Naturally occurring gas (mostly methane) hydrates along the continental margins (coastal offshore) and permafrost sediments are the clean source of energy outnumbering the rest forms of conventional energy sources. Recent successful methane recoveries from hydrates in Eastern Nankai Trough through depressurization (offshore central coast of Japan, 2014 and 2017), Shenhu area of China (for more than 7 days) and CO2+N2 and CH4 exchange (North Slope of Alaska, 2012) have renewed interest in investigating the feasible technology development at field scale.
Methods of depressurization, thermal heating, inhibitor application and combined have been successfully practiced in laboratory and field successes to some extent. Methane recovery from hydrates is challenging due to the trapped gas in water cages in the pores of sediments.
This project aims to investigate an efficient ways of producing methane from the natural gas hydrate reservoirs in porous media, and the simultaneous sequestration & storage of the anthropogenic CO2 through gas-gas replacement (CH4-CO2, CH4-CO2+N2) in hydrates inside the pores of sediments, respective kinetics and the applied recovery methodologies, alone or in combination with the depressurization, chemical inhibitor injection and thermal methods. These will be achieved through experimental investigations and/or numerical simulations using the commercial simulators, codes, even the development of simulation codes. This project further aims to explore the options of the subsurface oceanic and geological storage options in oceanic and arctic environments.
Candidates should have (or expect to achieve) a UK honours degree at 2.1 or above (or equivalent) in Petroleum, chemical, oil and gas, energy engineering or equivalent. Chemical Engineering with knowledge of geology/geosciences/reservoir engineering.
Knowledge of: Practical petroleum and chemical engineering concepts covering geosciences, thermodynamic and kinetic behaviour of gases in porous media and reservoir engineering & simulation fundamentals. Knowledge/ and experience of reservoir simulation and the respective simulation tools with the programming languages, and code development will be advantageous.
