The increase of productivity using simultaneous multiple sources also adds more complexity<br>in field acquisition and data processing. There are a number of key issues associated only<br>with High Fidelity Vibratory Seismic (HFVS1) technology. Understanding its pitfalls, one can<br>fully realize the potential benefits of this technology. We will demonstrate some of the pitfalls<br>by focusing on three main areas: the uniqueness of the phase-encoding scheme; the<br>importance of quality control of vibratory phases in the field; and pitfalls of inverting HFVS<br>data. We apply our best practice to a large 3D data set and illustrate the integration of field<br>acquisition and data processing, leading to high-resolution images of geological structures.
