April 15, 2015 – EAGE 2015 Boot Camp

The European Association of Geoscientists and Engineers (EAGE) annual Geophysics Boot Camp provides students and early career professionals with valuable field experience using geophysical instruments. Sensors & Software provides a pulseEKKO PRO GPR system with 250 and 500 MHz transducers for the field camp.

Under the guidance of Dr. Adam Booth, 60 participantsfrom various universities and companies performed GPR surveys to map near-surface infrastructure around Germany’s Emlichheim oilfield (operated by the company Wintershall). The data were also used in support of archaeological initiatives in the local area. Delineating buried infrastructure plays a critical role in de-risking the seismic operations. Wintershall had specified that no seismic sources could be placed within 10 meters of any of their subsurface pipes. GPR surveys confirmed that exclusion zones had been correctly marked on the road surface. Participants were therefore undertaking a relevant and real-time civil engineering survey as part of the camp!

The GPR line collected showed the classic hyperbolic response from a pipe, specifically two steel gas pipes, imaged with a 500 MHz system. Archaeological surveys were conducted in the grounds of Stiftung Kloster Frenswegen, originally a 13th Century monastery close to the town of Nordhorn. GPR surveys using 250 MHz and 500 MHz transducers revealed evidence of earlier archaeology, and the circular features cut into the soil at the site are potentially Saxon storage pits termed ‘grubenhäuser’.
