High-effort three-dimensional (3D) Previous HitseismicNext Hit data collected by the Abu Dhabi Company for Onshore Oil Operations are some of the highest quality data ever collected over a carbonate field. These data provide the opportunity to test the limits of high-end Previous HitseismicNext Hit technologies in carbonates and to demonstrate the value of Previous HitseismicNext Hit for integrated carbonate reservoir characterization. Previous HitSeismicNext Hit data were integrated with other subsurface data to develop a new, sequence stratigraphic based reservoir framework. The Lower Cretaceous (Aptian) reservoir records a large-scale transgressive-regressive depositional cycle that is divided into six depositional sequences. Reservoir architecture and quality vary predictably within the sequence framework and correspond closely to variations in Previous HitseismicNext Hit properties. Sequence-stratigraphic surfaces define the 3D distribution of flow barriers and flow units within the reservoir and are used to guide framework and rock property distributions in 3D reservoir models.

Quantitative Previous HitseismicNext Hit information on reservoir architecture and porosity variations provides a new understanding of reservoir heterogeneity and the underlying geologic controls. Multi-Previous HitattributeNext Hit volume interpretation and co-rendering techniques help to visualize geologic and reservoir variations and provide a volume-based framework for reservoir evaluation. Together, the sequence-based reservoir framework and 3D Previous HitseismicNext Hit data provide an integrated platform for addressing a range of production and performance issues. Applications of these results include: 1) 3D Previous HitseismicNext Hit visualization as a tool for optimizing well placement, identifying by-passed reservoirs and evaluating reservoir connectivity, 2) integration of quantitative, volume-based Previous HitseismicTop information into reservoir models, 3) maximizing recovery through full integration of all subsurface data, and 4) enhanced communication among geoscientists and engineers leading to improved reservoir management practices.
