Professor Boris Gurevich made a Society of Exploration Geophysicists (SEG) Honorary Lecturer to South and East Asia for 2019

Professor Boris Gurevich from Curtin’s WA School of Mines: Minerals, Energy and Chemical Engineering has been made a Society of Exploration Geophysicists (SEG) Honorary Lecturer to South and East Asia for 2019.

In being appointed to the position, Boris was described as an outstanding communicator of ideas and recognised for the quality of his contributions to geophysics. Our congratulations to Boris on this special honour.

Welcome to new PhD student Mr. Jiabin Liang

New PhD student Arrival: Mr. Jiabin Liang.

Jiabin received his Bachelors degree from the China University of Geosciences (Beijing) in 2010. After graduating, he joined the China National Petroleum Corporation to work as a seismic acquisition geophysicist in a seismic crew in Saudi Arabia for 5 years. In 2015, Jiabin then undertook a Master’s at the China University of Petroleum, Beijing.

Jiabin’s Supervisor will be Prof. Boris Gurevich and his research topic will be on “Elastic properties modelling and digital rock physics”.

Seminar: Data-Driven Modeling to assess hazard due to CO2 leakage

Dr. Jina Jeong, Assistant Professor, Kyungpook National Univerisity

Title: Data-Driven Modeling to assess hazard due to CO2 leakage

Held: Thursday 12 July 2018, 3PM–4PM

ABSTRACT:

One of the important tasks of CCS is ensuring the stability of CO2 storage through all periods. In this presentation, a few data-driven modelling techniques that can be applied to ensure safety of CO2 storage site will be introduced.

The following methods are proposed as potential tools for effective assessment of risk of CO2 leakage:

  1. A method to predict lithofacies from multiple well-logging data based on sequence labelling algorithm: To interpret lithofacies sequence of borehole from well-logging data, we modified the conventional sequence labelling algorithm to incorporate a bi-directional characteristic of geological stratum. Applying the proposed method, non-cored or partially cored boreholes can be characterised based on well-logging data and, therefore the prediction accuracy of the subsurface heterogeneity can be improved, which is important to understand the leakage pathway of CO2.
  2. An ensemble regression method to analyse the CO2 monitoring data: Based on the actual CO2 leakage monitoring data acquired from the artificial CO2 release test facility in South Korea (EIT site), it is confirmed that the method can predict a possibility and amount of CO2 leakage before critical leakage is observed. We believe that the proposed method is not confined to estimations of CO2 concentration and may be applied to various real-time monitoring data from subsurface sites to develop automated control and management or decision-making system.

Visiting Researcher Dr. Jina Jeong arrives at Curtin

Visitor Arrival: Visiting Researcher Dr. Jina Jeong.

Jina is a Senior Researcher from the Korea Institute of Geoscience and Mineral Resources, South Korea, and holds a PhD in Hydrogeology/Geostatistics/Geoinformatics.

Her recent research interests include Surface and Subsurface Characterisations, Geological informatics, Groundwater flow and contaminant transport in subsurface and Geo-ICT convergence technologies.

She will be with us for 2 months, working alongside Prof. Maxim Lebedev on a project titled: “Identification of electro-facies from well logs in presence of compaction using a data assimilation method”.
