Overview

The Mathematical Imaging and Geophysics Group (MIG) is primarily focused on developing advanced mathematical tools to better image the interior of the Earth at a variety of scales, namely, from the global map of the crust and mantle to the detailed subsurface structure of a hydrocarbon/geothermal reservoir. Through developing novel mathematical modelling tools and the state-of-the-art seismic imaging technology, analysing the full waveform contents of high-quality seismic data, and relying on high performance computing, we aim to gain insight into the geodynamic processes of the Earth's interior and provide advanced methods to solve realistic problems faced by modern oil-and-gas exploration/production companies and contractors.

Research Interests

Earthquake Seismology

Earthquake seismology is one of the most powerful tools to study the interior of the earth. When an earthquake or explosion occurs, part of the energy is released as elastic waves that transmit through the earth in all directions. The waves are then detected and recorded by seismograms, which measure and record the motion of the ground. The information is then used to determine earthquake locations, the subsurface structures and so on.

Mathematical Modelling and Inversion

Mathematical inverse problems are some of the most important problems in science and engineering. An inverse problem is the process of investigating from a set of indirect measurements the causal factors that produced them. Such situations are common in many application areas such as underground prospecting, medical imaging, non-destructive testing, computer vision, machine learning, data mining, and other fields. We develop new mathematical technology to solve inverse problems in earth sciences.

Exploration Geophysics

Exploration geophysics is an applied branch of geophysics. It aims to explore the first few kilometres of the earth’s crust by identifying rock and/or fuild types and structures. The ability to do this is very invaluable in the exploration for oil and gas and in the mining and construction industries. Full waveform inversion is a recent hot topic in seismic exploration. The Mathematical Imaging and Geophysics Group has special interests in conducting full waveform modelling and imaging studies of hydraulic fracturing for unconventional oil and gas exploration.
