Image- and horizon-guided interpolation
Ehsan Zabihi Naeini, Dave Hale · 2014
Summary The blended neighbor method for image-guided interpolation enables interpolation of borehole data into a uniformly sampled 3D grid. The structural information that guides the interpolation is calculated from a seismic image and represented by structure tensors. Deriving this structural information from only the seismic image might not lead to desirable interpolated results, especially in the cases of complex structure, a low-quality seismic image and few well logs. In such cases, constraining the structure tensors with additional information is beneficial. Interpreted horizons contain structural information and are used here to construct a hybrid structure tensor field. Real data examples illustrate the ability of this new technique to achieve better conformance of interpolated properties with both the seismic image and interpreted horizons.
