WebJun 29, 2015 · Seismic velocities for pore pressure prediction. Because seismic velocities correlate with effective pressure in the formation, sufficiently precise estimates of velocity obtained from seismic observations can be used to determine pore pressure. In the absence of dense well control, interval velocities derived from stacking velocities are … WebThe seismic wave spends a time τi in the i th layer. The interval velocity is the actual velocity in a specific layer and is defined as vi = zi / τi For the whole ray path we can define an average velocity as ∑ ∑ ∑ ∑ = = i i i i i z v V τ τ τ Another way of averaging the velocity is to use the root-mean-square average. This is ... greggs iced apple

WebVertical seismic profiling (VSP) techniques provide a method to measure accurately the seismic velocity and lithologic structure near the borehole. The analysis of a VSP survey can also provide insight into seismic‐wave propagation especially when related to sonic measurements. But VSP and sonic log velocities (or traveltimes) are often found to … WebThe objective of acquiring crosshole data can be multipurpose; that is, the seismic velocity results obtained may be used for evaluation of lateral and vertical material continuity, liquefaction analyses ...
