South West Hub CCS Project in Western Australia – Characterisation of a Greenfield Site

2014 Energy Procedia  
The South West Hub Project (SWH) is undergoing pre-feasibility assessment through a stage-gated program of data acquisition, managed currently by the Western Australia Department of Mines and Petroleum (WA DMP). Undergoing assessment for potential to store commercial quantities of CO 2 is an area of approximately 150 km 2 north of the town of Harvey in south west Western Australia. The emissions hub of Collie (~ 70 km to the SE) is the home to some likely users of the pore space if the site

In contrast to many potential storage projects, the area under investigation had undergone only limited geological evaluation prior to this project's initiation in 2007. Therefore a program of data acquisition has had to be developed and undertaken to populate an essentially greenfield site, to provide sufficient information to make informed decisions prior to proceeding through each stage gate. Activities to date have included: • A 2D seismic survey (2011) along local roads, which enabled the placement of a stratigraphic well. • The drilling of the Harvey-1 stratigraphic well (2012) to a depth of 2920.5 m TVDSS. • Research projects have then been commissioned to utilise these new materials and provide additional site characterisation. • A small scale 2D seismic survey (December, 2013) to aid in definition of acquisition parameters for a subsequent • 3D seismic survey conducted, taking in 115 km 2 of the approximate 150 km 2 area (February -March, 2014).
