Improved Fault/Fracture Mapping through the Application of a Novel Dip estimation method

The objective is to assist seismic interpreters to efficiently map complex faulted areas with good details, for future fault and fracture modelling purposes. Accurate seismic dips are very important in this context, primarily because dips are the mandatory input to the curvature attribute, which is a generally accepted fault/fracture indicator. Therefore, accurate dip estimation becomes extremely important if we want to apply automated techniques for fault extraction. We will here present preliminary results of the application of a novel algorithm for the estimation of dips, which employs a set of global dip consistency constraints. The examples are from a carbonate reservoir in the Danish part of the North Sea.
