Improved static corrections plus pre-stack interpretation improves the resolution of 2-D seismic data

Abstract

In the quest for improved resolution, the application of good statics routines is often ignored. Using coalfield seismic data, a model independent statics routine which uses the refraction events to align reflections is discussed with examples of its application. Good statics allows improved imaging of 2-D seismic reflection data, which then allows a novel work station method to produce pseudo-3-D volumes from 2-D pre-stack data. Hence subtle features, such as faults with small throws, can be well defined in the pre-stack domain, where they could not be readily observed on the conventional 2-D sections after stack.
