Abstract

Single and multi-trace seismic attributes are widely used to help to visualize and delineate the spatial extent of depositional bodies on interpreted horizons (e.g. Wescott and Boucher, 2000; Wood et al., 2000; Posamentier and Kolla, 2003; and Chopra and Marfurt, 2007). Commonly, the internal complexities of these interpreted depositional bodies are not as well resolved due to spatial resolution constraints and low contrast. This increases the uncertainty of quantitative analyses or inferences that utilize the resulting data; e.g., reservoir presence and thickness (e.g. Widess, 1979; Wescott and Boucher, 2000). This also holds true in the delineation of structural elements; i.e., faults in seismic datasets, particularly when attempting to quantify the potential for internal barriers to act as baffles to fluid flow within individual reservoir units. Therefore, there is a need for further development and understanding of seismic attribute work flows used to evaluate geological elements imaged within our poststack seismic datasets, in order to gain an enhanced understanding of the detailed morphology, spatial extent, and temporal location of depositional and structural elements, in order to assess fully their importance and impact.
