Latest Patents

Lian Duan's latest patents include groundbreaking methods for the separation of blended seismic survey data. One patent details techniques for deblending sources in multi-source geophysical survey data, applicable to both marine and land-based data. This method involves generating multiple sets of deblended receiver traces by iteratively applying a coherency filter to estimated sets of deblended receiver traces. The process continues until a termination condition is met. In some cases, the coherency filter is adjusted based on the results from the previous iteration, which may include the application of a 3D projection filter.

Another patent focuses on the separation of blended marine seismic survey data acquired through simultaneous multi-source actuation. This technique aligns recorded data to a primary source and applies an iterative deblending procedure to produce residual terms and deblended estimates for both primary and secondary sources. The resultant data is sorted in a manner that renders the secondary sources incoherent with respect to the primary source, utilizing a different sorting domain than that used in prior iterations. The deblending procedure incorporates coherency filtering, which is weighted according to a signal-to-noise metric derived from the data.
