Over 650,000 line kilometres of legacy seismic data exists onshore Australia, acquired since the 1960’s for petroleum exploration and more recently for deeper crustal studies.   Much of the original processing did not focus on imaging features of interest for mineral explorers. 

Searcher has been reprocessing key lines with a mineral exploration mindset which is enabling considerable new insights for ongoing exploration.

The 2025 reprocessing of the deep-crustal 2D Line 23GA-NT2 in the Northern Territory provides enhanced shallow imaging within the MesoProterozoic Birrindudu Basin, as well as confirming deeper crustal architecture of the underlying PalaeoProterozoic Tanami Region.

The reprocessing by Realtimeseismic (RTS) was focussed on the upper 3 seconds with the objective to provide better definition of faults, structures and steep events.
