Vector based geophysical modeling of subsurface volumes

摘要

Method and system are described for modeling one or more geophysical properties of a subsurface volume. The method includes computing vector volumes from geophysical data to enhance subsurface features, where the vectors may be estimated by steps, including the following. Samples are extracted from a neighborhood around a selected data location (121). Coordinates are assigned to each sample (122). A weight is assigned to each sample as a function of the sample value (123). The sample coordinates and weights are used to fit a polynomial (124). A new value is then determined for the data location based on the polynomial fit, e.g. from the slope (125).
