With the implementation of smart fields where sensors play a major role for measurement and control of the production process, continuous monitoring becomes increasingly important. In wells it is common practice to constantly monitor parameters like flow, pressure, and temperature. For imaging techniques like (active) seismics so far monitoring has only been applied in a time lapse manner with a repetition interval generally in the order of a year, not in a continuous way. The Vallhall field probably comes closest to continuous monitoring with permanently installed ocean bottom cables (OBC) and repeated surveys in the order of months.

The main challenge with permanent seismic monitoring is not so much the technical feasibility, but more the data transfer and processing of the vast amounts of acquired data. TNO together with the TU-Delft, KNMI and ASTRON have started to implement a seismic monitoring network in the Netherlands using an ultra-fast digital optical fibre network linked to one of the most powerful computers in the world, the IBM BlueGene/L system. Data can be sent to this computer at speeds up to 20 Tera-bits/second. Currently passive seismic data is constantly acquired at Exloo, the first out of 50 test fields to be installed in the next year.

Besides seismics, the network and the ICT infrastructure make it possible to combine all sorts of observations from the natural environment, infrastructure and processes anywhere and any time. This paper will give an overview of the first results of the incoming data and a description of the ICT infrastructure and network. Furthermore a view will be given on future applications.
