Análise experimental da velocidade de ondas acústicas em função da saturação de fluido

12th International Congress of the Brazilian Geophysical Society & EXPOGEF, Rio de Janeiro, Brazil, 15–18 August 2011, 2011
One of the main goals in reservoir geophysics is to relate acoustic properties and fluid saturation. Several models can be found in the literature to relate acoustic velocities and fluid saturation. Biot-Gassman is the most used worldwide. This paper aims to show the results of an experimental work measuring P-wave velocities as fluid saturation varies

CORRELAÇÃO ENTRE VELOCIDADE DE ONDA DE PULSO E RAZÃO SÓDIO-POTÁSSIO URINÁRIOS

Revista Brasileira de Hipertensão
Introdução: As doenças cardiovasculares, lideradas pelas doenças isquêmicas do coração e cerebrovasculares, são as principais causas de morte no mundo. A velocidade de onda de pulso carotídeo-femoral (VOPcf) é um biomarcador recente e importante para avaliar a rigidez arterial, um preditor de desfechos cardiovasculares.

Tomografia com velocidade de grupo de ondas Rayleigh na região sudeste do Brasil

8th International Congress of the Brazilian Geophysical Society, 2003
Rayleigh wave dispersion curves obtained at twenty-three IRIS seismological stations were used to image group velocities throughout souheastern Brazil. The main geological provinces of the area were clearly identified in the tomographic maps. Two group velocity maps show a strong lateral variation across Parana basin, which was associated with both ...
