Accurate Detection of Reservoir Boundaries Using Electromagnetic Attributes and Inversion of Marine CSEM Data

In this paper we introduce a new electromagnetic attribute that can be helpful for detecting properly the borders of resistive layers, such as a reservoir, with an accuracy that depends only on the receiver spacing. After using that attribute for identifying the spatial distribution of the resistive layer(s), inversion is applied for a proper characterization in terms of resistivity inside the layer itself. 3-D Synthetic tests and applications to real data will be discussed.
