Tiexing received his PhD in Geophysics in 2020 and began his professional career in the energy industry. Currently, he works as a Project Research Geophysicist at Shearwater R&D UK. His work focuses on cutting-edge marine vibroseis processing technology,
particularly in signature estimation and deconvolution.
He is also actively involved in research related to deep learning and
ultra-high-resolution seismic data processing and interpolation.

To meet the energy transition goal and the demand for environmentally friendly sources, we have been developing more advanced marine vibroseis technology and its associated data processing methods. Recently, we conducted an alpha test in the North Sea, acquiring a 3D swath of data using a single marine vibrator (MV), along with several test lines using a two-MV source array covering a frequency range of 3-150Hz, and two ultra-low-frequency single-MV lines covering 1-8Hz up to an 18km offset. The processing results not only show quality comparable to traditional airgun arrays but also highlight the MVs’ ability to generate signals down to 1.5Hz over large offsets. These findings demonstrate that MVs can act as a sustainable alternative to traditional sources for large-scale broadband acquisition. Moreover, MVs hold significant potential for enhancing 4D seismic monitoring, as they provide precise control over their emitted signal.
