Application of the Forward Modelling of Sequence Stratigraphy & Diagenesis to The Upper Cretaceous Carbonates Of Western Iraq

Abstract

Dynamic forward modelling of carbonate diagenesis and sequence stratigraphy relies on the understanding of the different process which provide a high resolution prediction of the geometry of porous and permeable zones within carbonate reservoirs. The fundamental process can be derived from tetonics, eustasy, and climate. The application of such models can yield a rapid cost effective reservoir characterization. A two dimensional model of the Upper Maastrichtian carbonates of Western Iraq was constructed. The model is based on the paragenesis of the different diagenetic processes and sequence development. As a result; highly porous dolomitized zones were determined as well as low porosity zones produced by the late diagenetic cementation.
