Core samples and data were collected on behalf of the South West Hub from four stratigraphic wells drilled in Harvey.
One deep well: GSWA Harvey 1 – was drilled to a depth of 2945 metres between February and March 2012.
Three shallow wells: DMP Harvey 2 was drilled to 1350.2 metres, DMP Harvey 3 to 1550.2 metres and DMP Harvey 4 to 1802 metres, between December 2014 and June 2015.
Samples from more than two kilometres of core were used to measure porosity and permeability, and to run injection tests using brine and then CO2. This core is stored at the Perth Core Library.
