1. A computer-implemented method to intelligently group seismic interpretation data in an inventory tree based on processing history, the method comprising: generating a seismic interpretation model of a hydrocarbon reservoir, the seismic interpretation model comprising seismic volume and horizon datasets; selecting an input dataset within the seismic interpretation model; performing an operation on the input dataset to thereby generate an output dataset; generating a record of the performed operation, the record also reflecting a relationship between the input and output datasets; and utilizing the record to generate an inventory tree comprising: the input dataset; the output dataset; and the relationship between the input and output datasets.
