Latest Patents

One of his latest patents is titled "Variable aperture estimation using bottom-up ray tracing." This invention involves a method and apparatus for imaging seismic data, which includes obtaining an initial model of a subsurface formation. The model consists of a grid of nodes, each with an initial dip value and origin coordinates. The process involves performing bottom-up ray tracing for each node, resulting in a set of arrival coordinates. The method further includes identifying gathers from seismic data, calculating midpoint coordinates, and estimating unique apertures for each gather based on their respective origin coordinates. The estimated apertures are stored in a table, ultimately generating a subsurface volume or image with reflectors determined by the respective gathers.

Another significant patent by Fuxian Song is "Automatic tracking of faults by slope decomposition." This method focuses on locating fault lines or surfaces in 2-D or 3-D seismic data. It leverages the principle that fault discontinuities span a wide range in the local slowness domain, while other events, such as noise, tend to be coherent. The method involves decomposing seismic data into the local slowness domain using Gaussian slowness period packets, allowing for the identification of faults represented as truncations in the space domain data.
