and San Luis Obispo Counties, California
The Nacimiento Block is located in the Southern Coast Ranges of California, and consists mainly of Franciscan Complex accretionary prism rocks. It is cross-cut by the San Gregorio-Hosgri Fault Zone, a major right-lateral ...
Fracture pattern prediction using geomechanical models incorporating diagenesis, with comparison to outcrop data (Cambrian Eriboll Group sandstones, Northwestern Scotland) and core observations (Tertiary Mirador Formation sandstones, Llanos foothills Colombia)
Effective and accurate characterization of fracture populations is a key for hydrocarbon reservoir assessments. The challenge is that fractures in the subsurface are exceedingly difficult to sample in meaningful ways. ...
Effective porosity estimation from 3D seismic reflection data : Marco Polo Field, Gulf of Mexico
Seismic inversion is a geophysical tool that uses geologically constrained physical models to infer elastic interval properties (e.g., P-velocity, S-velocity, and density) from seismic interface data (e.g., reflection ...
