We introduce a VSP tool combining three-component geophones with Distributed Acoustic Sensing to the surface for optimum image resolution near the target with a maximized lateral image aperture. However, combining VSP measurements made by geophones with DAS data, it is important to realize the difference between a DAS sensor and a three-component geophone, and also between a DAS sensor and a single-axis geophone. We explore these differences in order to create an optimum VSP image.
