On the 18th March 2016, Geophysical Services completed another in its successful series of High Resolution 3D “City Seismic” surveys in Singapore. The client is a renowned global engineering company, responsible for the construction of parts of the new Thomson Line MRT.
The seismic survey was carried out along Upper Thomson Road utilizing our i-Seis SIGMA data acquisition system in conjunction with our GISCO ESS100 Accelerated Weight Drop.
Parallel receiver and shot point lines were laid out which culminated in the acquisition of a 3D data cube, where data was acquired to 250+ metres below the surface, and where the Granite Rock-head was imaged after processing, in the form of a 3D Rock-head horizon model.
The receiver interval was 1 metre while the shot point interval was 2 metres apart, and data was acquired in autonomous data acquisition mode.
Geophysical Services Singapore Pte Ltd once again demonstrates that our "City Seismic" capabilities are up to the task in urban city environments where high volumes of vehicle and pedestrian traffic are an ever present challenge.
