Spectrum says there has been a “dramatic improvement” in the sub-basalt imaging of its Offshore Iceland multi-client survey as a result of seismic data reprocessing.  

The data, comprising 5237km of 2D seismic shot in Icelandic and Norwegian waters, includes the Jan Mayen ridge.  

The first licensing round in the Norway-Iceland Jan Mayen Agreement Area opened last week and includes the Northern Dreki area of Iceland.  

The company said that by using Pre-Stack Time Migration (PSTM) and Surface Related Multiple Elimination (SRME) with Radon applied, combined with Spectrum's bespoke TLC techniques, the geoscientists achieved better multiple attenuation and improved the imaging of sub-basalt reflectors.  

The offshore Iceland survey's Mesozoic geology is now much more clearly defined.  

“Although little prospect information is known about the area, a well-documented correlation of source and reservoir rocks in adjacent Norwegian and Greenland margins give promising indications of hydrocarbons. Similar geological development could be reasonably assumed for the Icelandic prospects,” Spectrum said in a statement.
