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...
This paper presents an enhanced binning strategy that includes selections of both the best (primary or rank 1) and second-best (secondary or rank2) pairs of ∆SrcRcv. We then use regularization and...
The Usan field, located offshore Nigeria, has a well established history of deriving significant value from 4D seismic analysis. The recent 2023 Monitor (M3) survey was processed alongside the...
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...
