AB - This paper describes how deterministic information about reservoir compartmentalization can be derived from the study of variations in reservoir fluid composition (oil and water). Oil compositional differences (e.g. PVT data, GC fingerprints) between-well, especially those that relate to changes in density, are useful indicators of reservoir compartmentalization. Such differences would be rapidly mixed by density-driven convection; their preservation indicates a barrier to fluid flow. Where suitable samples are available (e.g. core extracts, multiple DSTs), oil variations within-well would help identify barriers to vertical flow. Water variations are particularly useful if examined on the intra-well scale, e.g. by using residual salt analysis of strontium isotopes (sensitive indicators of water composition) from core samples. Sr variations in water and oil legs reflect the ability of waters to mix and the detailed oil-filling history. Both help identify barriers to vertical fluid flow. The integration of such deterministic data with other measurements (e.g. pressure, sequence stratigraphy), and with stochastic modelling, will provide the ultimate reservoir description.
