When multiple seismic surveys are acquired over the same area using different technologies that produce data with different frequency content, it may be beneficial to combine these data to produce a broader bandwidth volume. We have developed a workflow for matching and blending seismic images obtained from shallow high-resolution seismic surveys and conventional surveys conducted over the same area. The workflow consists of three distinct steps: (1) balancing the amplitudes and frequency content of the two images by nonstationary smoothing of the high-resolution image, (2) estimating and removing variable time shifts between the two images, and (3) blending the two images together by least-squares inversion. Our workflow is applied successfully to images from the Gulf of Mexico.
