Dr Gregory Smith
Greg has over 35 years of experience in petroleum geology, geophysics and geochemistry involving research, technical and managerial positions at Exxon, ARCO, BHP, Woodside/Shell and in the Herman Research Laboratory. Initially this was focused on research into 3D modelling of basins, sediments and organic geochemistry, followed by a successful period in petroleum exploration including several major discoveries, and moving onto field development and production for many large projects.Back to top
Greg's overall research interests involve geological interpretation and geostatistical analysis of large seismic, well log, core and production datasets to build 3D computer structural and property models of sedimentary basins or petroleum fields (eg with Petrel), including scenario modelling of the most probable geology and resource/reserve estimates.
Specific interests include low T-P burial and thermal history modelling of basins, organic matter petrology and geochemistry, and property modelling of the associated sediments and their diagenesis. This work is being pursued in collaboration with Curtin Statistics and Engineering departments, the WA Organic & Isotope Geochemistry group, and will use equipment in the John de Laeter centre such as the TOF-SIMS.Back to top

Focused on Honours, Masters and PhD supervision and training in specialised topics such as Seismic and Sedimentary Facies analysis, Hi-Res Sequence Stratigraphy and 3D Reservoir Modelling, including field based studies in the Flinders (Deep Marine-Shelf and Salt Tectonics), Sydney (fluvio-deltaic), Perth/Carnarvon and Otway and Gippsland Basins.
Expertise in seismic mapping and geological modelling in Petrel at the regional, prospect and field scales for exploration, development and production, including volumetrics and reserves estimation under uncertainty.Thesis topics supervised on the NWS, Southern Margin, Perth, Gippsland and Canning Basins.
Expertise in organic petrology, geochemistry and maturation modelling.Back to top
Petroleum source rock geochemistry, the paragenesis of organic rich sediments and the evolution of the carbon and sediment cycles with earth history.
The use of Geostatistical techniques, especially for correlation of seismic attribute volumes with 3D geological and reservoir simulation models, and the use of outcrop analogues to build 3D geological models.
Current research projects include:
- Basinwide 3D thermal modelling of organic matter maturation data in Petrel
- Analysis and correlation of organic matter composition and texture in sediments between Optical, SEM and GC-MS
- Experimental Designs to minimize the number of model scenarios for reserves estimates
- Multi-dimensional Kriging of stochastic log inversion data with 4D seismic data to constrain 3D time step reservior simulation models
- Use of mapped outcrop data to guide 3D geological modelling in Petrel (currently in Salt tectonic and deep marine basins).
