We propose a multiparameter elastic FWI to simultaneously invert P-wave velocity and reflectivity. Our theoretical framework consists of two main elements for achieving this multiparameter inversion....

Least-squares imaging in image domain utilizes Point Spread Functions (PSFs) to estimate the Hessian matrix. The conventional way to compute PSFs involves cascaded operations-modelling followed by...

Seismic baseline surveys over CO2 storage reservoirs need to be sampled well enough for a proper characterization of the storage complex including potential leakage pathways over an area at least as...

Machine Learning (ML) is transforming 3D ultra-high-resolution seismic (UHRS) data processing, offering faster, consistent, and high-quality results. This study highlights ML applications in...

The main reservoirs in the Balder and Ringhorne areas consist of large Paleocene sand mounds as well as Eocene sands, including thin and steeply dipping injectite bodies. Imaging of the targets in...

The 2021 update to the Nigerian Petroleum Industry Act (PIA) has sparked a surge in exploration activity in the deepwater Niger Delta, particularly within the lesser explored shale diapir zone where...

We discuss the use of angle gathers in updating subsurface models within multi-parameter Full Waveform Inversion (FWI). The framework utilizes binned image gathers for modeling full pre stack data...

3D Seismic Foundation Models (SFMs) have been scaled to 1.8 billion parameters, pushing the boundaries of AI-driven seismic analysis. This work employs Vision Transformers (ViTs) augmented with...

High-density 3D seismic data over the Greater Endurance CO2 area have been processed by deploying a processing sequence to maximize resolution, including migration algorithms using primary...

A high-resolution seismic reprocessing project was conducted offshore Ghana. State-of-the-art processing sequence at 2 ms sampling and full waveform inversion based velocity model building enhanced...
