WebTime-to-depth conversion is the process where seismic velocities are scaled accordingly to check shots and well logs so that geological markers and seismic horizons match in depth. Seismic data, if in depth, are stretched to time with the migration velocity, or a smoothed version of it (Jones, 2009), Web11.1 Introductory Remarks 405 11.2 Major Factors Affecting Depth Conversion Results 405 11.2.1 Velocity modelling efficiency 406 11.2.2 Well-to-seismic data correlation 406 …

WebTime-to-depth conversion means that each seismic data point in the time domain will be given a depth coordinate. Each point keeps its XY location. There is no lateral … Web2 Oct 2014 · The time-to-depth conversion strategy involves the following steps: Interpret a set of time horizons from an image volume derived from time migration; these time horizons are usually associated with layer boundaries with velocity contrast or geological … Since we use rays to perform time-to-depth conversion, it is important to ensure that … The depth structure maps derived from time-to-depth conversion or layer-by-layer … If the input times are from an unmigrated stacked section as in Figure 9.1-2a, use … We now have a set of time horizon maps (Figure 9.4-4) and a corresponding set of … The procedure for estimating layer velocities from stacking velocity … A velocity-depth model usually is defined by two sets of parameters — layer velocities … The Dix equation (), which relates rms velocities to interval velocities, is used to … Figure 9.4-37 (a) The interval velocity profiles derived from the rms velocity … WebEarly-career geoscientists and engineers, especially seismic interpreters, and anyone who needs to understand the basic theory and procedures for creating velocity models and … game ark s2 内容
