Abstract
Decompaction may be defined as a process to reconstruct the palaeothickness and the palaeoporosity distributions of a sedimentary column. This process is normally realized by computation of pore volume reduction in sedimentary histories (Perrier and Quiblier 1974). Decompaction modelling has been a subject of interest because of its uses in quantitative geohistory analysis, reservoir evaluation and fluid migration studies in sedimentary basins (Sclater and Christie 1980; Bessis 1985; Bertram and Milton 1989). Petroleum geologists, while preparing palaeogeographic or palaeostructural reconstructions, must consider how thicknesses of strata were modified during depositional history.
