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