Latest Patents

Turquais's latest patents include innovative methods and systems to interpolate seismic data. This disclosure is directed to processes and systems that generate enhanced-resolution seismic images by interpolating sparsely recorded seismic data. Structured dictionary learning is employed to train a set of basis vectors, called 'atoms,' and corresponding sparse coefficients on patches of the recorded seismic data. The atoms are constrained to represent the geometric structure of reflection events in the recorded seismic data gather. Linear combinations of the atoms are used to compute interpolated patches over a finer receiver-coordinate grid. The interpolated patches replace the original patches in the recorded seismic data to obtain interpolated seismic data that can be used to generate an image of the subterranean formation. Another significant patent involves denoising seismic data, which includes extracting a first plurality of overlapping patches corresponding to a respective seismic data window selected from a plurality of seismic data windows. This process reshapes the first plurality of overlapping patches into patch vectors and determines sparse approximations of the patch vectors based on a dictionary and a sparse coefficient vector. Denoising seismic data can also include reshaping the sparse approximations into a respective second plurality of overlapping patches and constructing a denoised version of at least one of the plurality of seismic data windows using the respective second plurality of overlapping patches.
