seismic coherency is a measure of lateral changes in acoustic impedance that are caused by variations in structure, stratigraphy, lithology, porosity, and fluid content. seismic coherency is a geometrical attribute that establishes temporal and lateral relationships with other attributes. seismic coherency can be defined by coherency attributes. when coherency attributes are applied to seismic ...

6 Recent studies attribute land double-frequency (DF) microseism observations to deep7 water generation. Here we show that near-coastal generation is generally the dominant 8 source region. This determination is based on observations at land and ocean seismic 9 stations, buoys, gravity wave hindcasts, and on beamforming results from continental 10 seismic arrays. Interactions between opposing o...

A joint analysis of global seismicity and seismic tomography indicates that the seismic potential of continental intraplate regions is correlated with the seismic properties of the lithosphere. Archean and Early Proterozoic cratons with cold, stable continental lithospheric roots have fewer crustal earthquakes and a lower maximum earthquake catalog moment magnitude (Mcmax). The geographic shear...

reservoir models are initially generated from estimates of specific rock properties and maps of reservoir heterogeneity. many types of information are used in reservoir model construction. one of the most important sources of information comes from wells, including well logs and core samples. unfortunately well log and core data are local measurements that may not reflect the reservoir behavior...
