Enhanced 3D Imaging from 2D Seismic Data and its Application to Surveys in the North Sea

We have developed an enhanced methodology to create a 3D seismic migration volume from a set of 2D seismic lines. The key challenge is to interpolate coarsely spaced 2D seismic lines into a dense 3D seismic volume before performing a post-stack migration. Building a geologic time model which essentially consists of a set of geological time horizons and using them to guide the interpolation is a practical approach to address the coarse sampling issue. Successful application of enhanced methodology to a data example from the North Sea demonstrates its effectiveness.
