Recent advances in seismic acquisition, processing, and visualization techniques provide the opportunity to image carbonate reservoir architecture with unprecedented resolution. In particular, the increase in three-dimensional (3-D) seismic data acquisition and the improvements in processing techniques have contributed to these advances and have resulted in higher-resolution imaging of sedimentary bodies. In addition, the analysis of seismic attributes is a developing methodology to quantify the volumes and rock properties of these bodies (Masaferro et al., 2004). These advances in volume visualization that allow imaging of the morphology of ancient carbonate systems rivals images from satellite data in the modern environments (Figure 1). The additional advantage of seismic data is that the imaged deposits can be displayed at various stratigraphic levels thereby documenting the evolution of the depositional environment through time. The paleo-geomorphology can now be accurately imaged for carbonate systems constructed by extinct reef builders that have no modern analogs. This capability offers the unique opportunity to exploit 3-D images for questions regarding the growth pattern of different reef communities, their paleoecology, and reservoir heterogeneities in ancient systems. In addition, analyses of seismic attributes are a developing methodology to quantify the volumes and rock properties of sedimentary bodies. When relating the stratigraphic architecture to the forming processes, such information is invaluable to geologists who are often limited to two-dimensional (2-D) sections in outcrops or to the plan view in the modern depositional environment.

Seismic Imaging of Carbonate Reservoirs and Systems
Recent advances in seismic acquisition, processing and visualization techniques image carbonate strata with unprecedented resolution. This volume documents the current state of the art in seismic imaging and interpreting of carbonate systems and captures the dynamics of the carbonate system on a large exploration scale and on a small reservoir scale. The book emphasizes the newest approaches in seismic visualization, seismic sedimentology and stratigraphy, seismic attribute analysis and their application for building improved 3-D reservoir models. Among the topics covered are the delineation of the complex histories of carbonate platform sequences from seismic data, the relationships between geometries and forming processes, the imaging of faults for improved mapping of potential fluid migration pathways, and use of seismic attributes for the extraction of rock properties in the sedimentary bodies. The book illustrates the power of integrating seismic and geological data to better predict of the architecture and heterogeneities in carbonate depositional systems. As such the book will be a useful reference for both geologists and geophysicists.
