The authors present a method to improve deblending results, while reducing run time and cost. The proposed seeded inversion deblending will combine inversion deblending along with a signal model with...

The authors propose a denoise workflow comprising a supervised ML (Machine Learning) model applied in the common shot domain and a self-supervised ML signal-add back model in the common channel...

Starting from the complex phase velocity, in this paper, the authors derive a system of 2nd order wave equations in 3D visco-acoustic TTI media that can be employed in Reverse Time Migration (RTM) to...

Existing 5D methods fall into two categories, surface-consistent and subsurface-consistent. In the first, seismic traces are interpolated or regularized into a grid of source and receiver lines. In...

In the current paper, the authors describe a cloud-native, fully fault-tolerant redesign of computationally intensive seismic high-performance computing (HPC) algorithms specifically optimized for...

Acquiring surface seismic data over carbon storage sites can be challenging, particularly in shallow water environments where co-located structures such as platforms, production facilities and...

In deep water Ocean Bottom Node (OBN) surveys, the use of downgoing data post-wavefield separation is a common practice due to its illumination capabilities facilitated by mirror migration. As the...

In this paper, the authors expand the application scope of DM FWI algorithm by employing two distinct datasets characterized by sub-optimal acquisition parameters. The first dataset originates from...

The main usage of wells in seismic imaging is in the velocity model building for pre-stack depth migration (PSDM) and to QC full waveform inversion (FWI) results. Both processes require velocities...

In this paper, the authors investigate the use of rotational acceleration measurements for attenuating non-compressional, or “non-P” energy on vertical particle motion records from Ocean Bottom Node...
