Direct wave arrivals are the most robust signals to determine velocity. They have been used for almost a century in hydrocarbon exploration. This is because the arrival time is explicitly available and provides a direct measurement of the average vel

Summary One of the most difficult tasks that an exploration geologist must undertake is to correctly assess the economic viability of a potential prospect and the risks associated with drilling it. This is made especially challenging because of uncer

Modeling of seismic wave propagation plays a key role in almost every aspect of exploration seismology. Fundamentally, it provides a means of understanding the character of recorded seismic data. Although analytical or semianalytical solutions exist

Modeling of a constant Q: Methodology and algorithm for an efficient and optimally inexpensive viscoelastic technique

Autor: Joakim O. Blanch, William W. Symes, Johan O. A. Robertsson

Publikováno v: GEOPHYSICS. 60:176-184

Linear anelastic phenomena in wave propagation problems can be well modeled through a viscoelastic mechanical model consisting of standard linear solids. In this paper we present a method for modeling of constant Q as a function of frequency based on
