The target of the proposed 3-D study is the top of clay layer that serves as a structural trap for DNAPL. The plot below shows clay depth estimates from the interpretation of well log data (triangles). As this plot shows, we have substantial information for targeting our 3-D study.

The purpose of the proposed 3-D seismic study is to better constrain the structure of the channel, especially in its northern part, near seismic line 3.
