Recent refinement in 3D seismic
processing and interpretation developed by Total has highlighted a new fracture
pattern called polygons, pervasive over the whole sedimentary pile of the Abu
Dhabi fields, both onshore and offshore. In order to address the issues of
fracture characterization and their contribution to fluid flow specific
processing were developed and combined from the stack steps to the attribute
block definition. In tectonically precocious sedimentary basins and in gently
dipping sedimentary wedges the outcome from this processing usually highlights
the existence of right-angle joint patterns, comparable to what is classically
known in outcrops from the bedding scale to remote sensing scale (satellite).
