Advanced geophysical data analysis at Harvey-1: storage site characterization and stability assessment. Final report
25th March 2013
Topic(s): Carbon capture use and storage (CCUS), CO2 storage
One of the first planned onshore commercial-scale CO2 geosequestration projects in Australia is at the South West Hub site, approximately 150 km south of Perth, WA. As part of the detailed characterisation work at the site, the new Harvey-1 Data Well was drilled in early 2012 to approximately 3km depth, penetrating the Lower Lesueur formation which is the main CO2 injection target. Its purpose was to obtain rock core samples and other physical data to reduce gaps in geological knowledge and help assess the suitability of the formation for CO2 storage. Drilling of the Harvey-1 Data Well has provided several geophysical data sets, including log data and zero-offset vertical seismic profiling (ZVSP) data. In addition, a set of 2D seismic lines was acquired in 2011, with basic image processing performed by a contractor. The main goal of this ANLEC research project is to apply a range of advanced data analysis techniques, developed by (or available to) WA:ERA researchers, to the geophysical datasets acquired at the Harvey-1 data well and the recently acquired 2D seismic data, in order to extract higher value from the data, reduce risk in the SW Hub CCS project through improved storage site characterisation, and guide optimal acquisition and processing parameters for future geophysical surveys.
