Abstract
A method for estimating subsurface elastic parameters is described herein. One or more slowness vectors may be determined based on a vertical seismic profile of a subsurface area. A model containing anisotropy parameters and a well deviation estimate may be generated based on survey data. The slowness vectors may be corrected for the well deviation estimate based on the model. One or more modeled slowness vectors may be calculated using the corrected slowness vectors and the anisotropy parameters in the model.
