Scale and data type
Correlations with well data, such as cuttings, cores, or well logs, can be done to a much higher resolution than seismic scale correlations. The scale of a seismic wavelet limits the scale of correlations within a seismic section. The geologist must refine these correlations to a higher resolution using well data to more accurately define the location of seals and reservoirs.
Scale and trap detection
Scale makes a difference in ease of detection and, hence, affects risk. In Figure 1, Pennsylvanian (323.2 Ma) carbonate reef margin depositional sequences from the Delaware and Paradox basins, U.S.A., are compared. Note the difference in scale and how it affects seismic interpretation. Seismic detection of the Paradox basin traps is much more difficult because of the wavelength of the seismic wave vs. the reservoir thickness.
