Bringing high-density acquisition to the Transition Zone

Recording seismic in Transition Zone (TZ) environments is both operationally and technically challenging, often leading to complex and expensive field operations, and compromised data quality when not approached correctly.

High noise levels and significant near-surface variability demand much denser receiver sampling - but achieving this economically has long been a barrier.

One of the biggest challenges is data timing, as GNSS signals are weakened or blocked in shallow water and traditional solutions used to deal with this come with trade-offs:

🔹 Cable systems – reliable timing but operationally cumbersome
🔹 OBN's – advanced clock technology but high unit costs

In November 2025, STRYDE's Chief Technical Officer, Nicolas Goujon, addressed these challenges at the EAGE (European Association of Geoscientists and Engineers) Seabed Seismic Workshop in Bahrain during a presentation he delivered titled "Bringing High-Density Acquisition to the Transition Zone".

Nicolas presented how low-cost clock technologies combined with machine learning algorithms, enable affordable, high-density TZ acquisition using derivatives of low-cost land seismic nodes.

His research demonstrates a promising pathway toward making high-quality TZ data both achievable and economical.
