Studying Hydrocarbon Resource Production Techniques that Alleviate Global Warming

ABSTRACT:
The Laboratory of Resource Production & Safety Engineering is dedicated to excellence in engineering applications for the production of mineral/hydrocarbon resources in an efficient, safe and environmentally responsible manner. Geological CO2 storage and related techniques are also studied in the quest to reduce the CO2 emitted by the production and utilization of these resources.

DETAILED:
Geological CO2 sequestration is studied not only for the purpose of reducing CO2 emissions, but also to enhance hydrocarbon resource production. For example, enhanced coal bed methane recovery (ECBMR) achieved by injecting CO2 into deep coal seams is expected because coal bed methane can be replaced with CO2, whose adsorption on coal is twice that of CH4. Enhancement of oil recovery (EOR) is also expected to be achieved by injecting CO2 into oil reservoirs, because oil swelling and oil viscosity reduction are caused by CO2 dissolution. Moreover, microbial restoration of natural gas deposits caused by stimulating the microbial conversion reaction of CO2 into CH4 in the subsurface is also being studied.

Meanwhile, safety and environmental assessments during and after CO2 injections are needed to advance geological CO2 storage.
Safety guidelines need to be established, and long-term environmental changes require evaluation.
With this perspective, we conduct natural-analogue studies of CO2 dispersion and diffusion characteristics in shallow sediment.
These characteristics can be measured by obtaining gas concentration measurements on the surface.
This data is very useful when constructing a numerical model for effective CO2 diffusion from deep sediment to the surface.
