Abstract

Summary

As a part of the reservoir characterization and development plan for a North Sea oil field, a multi-measurement survey was acquired and processed in 2012 ( ). In order to assess the viability of such multi-measurement data for future time-lapse reservoir monitoring, a subset of the sail lines were repeated. This paper presents the results from the processing and analysis of this time-lapse experiment.

Recent advances in marine streamer acquisition and processing techniques have enabled the bandwidth restriction caused by the streamer ghost to be overcome to a greater or lesser degree. However a full 3D removal of the ghost requires measurement of the pressure wave-field and its vertical and crossline gradients. Having acquired such a dataset, we can select individual components for processing, and so compare different de-ghosting strategies and their effect on time-lapse attributes.
