The well selected for the application of our attenuation theory and extraction ofattenuation attributes from seismic data is the Texaco well (API 177104132700) in Block313 of Eugene Island in the Gulf of Mexico (Well 2700). The rock physics diagnosticsindicates that the rock can be described by the uncemented (soft-sand) model. Thismodel is used to predict the S-wave velocit...

Tunnel portal sections always suffer serious damage under strong earthquakes. This paper aims to study the seismic performance of lining strengthening method in soft rock section by employing model test. Firstly, shaking table test considering cases, modified input motions, boundary condition, and monitoring equipment are conducted simulate response tunnel section. Then, increasing concrete gra...

Stochastic simulation of facies or geologic units is important before the assignment of continuous rock properties. Sequential indicator simulation (SIS) remains a reasonable approach when there are no clear genetic shapes that could be put into object-based modeling. Constraining SIS to soft secondary data coming from geological interpretation or geophysical measurements is important. There ar...

Rock climbers' grip techniques may result in a variety of hand injuries. Minor injuries such as soft-tissue damage, flexor tendon strain, tendinitis or tenosynovitis, joint contractures, and carpal tunnel syndrome may be treated by a primary care physician. Patients who have pulley ruptures should be referred if there is any uncertainty about the diagnosis. Because of controversies regarding su...

Clay, as a rock term, describes a soft, loose, earthy material containing particles with an average grain size of less than than 0.004 mm (4 mm) in the Wentworth grain size scale and less than 0.002 mm (2 mm) in most soil investigations. Clay is composed mostly of clay minerals, but may also contain quartz, feldspar, carbonates, ferruginous material, and other non-clay materials. All clays, apa...

The role of predation in structuring soft-sediment communities varies as a function of the number and composition of predators that co-occur in a given habitat. In Bonne Bay, Newfoundland, contrasting abundances or predators in different areas of the bay may contribute to different regulatory roles of predators on infauna. To test this hypothesis, results from a field exclusion experiment were ...
