Ms. Anastasia Pirogova

Ms. Anastasia Pirogova

PhD Student. Research topic: Estimation of attenuation from borehole seismic data using constrained full-waveform inversion

Anastasia has designed an attenuation estimation algorithm from VSP data using waveform inversion constrained by high resolution 1D velocity and density model obtained from well log data. The high-resolution velocity model allows explicit modelling of short-period multiples and scattering, and hence allows separation of intrinsic and scattering attenuation. Anastasia has applied this algorithm to a number of VSP datasets both onshore and offshore Australia.

Anastasia has a BSc and MSc in geophysics from Lomonosov Moscow State University.

Mr. Yongyang Sun

Mr. Yongyang Sun

PhD Student. Research topic: Effects of Solid Pore Infill on Elastic Properties of Rocks and its Application to Heavy Oil Field Exploration

Yongyang (Jerry) Sun is a current PhD student in Exploration Geophysics at the Centre for Exploration Geophysics at Curtin University. In 2010 Jerry received a BSc in Prospecting techniques and Engineering at China University of Petroleum, Beijing and in 2015 he received a MSc in Geological Resources and Geological Engineering from China University of Petroleum, Beijing. Jerry is a recipient of the Curtin International Postgraduate Research Scholarship (CIPRS).

His research interests are in rock physics, well-logging analysis and seismic inversion. His current research includes development of advanced rock physics models for solid substitution in porous rocks, and for stress dependency of elastic properties of fluid- and solid-saturated rocks and his thesis project is titled “Modeling the effect of liquid and solid infill on elastic moduli, dispersion, and attenuation in porous media”.

One aspect of his project involves studying the moduli dispersion and attenuation in fluid-saturated rocks at a full frequency range (Gassmann low-frequency limit to ultrasonic high-frequency limit). This frequency dependency is termed as “squirt-flow” effects and caused by the pressure gradients between compliant pores (soft pores with aspect ratio < 0.01) and stiffer pores (with aspect ratio > 0.1). Another aspect involves studying the effect of the high viscous materials or real solids on the moduli dispersion.

To date, Jerry has published six peer-reviewed journal papers in the leading geophysical journals (Two are published in Journal of Geophysical Research-Solid Earth). He also serves as the guest reviewer of Geophysical Prospecting, Geophysics, and International Journal of Rock Mechanics and Mining Sciences.

Mr. Alexander Costall

Mr. Alexander Costall

PhD Student. Research topic: Electromagnetic characterisation of regional-scale aquifers, Perth, Western Australia

Alex is a PhD student at the Department of Exploration Geophysics, Curtin University. He was awarded a research training program scholarship from Curtin University and the Australian Government, and has received multiple awards from ASEG and AIG. He completed a Bachelor of Science (Geophysics) with first-class honours in 2014, and has been actively involved in teaching and research activities within the department.

Alex has worked in the field collecting various geophysical data all around Australia, with a particular focus on electromagnetic, electrical, and seismic techniques. Alex’s thesis is titled “Hydro-geophysics in High-Quality Coastal Aquifers” and focuses on data acquisition and numerical modelling of solute transport and electrical geophysics in the near-shore coastal environment. In particular, electrical resistivity imaging (ERI) and groundwater solute transport modelling techniques are developed for recovery of the hydrogeological architecture of coastal margins.

ERI acquisition and processing parameters along with the influence of hydraulic anisotropy and heterogeneity in karstic aquifers are explored with examples selected along more than 100 km of coastline proximal to Perth, Western Australia. The methods will contribute to accurate predictive groundwater modelling and sustainable management of high quality coastal aquifers worldwide.

Ms. Snežana Petrovic

Ms. Snezana Petrovic

PhD Student. Research topic: Elemental analysis via prompt gamma neutron activation for diamond drilling

I completed my Bachelor and Master degrees in Applied Geophysics at the University of Belgrade in Serbia. While pursuing my masters, I also started one-year internship in Agile Seismic, a privately-owned, geophysical company where I was working as a seismic processing geophysicist. I continued to work there for two years once my internship was completed.

Currently I am pursuing a PhD at the Discipline of Exploration Geophysics at Curtin University. The research project I am working on aims to design, develop and test a prototype of a nuclear (prompt gamma neutron activation) logging-while-drilling tool for slim-holes in mineral exploration. Such a tool could measure the elemental matrix composition in near real-time, and with timely, reliable data we can alter exploration drilling decisions; thus, transforming mineral exploration where information about elemental composition usually arrives weeks afterwards.

Providing timely and reliable data, this innovative tool I am working on will change existing, drilling strategy, providing considerable savings to mineral exploration industry. This technology would drastically reduce time and cost of many exploration and development programs in most base metals mines and provide information that would improve almost every stage of mining and mineral process. The potential of this project is recognised by Boart Longyear Ltd, the largest drilling operator and manufacturer of drilling equipment for mining and drilling companies worldwide, who funded this project.
