RockWave Reprocessing Multi-Client 2D for Geoex MCG in Norway

Basin rejuvenation starts with seeing deeper

The recent announcement from Geoex MCG on the reprocessing of the RDI MC2D dataset in the Norwegian Sea highlights a simple point:

If you want to unlock more from a basin, you need to see deeper into it.

Why this dataset matters

The Regional Deep Imaging (RDI) MC2D dataset is built for regional understanding at depth.

With long offsets and extended record lengths, it images the full sedimentary section and into basement. That is critical in areas like the Norwegian Sea, where key uncertainties sit deep in the system and are often poorly constrained.

Its strength lies in:

• Regional consistency

• Deep penetration

• Coverage across large areas and geological domains

This is where 2D remains highly effective.

Why 2D still matters

For basin-scale work, long-offset 2D remains the right tool.

It provides:

• Deep imaging capability

• Regional coverage across large areas

• A consistent framework for interpretation

That combination is essential when building an understanding of basin evolution before focusing on smaller-scale detail.

A broader perspective from RockWave

RockWave’s foundations are in oil & gas seismic processing, particularly with large, regional multi-client 2D and 3D datasets. We’ve spent a significant part of our careers working with data that spans entire continental shelves, tying together different vintages, acquisition styles, and geological settings into something coherent and usable.

These datasets often move from deep sedimentary basins into structurally complex areas and volcanic provinces, where imaging becomes uncertain and deeper geology is difficult to resolve. Extracting value requires processing sequences that are consistent at scale and robust enough to handle changing geology without introducing interpretation bias. Thorough testing and tight communication with those possessing a comprehensive knowledge of such settings is essential to achieving goals throughout these typically long-duration projects.

That experience shapes how we approach projects today not just for conventional/exploration seismic, but also for extremely/ultra high resolution projects that cover equally large expanses when the Factor 50 (Woodburn, Monk, 2024) is taken into consideration.

RockWave’s focus on this project is: deliver seismic you can trust. Data that is consistent, explainable, and reliable enough to support geological decisions at regional scale.

Reprocessing and reinterpretation

Testing on the Geoex MCG’s RDI MC2D dataset has proved that modern reprocessing approaches to deghost, designature, demultiple, and velocity model building can lead to:

• Sharper imaging of Palaeozoic and Mesozoic stratigraphy

• Improved definition of Top Basement

• Better visibility of deep structure

With its depth penetration and regional continuity, the dataset will support a clearer understanding of source rock maturation and reservoir distribution across the Norwegian Sea.

What this delivers

The key step will be reinterpretation and that will be for licensees of this multi-client seismic dataset to undertake. Improved data changes how the basin is understood, often challenging earlier assumptions and expected to lead into practical and measurable outcomes:

• More robust charge modelling from clearer imaging of source intervals and migration pathways

• Enhanced reservoir prediction through improved stratigraphic and structural definition

• Reduced risk during acreage evaluation by increasing confidence in regional interpretation

This is where regional datasets create value. They provide the framework that underpins exploration decisions.

Why this matters now

Reprocessing projects like Geoex MCG’s RDI MC2D underscore that seismic data’s value isn’t fixed – it can be improved. In a market of mature basins, evolving energy projects (CCUS, hydrogen) and frequent licensing rounds, maximising existing datasets is both economically wise and technically enabling. High-quality regional frameworks speed up screening and reduce drill risk, whether for traditional hydrocarbons or emerging plays. In this context, fine-tuning the processing on long-offset 2D is a strategic move: it creates new knowledge assets that challenge our often long-held preconceptions.
