Latest Patents

Söllner's latest patents showcase his expertise in mitigating noise and enhancing seismic imaging. One notable patent is titled "Mitigating residual noise in a marine survey with orthogonal coded pseudo-random sweeps." This invention revolves around the use of marine vibrators that emit orthogonal coded pseudo-random sweeps to generate coded signals. These signals are instrumental in activating marine vibrators in water bodies, resulting in clearer detection of wavefields emitted from subterranean formations. By cross-correlating seismic signals with signature sweeps, the method significantly reduces incoherent residual noise, leading to improved seismic data quality.

Another recent patent, "Seismic imaging with source deconvolution for marine vibrators with random source signatures," addresses the challenges of imaging subterranean structures using seismic data. This innovation involves generating an up-going pressure wavefield from marine survey data and obtaining a downgoing vertical acceleration wavefield. By deconvolving these wavefields, the resulting subsurface reflectivity wavefield can generate clearer images of subterranean formations while minimizing contamination from various sources like directivity and random signatures.
