ABSTRACT

This paper describes a new class of Previous HitfaultNext Hit structure: the polygonal Previous HitfaultNext Hit system. This complex Previous HitfaultNext Hit system is composed of almost randomly oriented minor extensional faults organized in a polygonal network. The component faults are typically 500-1000 m long and have throws ranging from 10 to 100 m. They are closely spaced (200-400 m), and Previous HitfaultNext Hit mapping is possible only with 3-D seismic data.

The polygonal Previous HitfaultNext Hit system deforms Lower Tertiary shale sequences over a large part of the North Sea Basin and is restricted in extent to low-permeability facies in slope and basin plain regions. The faulted intervals are bounded above and below by completely undeformed sequences. These key observations are taken to suggest a genetic model in which the Previous HitfaultTop system formed through a compaction-related mechanism.
