- obtaining seismic data;
obtaining a set of topologically consistent surfaces that correspond to the seismic data;
enumerating the surfaces in the depth domain;

using a computer to generate an age mapping volume;
choosing an extent of the age domain;
using a computer to generate a depth mapping volume;
using both the age mapping volume and the depth mapping volume to transform, on a computer, geophysical, geologic, or engineering data or interpretations between the depth domain and the age domain, and between the age domain and the depth domain; and
outputting the geophysical, geologic, or engineering data or interpretations transformed by at least one of the age mapping volume and the depth mapping volume.

Abstract
Method for transforming geologic data relating to a subsurface region between a geophysical depth domain and a geologic age domain. A set of topologically consistent surfaces (252a) is obtained that correspond to seismic data (252). The surfaces are enumerated in the depth domain. An age is assigned to each surface in the depth domain (255). The age corresponds to an estimated time of deposition of the respective surface. An age mapping volume is generated (256). An extent of the age domain is chosen. A depth mapping volume is generated (260). Both the age mapping volume and the depth mapping volume are used to transform geophysical, geologic, or engineering data or interpretations (258, 263) between the depth domain and the age domain (268) and vice versa (269). The geophysical, geologic, or engineering data or interpretations transformed by at least one of the age or depth mapping volume are outputted.
