On Top of Seismic Sampling - Benefits of High Resolution Source-OverSstreamer Acquisition

EAGE - European Association of Geoscientists and Engineers | Gordon Poole, Krzysztof Cichy, Ewa Kaszycka, Vetle Vinje, Nicolas Salaun © 2020 EAGE

Recent years have seen growing interest in improved shallow resolution images of the subsurface. This has led to ever more innovative acquisition approaches, each tailored to individual geological settings. We focus on a towed streamer acquisition in the Barents Sea which deployed five sources ...

Seismic processing with deep convolutional neural networks: opportunities and challenges

EAGE - European Association of Geoscientists and Engineers | Song Hou, Henning Hoeber © 2020 EAGE

Deep convolutional neural networks (DCNNs) are growing their popularity in seismic data processing due to their previous achievements in signal and image processing. In this paper, we explore the link between DCNN and seismic processing. We use two examples to demonstrate the potential of ...

Pore System Structure Assessment Using BSE-SEM Data

EAGE - European Association of Geoscientists and Engineers | Aurelie Bonin, Gareth Rogers © 2020 EAGE

This work investigates the potential of QEMSCAN in assessing the pore structure system. 23 carbonate and clastic samples are analysed using QEMSCAN, which shows a good assessment of the macropore system (pore larger than 10µm). It defines the macropore system volume and delivers pore ...

4D Ocean Bottom Node Decimation Study over the North Sea Golden Eagle Field

EAGE - European Association of Geoscientists and Engineers | Ivan Gregory, Zsofia Dobo, Farid Ebrahim, James Sinden (CGG) ; Peter McDonnell, Andrew J. S. Wilson (CNOOC International) © 2020 EAGE

Using a dense North Sea 4D dataset over the Golden Eagle field, we demonstrate the impact of OBN density on both the 3D and 4D seismic image by migrating progressively sparser node configurations. It is shown that 4D image quality is more sensitive to ...

Structurally Constrained Anisotropic Multi-Wave-Inversion Utilizing Machine Learning and Big Data on a Middle East OBC Project

EAGE - European Association of Geoscientists and Engineers | Vincent Prieux, Thomas Bardainne, Adrien Meffre, Herve Prigent (CGG) ; Franciscus Johannes Van Kleef, Muhammad Waqas, Lian Hou (ADNOC Offshore) © 2020 EAGE

Challenged by the presence of strong anisotropy and velocity reversal in the near-surface, we apply structurally constrained anisotropic Multi-Wave Inversion (MWI), over 1200 km2 of OBC data offshore Abu Dhabi. MWI aims at simultaneously inverting the P-wave first breaks (FB), the ground roll Dispersion ...

Upper Rhine Graben Deep Geothermal Reservoir Imaging

EAGE - European Association of Geoscientists and Engineers | Helene Toubiana, Guillaume Gigou, Jean-baptiste Mitschler, Nicolas Salaun © 2020 EAGE

Over the past 35 years, geothermal projects have been developed in Upper Rhine Graben (URG) to exploit deep geothermal energy. Below a couple of kilometers of sediment, the deep target consists of granitic basement, highly fractured and hydro-thermally altered, having a high reservoir potential ...

Optimal Transport Full Waveform Inversion - Applications

EAGE - European Association of Geoscientists and Engineers | Diego Carotti, Olivier Hermant, Sylvain Masclet, Mathieu Reinier, Jeremie Messud, Anna Sedova, Gilles Lambare © 2020 EAGE

While full waveform inversion (FWI) has imposed itself as a privileged velocity model building tool in areas investigated by diving waves, it is still penalized by its sensitivity to cycle skipping. Among the various strategies proposed to mitigate the problem, optimal transport (OT) FWI ...

Capturing the Value of Source-Over-Streamer Acquisition for Velocity Model Building at Barents Sea

EAGE - European Association of Geoscientists and Engineers | Nicolas Salaun, Mathieu Reinier, Andrew Wright, Guillaume Henin, Guillaume Gigou © 2020 EAGE

The source-over-streamer configuration has been designed to improve pre-processing of the seismic data leading to high-resolution imaging. It also leads to new residual moveout information, unique in its high quality and density. By adding a front source to the original design, long offset information ...
