Two major seismic surveys were conducted in the Harvey area on behalf of the South West Hub:
A 2D Seismic Survey along 106 kilometres of roadway in an area north-west of Harvey town site, including Riverdale Road, was conducted in March 2011 prior to any stratigraphic well drilling.
A 3D Seismic Survey covering 116 square kilometres (km2) of the target reservoir area was conducted in 2014.
Smaller, Nested Surveys, were conducted by Curtin University around three of the wells. These were undertaken to provide further data and establish the complexity of shallow structures.
