The Sonardyne acoustic subsea Data Logger has a track record of more than 25 years of successful installations and the current generation includes Sonardyne’s wideband acoustic technology and a design which allows the subsea unit to be deployed and retrieved by ROV and for large volumes of logged data to be rapidly and accurately retrieved at the surface.

When combined with the feature of ROV portability, the system is the ideal solution for initial well appraisal, where frequent downhole pressure and temperature readings need to be logged over a period of a few weeks. However, the new system is equally suitable for long-term deployments where it may remain installed on a wellhead, logging data for several years without intervention.
