Dithered slip‐sweep acquisition

A new technique for simultaneous vibroseis acquisition and processing, which is denominated dithered slip-sweep (DSS) acquisition, is here introduced. The objective of this technique is the high-productivity acquisition of data whose prestack quality enables applications such as amplitude variation with offset (AVO) and amplitude versus angle (AVA) analyses. This technique, which hinges on features of modern land acquisition systems such as large channel count and continuous recording, leads to acquisition scenarios with favorable conditions for prestack separability of simultaneously acquired data.
