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...

2D and 3D seismic data from frontier offshore basins around Africa has been subjected to relative extended elastic impedance inversion (rEEI) to screen for AVO anomalies and to identify large,...

The study addresses the challenges of 4D seismic inversion in the mature Albacora Leste field, Campos Basin, Brazil, a complex deepwater reservoir with stacked turbiditic deposits. Using a 2005...

Field data recorded by a new rotational 6-degree-of-freedom sensor have been analysed. Rotational components were used for evaluating the polarization vector of the seismic events in the data and a...

In seismic imaging, reducing the turnaround time of imaging projects is essential. Although advances in computer power have shortened the processing time of the standard marine sequence, this...
