Method and system for geophysical modeling of subsurface volumes based on computed vectors

摘要

Method and system are described for modeling one or more geophysical properties of a subsurface volume. The method includes computing vector volumes to enhance subsurface modeling and update these vector volumes. The vectors are estimated (106) from the data, for example dip or azimuth, and then the vector volume may be updated by an optimization process (808). Flattening the original data (802) may assist the vector estimation, and associating data traces and samples of traces with labels (108) may assist the flattening. The vector volume may then be used to extract horizons (110) and generate a stratigraphic model (112) to enhance the process of producing hydrocarbons (114).
