Proposition curve: A tool for reservoir modeling and for improvement of sedimentological interpretations
- Institut Francais du Petrole, Rueil-Malmaison (France)
The IFP and Center of Geostatistics of Paris School of Mines have been working on reservoir characterization modeling since 1986. Emphasis has been placed upon the acquisition of geological data from outcrops and definition of the pertinent parameters that can be quantified which will constrain the simulations. It has been demonstrated that detailed sequence and cyclostratigraphy studies are necessary in order to provide the boundaries of the reservoir units, horizontal reference level used for computations, and a sequential ordering of lithofacies. Mathematical tools have also been created. Two quantitative parameters of primary importance for modeling are proportion curves of lithofacies and variograms. In the development of an accurate reservoir model, two points should be emphasized. (1) The quality of the preliminary sedimentological study is often inadequate for a quantitative modeling and limited data creates correlation problems. (2) Proportion curves are very powerful for refining the sedimentological interpretation and/or testing different hypotheses of correlation. These points will be illustrated with proportion curves computed mainly in fluvial or fluvial to deltaic environment from both outcrop analogs and subsurface field data.
