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.
