permeability documented by the seven production
tests. Beneath the Volgian unconformity there is Middle to Upper Jurassic estuarine to fluvial sand
sequences with good reservoir qualities. Beneath the
base Middle Jurassic unconformity there are marine to
continental Lower Jurassic sands of very good quality.
Zechstein karstified limestone and dolomite are also
present as reservoirs.
The Luno 2 discovery is a Late Triassic/Jurassic
inlier basin with reservoirs in fluvial facies sandstones.
This oil discovery is sourced from the Heather/
Draupne formations.
The Volgian inversion on the Haugaland High is
reflected regionally on the NCS and formed the Mid
North Sea High, Utsira High, Tampen High, Manet
High, Frøya High, Nordland Ridge, Loppa High and
Fedinsky High. Hence analogue plays have and will be
found around these highs. This demonstrates the
importance of having a regional geological perspective in formulating efficient exploration strategies.
Renewed exploration of the Barents Sea resulted in
the discoveries of the Johan Castberg field in 2011 and
the Gohta and the Wisting discoveries in 2013
(Fig. 26.15). Common for all these light oil
discoveries is ongoing active oil migration that
compensates for leakage of oil during the glaciation
periods. The indication of this process has been there
for a long time, but the possibilities were shadowed for
by the ruling view that focused on the leakage problem
and not on the active ongoing petroleum migration
which has been documented by sampling. The
reservoirs are Late Triassic to Middle Jurassic
except for Gotha with karstified Permian carbonate
reservoirs.
The new discoveries on the NCS related to both old
and new play concepts since 2003 demonstrate that the
exploration process should always be open in relation
to which parameters are necessary. The seed for new
knowledge will always be outside the bandwidth of
preconceived ideas and the truth can never be voted on
by majority or size. Diversity and not more of the same
is needed in generative knowledge creation. The following wording of Piet Hein is a good guidance for
exploration; “To know what thou knowest not is in
essence omniscience”.
