Abstract This study presents an integrated seismic, well and core-based analysis of the Maureen Formation in Central Graben North Sea. Facies reveals that it is possible to divide sandstones into amalgamated, sand- mud-prone divisions, but related chalk facies are complex imply a range depositional processes including pelagic fallout, debris flows turbidity currents. These deposits have impact on interpretation amplitude-based seismic attribute volumes. Detailed petrophysical mapping, supported by analysis, were deposited distinct western eastern fairways controlled relict Mesozoic rift topography (although offset stacking important intragraben process). The spatial extent similar overlying Sele Lista formations suggests broad controls sediment routing same throughout Lower Palaeogene. Other similarities between these systems include role sandstone texture controlling reservoir quality heterolithic nature means porosities permeabilities lower). A pattern intraformational progradation late-stage backstepping units likely sea-level variability.
