Neptune: a TotalFinaElf new methodology for building realistic reservoir models

@inproceedings{PernarcicRM2002,
 abstract = { Neptune's goal is to provide a realistic and consistent stratigraphic grid and facies proportion cube from hard data (facies description on cores and logs) and geological knowledge (sedimentological model and paleogeographic map). paleobathymetric curves of deposits are constructed for each well from facies description on cores and logs. Accommodation potential logs (increment of space available for sediment accumulation) are then produced from these curves and deposit thickness in the wells. The accommodation signal can be separated into two components: a common factor which represents the tectono-eustatic activity at field scale (easily extrapolated) and residuals which correspond to local variations in subsidence. 3D grids of accommodation potential and paleobathymetry can then be modelled. Energy of deposit can also be outlined. Geological inversion is therefore possible and leads to the proposal of a complex 3D prior probability field for facies modelling, with different organisations in both the transgressive and the prograding parts of the sequence. When constrained by such trends, stochastic modelling can render very realistic images of reservoir heterogeneity. This method was applied successfully in carbonate and mi xed (silici-clastic and carbonate) platform reservoirs, in which properties are highly variable and non stationary. },
