Abstract
As production moves to remote/deepwater locations, the risk and severity of hydrate formation in
subsea flowlines increase substantially making the conventional full-MEG injection strategy
economically unviable, thereby requiring a paradigm shift in the hydrate management approaches.
Anti-agglomerants (AAs) and under-inhibited MEG systems can be considered vital to the safe and
economic production of oil and gas reservoirs under such conditions. Current industry AAs are
effective in nature, however, their eco-toxicity profile may limit their usage in environmentally
sensitive countries like Australia. This thesis presents novel work on the use of biocompatible AAs
and regenerated industrial MEG under under-inhibited conditions.
