Temprei - A Robotized, Contactless, Multi-component Seismic-receiver System

Statoil has developed a new multicomponent seismic sensor (“Temprei camera”) to increase acquisition efficiency, flexibility and access to complex sites like offshore installations. Acquisition can be improved, because the contactless sensor does not have to rest on the surface, nor does it have to stop while recording.

The Temprei camera is at the moment designed as a “host instrument” for flexible AUV-based offshore operations, but might also be utilized onshore or in flight. We explain the camera concept, the development and testing of the Temprei camera from optical table, via water laboratory to a fjord test in an AUV (REMUS 100) - mission operated by NTNU. Finally we describe a possible first application of the Temprei camera to characterize shallow geology for safety and increased oil recovery.
