Nowadays there is a clear trend towards using methods and tools that can develop multi-agent systems (MAS) capable of performing dynamic selforganization when they detect changes in the environment. Moreover, the ideas that model the interactions of a multi-agent system cannot be related only to the agents and their communication skills in gaining strength, but it is necessary to use the concep...

Reflection energy from a linear reflector comes from an integrant over an aperture often described by the Fresnel zone. Within the Fresnel zone, the diffraction energy constructively builds the reflection energy. This paper uses diffraction theory to explain the reflector edge effect on amplitude and the amplitude variation within the Fresnel zone. Thus, discuss the Fresnel zone effect for AVO ...

For optimal hydrocarbon recovery from fractured reservoirs, a critical issue is to gain an accurate understanding of the natural fracture system. Currently, fracture characterization using amplitude based technologies is routinely performed relying on amplitude versus angle/offset (AVA/AVO) and azimuth (AVAZ) to exploit anisotropic gradient behavior, which is today commonly used in the industry...

RÉSUMÉ. Le transport de contenus multimédia codés au standard MPEG-4 sur Internet est soumis à des contraintes de débit, de délai et de fiabilité. La charge et la nature du trafic sur le réseau ont des effets sur les pertes et les délais d’acheminement des paquets qui doivent être contrôlés. Dans cet article, nous proposons une technique de protection des objets audiovisuels (AVO) adaptée aux c...

Amplitude versus Angle (AVA) attributes include information about rock properties. Using a dataset from South America, we performed a multiple realization method to get multiple equal-probable AVA intercepts, gradients, and their products. We generated a 3D histogram to evaluate the variability of those AVA attributes. In the same area, we chose a 2-D section by matching it to three wells. Then...

The paper analyzes how the use of additional information obtained thought borehole gravimetric measurements affects accuracy determining parameters medium when evaluating elastic impedances in framework AVO-analysis. possibility increasing seismic survey results procedure for through gravimetry data has been demonstrated.
