Geological evaluation of the Eocene Latrobe Group in the offshore Gippsland Basin for CO₂ geosequestration.

Title page, table of contents and abstract only. The complete thesis in print form is available from the University of Adelaide Library. / This study area for this research is characterised by a regional anticline plunging to the east-south-east with large-scale internal architecture comprising transgressive, retrogradationally stacked stratigraphy that dips gently landward and is unconformably truncated by overlying sealing units. The primary reservoir/aquifer targets for CO₂ injection are palaeo-shoreline parallel nearshore sandstone bodies characterised by high porosity and permeability and good interconnectivity. The key regional sealing unit is the Lakes Entrance Formation, which consists of mudstone and marl capable of sealing large columns of CO₂. The proposed stategy for CO₂ geosequestration is to inject CO₂ outside four-way structural closure to allow up-dip fluid migration to the north then west governed by the structure of regional sealing units. Probabilistic estimates of CO₂ capacity utilising the proposed strategy indicate that 1395-2575 Mtonnes could be sequestered. / http://proxy.library.adelaide.edu.au/login?url= http://library.adelaide.edu.au/cgi-bin/Pwebrecon.cgi?BBID=1281480 / Thesis (Ph.D.) -- University of Adelaide, Australian School of Petroleum, 2007
