NAM places GPS antennas in Groningen gas field area to monitor earthquakes

Printed below is an English translation of information published today by Nederlandse Aardolie Maatschappij BV (NAM), a joint venture between Royal Dutch Shell and ExxonMobil each owning a 50% share in the company responsible for the earthquake blighted Groningen Gas Field and consequential potential bill for untold billions in damages to effected residences.

NAM will install 30 GPS antennas in the coming weeks and around the Groningen gas field. The soil subsidence of the Groningen gas field is monitored with the GPS antennas. The measurement data are used for the risk studies in the context of the earthquakes.
Measurements at one location make it possible to immediately compare soil subsidence results. Possible measurement differences are discussed with, among other things, State Supervision of Mines (SSM).
Placing the GPS antennas is part of the measurements made in the framework of the so-called Study and Data Acquisition Plan of NAM, part of the 2016 Winningsplan.
The GPS units are placed wherever possible within the enclosure of existing mining sites. The units must operate without being affected by vibrations, such as caused by local traffic.
Read more on for more information about placing the 30 GPS antennas.
