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.
In this paper, we propose 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:
(a) balancing the amplitudes and frequency content of the two images by non-stationary smoothing of the high-resolution image;
(b) estimating and removing variable time shifts between the two images; and
(c) blending the two images together by least-squares inversion.
The proposed workflow is applied successfully to images from the Gulf of Mexico.
