Patent ID: 8271244

Claim:
A method for modeling a sequence in the earth comprising: a computer creating a restored space corresponding to an area-depth model of a sequence in the earth, the area-depth model of the sequence comprising: a substantially curved upper sequence boundary; a substantially curved lower sequence boundary; where at least one of the boundaries includes an unconformity; the computer creating the restored space by transforming the sequence into the restored space to produce a restored space sequence comprising: a restored top boundary: which is the upper sequence boundary transformed into the restored space; which has a position; which is substantially flat and substantially parallel to an area axis; and a restored base boundary: which is the lower sequence boundary transformed into the restored space; which has a position; and which is substantially flat and substantially parallel to the area axis; and a gap, which is the unconformity transformed into the restored space; where the restored space is pseudo-Wheeler space; the computer performing stratigraphic layering by adding a new boundary within the restored space sequence, using as guides the positions of the restored top boundary and the restored base boundary of the sequence in restored space, and without using any other data from the model, the new boundary not including any portion of any boundary in the restored space sequence; and the computer modeling a deposition of sediments over time in the restored space.
