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 proves up.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). 5042Linda Stalker et al. / Energy Procedia 63 ( 2014 ) 5041 -5050 Results from these activities so far have not presented the project with any "show-stoppers". The key intervals of interest, the Yalgorup and Wonnerup members of the Triassic Lesueur Formation show suitable rock properties for purposes of carbon storage. Fault identification and their modeled transmissivity do not indicate extensive compartmentalization in the storage region. Whilst the key to this project is residual trapping (Wonnerup as the primary containment interval and Yalgorup as the secondary containment interval) there is improved evidence to suggest the presence of potential baffles and seals in the area to retain the CO 2 .As at mid-2014, the plan forward will include: • 3D seismic processing, interpretation and the building of a new geological model (underway mid -2014).• Drilling of three shallow wells to better characterise the upper layers (2014 -2015).• Flow testing of one of those three wells to better assess the potential baffles (2015).• Drilling of a deeper well(s) to characterise the reservoir properties off the Harvey Ridge Structure (late 2015).• Related research activities using the new materials generated from the upcoming well drilling and testing program.The recently acquired 3D seismic survey is already providing valuable information to constrain the main formations distribution and aiding in the location of the likely areas for further data acquisition. Complementary research projects are ongoing to facilitate the valuation of the site with the aim of reducing risk and unc...

“…The SWH proponent has been the Western Australian Department of Mines, Industry Regulation and Safety (DMIRS) since the earliest data gathering commenced in the mid-2000s. The investigation of a greenfield area in the Southern Perth Basin for potential commercial scale storage for emitters in the Perth and southwest region resulted in drilling of four wells, Harvey-1, -2, -3 and -4 [1] & [2] (Figure 1). The wells were located after a series of seismic surveys were conducted to understand the geology and structure in the area of interest.…”

Lessons Learned: The First In-Situ Laboratory Fault Injection Test

The CSIRO In-Situ Laboratory has been a world first injection of CO2 into a large faulted zone at depth. A total of 38 tonnes of CO2 was injected into the F10 fault zone at approximately 330 m depth and the process monitored in detail. The site uses a well, Harvey-2, in SW Western Australia (the South West Hub CCS Project area). The top 400 m section of Harvey-2 was available for injection and instrumentation. An observation well, ISL OB-1 (400 m depth) was drilled 7 m to the north east of Harvey-2. ISL OB-1 well was cased with fibreglass to provide greater monitoring options. The CSIRO In-Situ Laboratory was designed to integrate existing facilities and infrastructure from the South West Hub CCS Project managed by the West Australian Department of Mines, Industry Regulation and Safety. While new equipment was deployed for this specific project, the site facilities were complemented by a range of mobile deployable equipment from the National Geosequestration Laboratory (NGL). The geology of the area investigated poses interesting challenges: a large fault (F10) is estimated to have up to 1000 m throw overall, the presence of packages of paleosols rather than a contiguous mudstone seal, and a 1500 m vertical thickness of Triassic sandstone as the potential commercial storage interval. This unique site provides abundant opportunities for testing more challenging geological environments for carbon storage than at other sites. While details of this first project are described elsewhere, lessons were learned during the development and execution of the project. A rigorous risk register was developed to manage project risk, but not all events encountered were foreseen. This paper describes some of the challenges encountered and the team's response. Relocation of the project site due to changes in landholder ownership) and other sensitivities resulted in the need for rapid replanning of activities at short notice resulting in the development of the site at Harvey-2. The relocation allowed other research questions to be addressed through new activities, such as the ability to consider a shallow/controlled release experiment in an extensive fault zone, but this replanning did cause some timing stress. The first test at the In-Situ Laboratory was reconfigured to address some of those knowledge gaps that shallow/controlled release experiments had yet to address. Novel approaches to drilling and completing the monitoring well also threw up unanticipated difficulties. Loss of containment from the wellbore also posed significant challenges, and the team's response to this unintended release of gas and water from the monitoring well at the

“…The In-Situ Laboratory Project , entails a configuration of wells at approximately 400 m depth for monitoring the release of a small volume of CO2 for testing purposes in a fault zone (Figure 1) at the South West Hub CCS Flagship project (SW Hub) in Western Australia. The SW Hub is a 'greenfield' investigation site south of Perth, which had little pre-existing subsurface data available to perform geological site characterisation (Sharma et al, 2014). Thus acquiring geoscience data for the site has been a focused effort during the past seven years.…”
