High-effort three-dimensional (Previous Hit3DNext Hit) seismic Previous HitdataNext Hit collected by the Abu Dhabi Company for Onshore Oil Operations are some of the highest quality Previous HitdataNext Hit ever collected over a carbonate field. These Previous HitdataNext Hit provide the opportunity to test the limits of high-end seismic technologies in carbonates and to demonstrate the value of seismic for integrated carbonate reservoir characterization. Seismic Previous HitdataNext Hit were integrated with other subsurface Previous HitdataNext Hit 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 seismic properties. Sequence-stratigraphic surfaces define the Previous Hit3DNext Hit distribution of flow barriers and flow units within the reservoir and are used to guide framework and rock property distributions in Previous Hit3DNext Hit reservoir models.

Quantitative seismic information on reservoir architecture and porosity variations provides a new understanding of reservoir heterogeneity and the underlying geologic controls. Multi-attribute 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 Previous Hit3DNext Hit seismic Previous HitdataNext Hit provide an integrated platform for addressing a range of production and performance issues. Applications of these results include: 1) Previous Hit3DNext Hit seismic visualization as a tool for optimizing well placement, identifying by-passed reservoirs and evaluating reservoir connectivity, 2) integration of quantitative, volume-based seismic information into reservoir models, 3) maximizing recovery through full integration of all subsurface Previous HitdataTop, and 4) enhanced communication among geoscientists and engineers leading to improved reservoir management practices.
