Velocity modeling is built for the purpose of time-to-depth conversion or for seismic depth imagining of the subsurface. … WebDepth conversion methods can be separated into two broad categories: direct time-depth conversion, and velocity modeling for depth conversion. Whichever method is …

WebDepth conversion, ideally, is an iterative process that begins with proper seismic processing, seismic velocity analysis and study of well data to refine the conversion. Acoustic logs, check-shot surveys and vertical seismic profiles can aid depth conversion efforts and improve correlation of well logs and drilling data with surface seismic data. WebSep 8, 2024 · During time-depth conversion, only the top and bottom of Upper Kirkuk are calibrated with wells, the inner sublayers are very difficult to be calibrated without clear reflection characteristics. ... Due to the procedure of depth to time and time to depth conversion in time-domain seismic inversion, the application of the method is restricted …

This method involves compiling time and depth pairs from well data to your target horizon using a single layer. The time depth pairs are converted into average velocity values and then interpolated (gridded) to produce a velocity map. The velocity map is then multiplied by the time map to produce a … See more This is a method that uses constant velocities for each layer. The interval velocity is the depth thickness (isochore) divided by the time … See more Seismic processing velocities have the advantage of being a regularly sampled grid (with no spatial bias) with a 3D survey and a regularly sampled set of lines in a 2D survey. Typical … See more A velocity function is a mathematical formula which relates velocity (or depth directly) to travel time.
