PhD Project:

Site Specific Geologic Model Construction for CO2 Sequestration

Commenced: 2001

Supervisor: Assoc Prof Simon C. Lang

Project support: : APCRC - GEODISC Program

Scholarship support: The University of Adelaide and GEODISC

Project 2 of the APCRC's GEODISC program involves site specific evaluations for CO2 sequestration. The aim of the project is to construct a three-dimensional geologic model that can be used to simulate the subsurface injection and storage of CO2. The construction of a geologic model involves the integration of core descriptions, wireline suites, seismic reflection data, mercury injection capillary pressure data, palynology and pressure data. Of particular interest for CO2 injection is the geometry, size and fluid flow properties properties of potential reservoirs as well as the capacity and extent of sealing units.

The geomechanics, hydrodynamics, chemistry, economics and risking of CO2 sequestration is being investigated by other researchers concurrently with the construction of a geologic model.

Robert Root graduated from Queensland University of Technology with a Bachelor of Applied Science in 1999. His Masters Degree was completed in 2001 and involved reservoir characterisation and sequence stratigraphy of the interior cratonic to marginal marine strata of the Eromanga Basin (see figure 1). Robert commenced a PhD project on site specific evaluations for CO2 sequestration at the National Centre for Petroleum Geology and Geophysics in 2001. Current research interests include sedimentological reservoir characterisation and the application of neural networks and geostatistical methods to petroleum exploration and development. Robert is a member of PESA and AAPG.
