Seismic illumination at each point of the interwell region can be defined as the maximum angle between the rays that pass through the point. Interfaces completely contained in the angular apertures can be imaged with first ...

A inversão completa da forma de onda (FWI - do inglês full-waveform inversion) é atualmente uma das principais ferramentas para determinar modelos de velocidades da subsuperfície com alta resolução. Nessa dissertação, a ...

Full waveform inversion is a technique used to obtain the subsurface velocity model with high accuracy. In the oil industry (mainly in reservoir characterization), it is common to use well information as priori information ...

One of the main stages of drilling an oil well is prospecting. For example, this stage is where seismic data processing for the study of soil characteristics is performed. Among many methods and algorithms used during ...

The tasks organization among computational nodes affects the performance of the program. In computationally expensive applications such as geophysical problems, the impact is more significant. The imbalance caused by ...

The increasing occurrence of imposex in marine gastropods has been related to their exposure to the tri-substituted organotin compounds tributyltin (TBT) and triphenyltin (TPhT), which have been widely used as antifouling ...

We propose an efficient methodology for the complete version of the wave oriented to a target area through the Patched Green’s Function-(PGF) method. The method consists of separating the velocity model into two regions ...
