Abstract
B025 A Southern North Sea Multi-Survey preSDM 1 A. G. CAMPBELL 1 E.EVANS 2 .D.JUDD 2 I. F.JONES 2 S.ELAM 1 Abstract Exploration in the Southern North Sea using conventional imaging techniques is hampered by complexities in the Mesozoic overburden and the Zechstein evaporites with dolomitic rafting overlying potential targets. 3D preSDM imaging has come into widespread use in recent years in an attempt to resolve such problems. Here we present case history from the ConocoPhillips acreage over block 49/14a where a four survey merge covering some 430sq.km (figure 1) was reprocessed to yield a coherent single input volume for
