Shearwater has been awarded a Distributed Acoustic Sensing (DAS) seismic program in the Stabroek Block, offshore Guyana, by ExxonMobil Guyana Limited (ExxonMobil).

The two-month scope of work comprises source‑only seismic acquisition in support of a baseline DAS reservoir surveillance survey over the Yellowtail development area. Shearwater has deployed the SW Empress in a triple source configuration, in direct continuation from a Multiclient project in South America where the vessel has been operating since November 2025.

“DAS programs may provide clients with specific insights into reservoir surveillance throughout a field’s life. Shearwater’s source technology, offshore execution experience, and flexible capacity enable vessels to switch between different modes to maximise vessel utilisation,” said CEO Irene Waage Basili.
