Welcome To MultiRift Project Website

The main aim of this project is to develop a fundamental understanding of how pre-existing structures in both basement and cover influence the evolution of normal faults and normal fault populations on rifted margins. We will use this understanding to analyse the geomorphological evolution of rifts and the impact this has on erosion, sediment transport pathways and the overall evolution of syn-rift depositional systems. Our main aim will be achieved through a series of specific objectives.

• To investigate how pre-existing basement and cover structures influence the nucleation, growth, interaction and linkage of normal fault segments and their organisation and evolution within multi-phase rift basins.

• To establish how pre-existing structures influence the evolution of rift basins and use this analysis to understand the controls on rift topography, sediment sources, major sediment transport pathways and depositional systems in multi-phase rifts.

• To quantify the effects of erosion, deposition and mass redistribution at the Earth's surface on fault evolution and rift basin morphology where pre-existing structures exert a strong control on fault development.

The results of this study will be used by the petroleum industry to: a) understand more clearly the controls on, and variability of, structural traps related to normal faulting, and b) develop models for subtle syn-rift plays. Thus the project will contribute to reducing exploration risk and increasing the sophistication of syn-rift reservoir models. Although we focus on the Norwegian part of the northern North Sea, the generic understanding of normal fault growth and the associated evolution of syn-rift sedimentary systems will be applicable along the Norwegian continental shelf, where syn-rift structures and stratigraphy are economically significant (e.g. Vøring and More margins, Haltenbanken), and to rifted margins world-wide.
