North Rona Ridge 3D

Rich Azimuth Survey NW of Shetland

CGG has started acquisition of a high-density, rich-azimuth survey in the UK West Shetland Basin. The 3,600 sq km survey has received strong industry support, and has been designed in collaboration with major international oil companies. It focuses on delivering high-reolution seimic data in a prospective but underexplored area north-west of the Shetland Isles over the northern part of the Rona Ridge.

The survey is being acquired using an innovative acquisition geometry, deploying a source and streamer vessel with an additional source vessel. Both vessels are operating triple sources using simultaneous source technology. The configuration has been designed to image multiple targets, from shallow Tertiary and Cretaceous plays to complex fractured Devono-Carboniferous reservoirs, by undershooting the volcanic intrusions and other shallow unconformities present in the area.

Fast track PSDM data

The data will be processed in depth using CGG’s state-of-the art broadband imaging technology, including advanced de-blending and Full-Waveform Inversion velocity modeling. A fast-track PreSDM data set will be available in Q1 2019 and the final data in mid-2019.

The right data, in the right place, at the right time
