Claim One:
1. A computer-implemented method comprising: creating, by a computer system, a model of an underground formation, the model defining a plurality of modeled values for each of a plurality of horizontal locations within the underground formation, the creating comprising: calculating a set of probabilities indicative of a likelihood of finding abutting geological layers at a first horizontal location within the underground formation; estimating a plurality of successions of geological layers and a thickness or a porosity of each geological layer of each succession to create a plurality of estimated successions associated with the first horizontal location, based on the calculated set of probabilities; comparing each of the estimated successions with a measured succession of geological layers at the first horizontal location, as determined by a seismic survey of the underground formation; and selecting from among the plurality of estimated successions a succession of geological layers that most closely matches the measured succession, based on the comparison, wherein the selected succession of geological layers is used to define the plurality of modeled values for the first horizontal location.
