Interpolation algorithms have been developed in order to visualize the evolution of the dynamic parameters in fluid-flow/compaction models (one and two dimensional), created by the Basin Analysis Group at USC. One of the major features of these graphics codes is the treatment of instantaneous faults, whether vertical or slant, in the two dimensional code. Both one dimensional and two dimensional fluid-flow/compaction codes have been applied in the study of two abnormally pressured basins: (1) a 5 million year old basin in Indonesia, which developed in a deltaic environment, and currently has an overpressured profile in strongly undercompacted shaly layers. Furthermore, the basin is controlled by a major growth fault system, whose behavior through time is examined and highlighted, according to the pressure data available, and (2) the Elmworth field, which is part of the Deep Basin in Western Canada, characterized by fluid pressure lower than hydrostatic in some of the Lower Cretaceous sandy formations. The two dimensional model (GEOPETII) succeeded in trapping gas in the deepest part of the basin, as appears to be the case in Elmworth thus simulating an unconventional hydrocarbon trap, which, in turn, is the cause of subnormal pressure occurrences.
