Aker BP Trials Distributed Acoustic Sensing Technology Offshore Norway

Aker BP is testing Distributed Acoustic Sensing (DAS) technology as a cost-effective alternative to ocean bottom seismic monitoring offshore Norway. DAS utilizes existing fiber optic cables on the seafloor to create a dense network of seismic sensors, enabling continuous seismic data collection without the need for extensive sensor installation. The company began R&D trials in 2022 at the Ula field, comparing DAS data with conventional seismic methods, and continued testing in 2023 with the Poseidon experiment to assess imaging capabilities.

Aker BP is evaluating Distributed Acoustic Sensing (DAS) technology as a potential alternative to traditional ocean bottom seismic (OBS) monitoring for offshore fields in Norway. The approach utilizes fiber optic cables on the seafloor to detect seismic activity by measuring microscopic deformations.

This method aims to reduce costs by eliminating the need to deploy numerous seabed sensors. The company initiated R&D trials in 2022 at the Ula field, where DAS data was compared to conventional 2D seismic data.

In 2023, the Poseidon experiment further explored the impact of cable response on subsurface imaging. The initiative responds to the increasing demand for efficient subsurface monitoring to support ongoing development and carbon storage initiatives in the region.
