How to combine single hydrophone streamers with multi-component streamers in a 4D context: An offshore West Africa case study

In this paper, we demonstrate how conventional single hydrophone streamer data can be combined with dual sensor acquisition data to support the reservoir monitoring of a producing field in offshore West Africa. We describe innovative processing techniques for increasing the 4D resolution, and use case study examples to illustrate the methodology. The chosen processing approach intends to extend the signal bandwidth in a 3D and 4D sense. Improving the resolution of the 4D signal is essential for understanding the production of this complex reservoir, which is composed of turbiditic stacked channels.
