oa How could the CSEM experiment be improved ?

In conventional marine CSEM for hydrocarbon exploration, the source is towed behind a vessel without active steering, and a set of receivers are positioned on the seafloor. Traditionally, the receivers have been positioned along the towline which leads to the socalled inline source-receiver geometry. In the last few years, the industry has moved towards using 3D receiver grids. A major advantage with 3D is that the subsurface is explored with the inline source-receiver geometry in several directions. Another added value is that one also gets additional broadside data in some of the directions (directions where the source can be decomposed into two components).
