A series of regional basin-modelling studies performed in the Norwegian sector of the northern North Sea through the last 10 years is reviewed to show how excessive rework is avoided by taking advantage of previously completed studies. The modelling approach investigated features fully quantitative modelling of basin processes that control the petroleum system, i.e., processes relevant to maturation of source rocks, expulsion from source rocks into the carrier rocks, secondary migration within the carrier rock and fill-spill-leakage behaviour of traps. The ability to take advantage of improvements in computer technology and advancements in integration represents major steps forward in the 10-year evolution, but, first and foremost, the opportunity to reuse and continuously update an existing basin model has been the key to success of the methodology. The paper discusses weaknesses and strengths of the approach. It also addresses the sort of conclusions that can be drawn from such work and presents some historical examples from Norwegian Blocks 30/8 and 30/12 and East of Troll.
