Abstract
Standard seismic processing and controlled stacking of mode converted energy has proven successful in sub-basalt imaging (most recently Emsley et al., 1998; Longshaw et al., 1998). There is however, widespread scepticism about the nature of the imaged reflectors (sub-basalt primary vs. multiple). In this paper, we present new results from migration of long-offset data (12.5 km) that were acquired in 1996 by Phillips Petroleum over Tertiary flood basalt in the Rockall Trough, NW of the Hebrides.
