GSL Completes High Resolution 2D City Seismic along Kranji Road, Singapore

Survey line layout along Kranji Road in Singapore.

Geophysical Services Singapore Pte Ltd completed a high resolution 2D city seismic survey in Singapore along Kranji Road on the 8th November 2015 by utilizing Seismic Source Company's iSeis SIGMA system and GISCO Geo's Electronic Seismic Source 100 Accelerated Weight Drop mounted onto a specialised cart.

The single 2D line comprised of 157 metres of active channels with a target depth of 30 metres below the ground surface to identify the bedrock (rock grade GIII or GIV) or any potentially large boulders. The receiver group interval was spaced 1 metre apart while the source shot point interval was 2 metres apart.

Despite encountering an unexpected and challenging high volume of traffic on the road during the survey as well as low light conditions; with proper care in safety, coordination and traffic management, Geophysical Services Singapore Pte Ltd was able prove that our "City Seismic" capabilities are up to the task by producing high quality data that met the industry and client's standard.
