Abstract

Untill now, in GOCAD, different objects and algorithms have been developped in order to tackle the problem of modeling petrophysical parameters inside a reservoir. Among the objects are: • GShapes allow to define curvilinear objects such as channels, creavasses, ... • Wells. • Voxets or Regular Grids, aIIows to fiII a reservoir with regular cells. • SGrids or Curvilinear Stratigraphie Grids allow to generate a grid following the sedimentary organisation of the reservoir, and limited by the reservoit boundaries .. Among the algorithms: • Stochastic Simulation of Sedimentary Bodies. This method simulates the distribution of different sedimentary bodies (GShapes) within a reservoir according to weIl data, GShape template geometries, and facies proportions. • Geostatistie algorithms coming from GSLIB perform krigings and simulations inside a grid. In this paper we present how we are merging the two approaches in order to perform a full reservoir simulation.
