Abstract

A method of estimating a velocity of a geological layer includes providing a first, initial model including an interval velocity associated with a subsurface location and an uncertainty associated with the interval velocity; providing data including an actual or approximated root-mean-square (RMS) velocity associated with a subsurface location and an uncertainty associated with the RMS velocity; and estimating a second model including an interval velocity associated with a subsurface location and an uncertainty associated with the interval velocity, based on the interval velocity and the uncertainty of the first model, and the RMS velocity and the uncertainty of the data.
