The play-opening giant discoveries of Baleine and Murene-1 (Calao) offshore Tano Basin have reinvigorated exploration in the Equatorial margin of Africa. The basin is geologically complex and has proven its unparalleled hydrocarbon potential. To further explore this basin, there is a need for high-end ...

We present a method for the quantitative assessment of the subsurface suitability of saline aquifer CO2 storage sites using a case study example from the Northern North Sea.

We describe how FWI Imaging results from existing, raw, conventional 3D seismic data, can be used as a rapidly available 3D alternative to dedicated site surveys or supplementary dataset to help improve understanding of the shallow subsurface.

The northern North Sea is a very active oil and gas exploration region, where several commercial discoveries have been made over recent years. The Lower Cretaceous sands within the Agat Formation is a reservoir play that has been targeted for decades. The quality and ...

In this paper, we show, first, how a high-resolution 65 Hz Vp model, obtained using Time-Lag FWI, can improve the imaging from the shallow to the deep. Similar improvements are then shown for PS data using a 30 Hz Vs model obtained from PS ...

This paper illustrates a robust methodology for achieving detailed mapping of sand injectites in the Greater Fram area using seismic attribute analysis and integrating machine learning techniques that are specifically targeted at injectites and fault prediction. Key to our methodology is the use of ...

A major challenge in the US Gulf of Mexico is transforming disparate public datasets into a quality-controlled database. CGG has successfully created and used the database for its Storage Play Quality Index (SPQI) carbon storage screening methodology and applied its latest imaging technologies to ...

In this paper, we present a high-resolution FWI case study from the foothills of the Southern Carpathians, in Romania. The input data was acquired in 2022, mostly with dynamite source, and designed for optimal subsurface wide azimuthal illumination. The varied rough terrain and the ...

Well drilling and abandonment work offshore Brunei is very challenging due to the presence of complex shallow geological features, such as corals, river channels, gas clouds/chimneys, and small faults. Therefore high-resolution seismic images, which can reveal those features, are desired to help avoid potential ...
