The elements of the research carried out on Fullerton field are presented in six chapters. In the first chapter, Ruppel and Jones describe the depositional facies and sequence stratigraphy of the reservoir based on integrated study of outcrops and subsurface data from Fullerton field. They also describe the key steps in using outcrop- and core-based facies-stacking patterns and wireline log response relationships to develop a robust reservoir framework having sufficient resolution and accuracy to form the basis for reservoir modeling and simulation. In addition, they document the products of digenesis and using three-dimensional relationships of geochemical and porosity distribution data suggest models for dolomitization and porosity development. Finally, they describe the use of two modern techniques for improved reservoir imaging: (1) borehole imaging logs for improved definition of facies distribution and cycles, and (2) 3D seismic data, to better define the distribution of reservoir porosity.
