Abstract:
1. A method comprising: obtaining, with a computer, a 3D seismic volume having a set of cross sections; selecting, with the computer, at least a first cross section and a second cross section from the set of cross sections; identifying, with the computer, a geologic object in the first cross section; estimating, with the computer, a transformation vector between the first cross section and the second cross section, wherein the transformation vector determines a pixel to pixel correspondence between the first cross section and the second cross section and is determined by shape deformation and movement of boundaries of the geologic object in the second cross section relative to the first cross section; calculating, with the computer, boundaries of the geologic object in other cross sections from the set of cross sections by using the estimated transformation vector; and generating, with the computer, a subsurface model that includes the boundaries of the geologic object, and using the subsurface model and the boundaries of the geologic object to identify hydrocarbon bearing zones within a reservoir for hydrocarbon exploration or production.
