IS-JMR-01 & WI-JMR-08 - Offshore 2D Surveys
CGGVeritas has acquired two long-offset multi-client 2D surveys in the Dreki area, Jan Mayen
Ridge, offshore Iceland. These surveys have been specifically designed to provide explorers with
a powerful tool to further improve imaging below the basalt.
The Jan Mayen Ridge is a microcontinent on the North Atlantic Margin
between Greenland and Norway. The southern part of the Ridge belongs
to Iceland and the northern part to Norway.
71°N
It is comparable geologically to adjacent basins within the North
Atlantic Margin-Møre, Vøring, Greenland and Shetland basins, some of
which have been the focus of successful petroleum exploration.
Petroleum System
The presence of layered basalt within the Jan Mayen Ridge and its
adjoining basins makes imaging difficult, which means that high-quality
seismic will be a useful tool for explorers:
69°N
•Seismic data indicates the possibility of pre-rift sedimentary sequences
below the basaltic complex. These pre-rift sediments could offer a
potential source of hydrocarbon
•We have identified potential hydrocarbon play elements within the
rifted margin. These include potential rift-related fluvial/shallow
marine reservoirs within tilted fault blocks, continental and marine
source rocks and possible sealing facies
67°N
•On the passive volcanic margin, possible submarine fans have been
identified which, if sand-rich and stratigraphically trapped, could offer
significant potential
•Bright spots on seismic as well as pockmarks on the sea floor indicate
the possible presence of hydrocarbons within the basin

2009 Reprocessing
CGGVeritas has acquired over 3,600 km of 2D long-offset seismic data
over the Jan Mayen Ridge, offshore Iceland.
The current dataset was acquired in two phases:
•Phase 1 (IS-JMR-01), consisting of 2,765 km of 10-km long-offset 2D
data acquired in 2001
•Phase 2 (IS-JMR-08), consisting of 859 km of 10.05 km of long-offset
2D in-fill lines acquired in 2008
In 2009, CGGVeritas reprocessed 1,760 km of key lines from the 2001
survey, applying the latest techniques such as Fully Ray-Traced Kirchhoff
Prestack Time Migration.
The reprocessed dataset shows significant improvement in fault plane
resolution, multiple removal and noise attenuation, enabling better
imaging of structures and stratigraphy. This has led to an improved
understanding of the geology and hydrocarbon potential of the Jan
Mayen area.
The reprocessing provides an overall modern and high-quality dataset
from this highly underexplored area of the North Atlantic margin.
