North Rona Ridge 3D

Rich Azimuth Survey NW of Shetland

CGG high-density, rich-azimuth survey in the UK West Shetland Basin includes coverage of the OGA 32nd round blocks. The innovative 3,600 sq km survey was designed in collaboration with major international oil companies and focuses on delivering high-resolution seismic data in a prospective but under-explored area north-west of the Shetland Isles over the northern part of the Rona Ridge.

The survey was acquired using an innovative rich azimuth acquisition geometry to maximize the illumination of several subsurface targets, from shallow Tertiary and Cretaceous plays to complex fractured Devono-Carboniferous reservoirs masked by volcanic intrusions at varied intervals that add to the challenges posed by shallow unconformities in the area.

Final PSDM data

The subsurface was imaging in depth using a selection of specialist solutions from CGG’s state-of-the art broadband imaging technology toolbox, including advanced source de-blending, wave equation demultiple, TL-FWI multi-layer velocity modeling, dedicated AVO products, RTM and Q-least-squares imaging. Final data are now available for licensing.
