This is a Joint Research Project of a seismic test survey using dynamite as a seismic source in the Gippsland Basin between South Australian Gas Company (SAGASCO) and Geoscience Australia. This survey wad conducted by using the GA Sercel SN368 seismic 120 channel data acquisition system, two drilling rigs and seismic crew. The primary objective of the seismic test survey was to test whether by using dynamite as the seismic energy source, seismic reflection events could be recorded from geological horizons below the base of the Latrobe Valley Group. Processing of the seismic data revealed that using explosives as a seismic source also had difficulty in resolving seismic reflection events below the Labtrobe Valley Group sediments. In places multiple reflection events due to the coal beds within the Latrobe Valley Group are intermixed with primary reflections making interpretation of deeper reflection events difficult or impossible. However long offsets recordings highlighted a significant first break refraction event at far offset distances, which from preliminary interpretations is related to the base of the Latrobe Valley Group or top of Strzelecki Group. To resolve the thickness of Strzelecki Group sediments, the recording of first break refraction events using long offset walkaway spreads (offsets in the 6 to 8 km range) maybe a technique to test in future seismic surveys.
