CLEAN COAL DAY JAPAN 2015 INTERNATIONAL SYMPOSIUM 9 SEPTEMBER 2015 1
A DAY IN THE LIFE OF A CARBON ATOM STARRING: ADOM 2
Japanese Weekend School – Perth 8 August 2015 3
CURRENT STATUS • Commercial and policy settings in Western Australia and Australia have changed since 2010; • This presentation will focus on what activities involving site characterisation in the South West of Western Australia; • The area is close to major industries such as power stations and alumina refineries; • Collie coal is a domestic market; • Collie coal has enormous potential for gasification; • The Gorgon project on Barrow Island, in the North West will commence Carbon Storage in mid 2016 – world’s largest CCS project 4
DEPARTMENT OF MINES AND PETROLEUM Will manage early stage activity including the provision of detailed geological information, establishment of research capability, acquisition of data and core and establishment of the community engagement process 5
STORAGE PORTFOLIO 6
LOCATION • In the heart of South West industry • Does not compete with potable water • 125 land owners; next to town 7
Screening Studies : 1998 – 2007 • CO2CRC study (2002-2005) looked closer at this issue. • GEODISC (1998 – 2000) studies considered containment as a high • Lightly explored: limited well and risk. seismic data • Lack of the thick shallow • Collie Basin screened out aquifer (Yarragadee) • Harvey Ridge identified as a potential area of interest • Structural geometry VLAMING VLAMING VLAMING VLAMING VLAMING VLAMING VLAMING VLAMING VLAMING VLAMING VLAMING VLAMING System System System System System System System System System System System System SUB-BASIN SUB-BASIN SUB-BASIN SUB-BASIN SUB-BASIN SUB-BASIN SUB-BASIN SUB-BASIN SUB-BASIN SUB-BASIN SUB-BASIN SUB-BASIN • Thick marginal MANDURAH MANDURAH MANDURAH MANDURAH MANDURAH MANDURAH MANDURAH MANDURAH MANDURAH MANDURAH MANDURAH MANDURAH TERRACE TERRACE TERRACE TERRACE TERRACE TERRACE TERRACE TERRACE TERRACE TERRACE TERRACE TERRACE High High High High High High High High High High High High PERTH PERTH PERTH PERTH PERTH PERTH PERTH PERTH PERTH PERTH PERTH PERTH seal/reservoir Roe High Roe High Roe High Roe High Roe High Roe High Roe High Roe High Roe High Roe High Roe High Roe High Fault Fault Fault Fault Fault Fault Fault Fault Fault Fault Fault Fault Harvey Ridge Harvey Ridge Harvey Ridge Harvey Ridge a a a a a a a a a a a a i i i i i i i i i i i i l l l l l l l l l l l l e e e e e e e e e e e e m m m m m m m m m m m m overlying the r r r r r r r r r r r r a a a a a a a a a a a a P P P P P P P P P P P P Cockburn 1 Cockburn 1 Cockburn 1 Cockburn 1 Cockburn 1 Cockburn 1 Harvey Transfer Harvey Transfer Harvey Transfer Harvey Transfer Harvey Transfer Harvey Transfer Harvey Transfer Harvey Transfer Harvey Transfer Harvey Transfer Harvey Transfer Harvey Transfer Rockingham 1 Rockingham 1 Rockingham 1 Rockingham 1 Rockingham 1 Rockingham 1 Badaminna Badaminna Badaminna Badaminna Badaminna Badaminna Badaminna Badaminna Badaminna Badaminna Badaminna Badaminna injection zone South Perth Shale South Perth Shale South Perth Shale South Perth Shale h h h h a a a a e l l e l e e l Leederville Leederville Leederville Leederville Leederville Leederville Leederville Leederville Leederville Leederville Leederville Leederville t t t t hP hP hP hP e e e e r r r r t t t t h h h h S S S S S S S S o o o o u u u u Yarragadee Yarragadee Yarragadee Yarragadee Yarragadee Yarragadee Yarragadee Yarragadee Yarragadee Yarragadee Yarragadee Yarragadee Cattamarra Cattamarra Cattamarra Cattamarra Cattamarra Cattamarra Cattamarra Cattamarra Cattamarra Cattamarra Cattamarra Cattamarra Pinjarra 1 Pinjarra 1 Pinjarra 1 Pinjarra 1 Pinjarra 1 Pinjarra 1 Yarragadee Yarragadee Yarragadee Yarragadee Yarragadee Yarragadee Yarragadee Yarragadee Yarragadee Yarragadee Yarragadee Yarragadee Coal Measures Coal Measures Coal Measures Coal Measures Coal Measures Coal Measures Coal Measures Coal Measures Coal Measures Coal Measures Coal Measures Coal Measures YILGARN YILGARN YILGARN YILGARN YILGARN YILGARN YILGARN YILGARN YILGARN YILGARN YILGARN YILGARN Harvey Ridge Harvey Ridge Harvey Ridge Harvey Ridge Harvey Ridge Harvey Ridge Harvey Ridge Harvey Ridge Harvey Ridge Harvey Ridge Harvey Ridge Harvey Ridge CRATON CRATON CRATON CRATON CRATON CRATON CRATON CRATON CRATON CRATON CRATON CRATON Cattamarra Cattamarra Cattamarra Cattamarra Cattamarra Cattamarra Cattamarra Cattamarra Cattamarra Cattamarra Cattamarra Cattamarra Coal Measures Coal Measures Coal Measures Coal Measures Coal Measures Coal Measures Coal Measures Coal Measures Coal Measures Coal Measures Coal Measures Coal Measures Eneabba Eneabba Eneabba Eneabba Eneabba Eneabba Eneabba Eneabba Eneabba Eneabba Eneabba Eneabba VLAMING VLAMING VLAMING VLAMING VLAMING VLAMING VLAMING VLAMING VLAMING VLAMING VLAMING VLAMING Lake Preston 1 Lake Preston 1 Lake Preston 1 Lake Preston 1 Lake Preston 1 Lake Preston 1 SUB-BASIN SUB-BASIN SUB-BASIN SUB-BASIN SUB-BASIN SUB-BASIN SUB-BASIN SUB-BASIN SUB-BASIN SUB-BASIN SUB-BASIN SUB-BASIN O O O O O O O O O O O O U U U U U U U U U U U U G G G G G G G G G G G G H H H H H H H H H H H H Lesueur Lesueur Lesueur Lesueur Lesueur Lesueur Lesueur Lesueur Lesueur Lesueur Lesueur Lesueur Cockleshell Gully Fm Cockleshell Gully Fm Cockleshell Gully Fm Cockleshell Gully Fm Sandstone Sandstone Sandstone Sandstone Sandstone Sandstone Sandstone Sandstone Sandstone Sandstone Sandstone Sandstone FAULT FAULT FAULT FAULT FAULT FAULT FAULT FAULT FAULT FAULT FAULT FAULT 8 Wonnerup 1 Wonnerup 1 Wonnerup 1 Wonnerup 1 Wonnerup 1 Wonnerup 1 BUNBURY BUNBURY BUNBURY BUNBURY BUNBURY BUNBURY BUNBURY BUNBURY BUNBURY BUNBURY BUNBURY BUNBURY TROUGH TROUGH TROUGH TROUGH TROUGH TROUGH TROUGH TROUGH TROUGH TROUGH TROUGH TROUGH
