Patent ID: 8594939

Claim:
A method, comprising: obtaining an isotropic velocity volume for a geophysical volume; obtaining time-depth pairs at downhole locations in the geophysical volume, the time-depth pairs corresponding to one or more wells located in the geophysical volume and comprising data indicative of at least one seismic survey; generating, using a computer, depth mis-tie values based on the time-depth pairs and an isotropic depth image of the geophysical volume, the depth mis-tie values being computed according to the expression: m ( x,y,t )= z iso ( x,y,t )− z ( x,y,t ) where z iso (x,y,t) is an isotropic depth based on the isotropic depth image, z(x,y,t) is a depth, and m(x,y,t) is a depth mis-tie; assigning uncertainties to the depth mis-tie values; and generating a mis-tie volume that satisfies a target goodness of fit with the depth mis-tie values.
