...ABSTRACT ABSTRACT Unconventional hydrocarbon reservoirs are deposits that do not produce economically without the assistance of massive stimulation or the application of special recovery technologies. Hydraulic fracturing is a stimulation technique that aims to increase the well productivity...

... applied on the power storage, desalination, CO 2 capture and etc. (Xu et al, 2011; Liu et al,2013; Chen et al, 2015). However, natural gas hydrate is a double-edged sword in the engineering. It has been found that the phase transition of hydrate can block the pipes and damage the reservoir structure...

... ABSTRACT In-situ dissociation process of gas hydrate by partial-oxidation and heating through acid or oxidant injection into the reservoir has been proposed. However, it was only evaluated by simulator based on the calorific value of acid. In this study, we carried out gas hydrate dissociation...

... ABSTRACT In this study solute transport experiments using a dye in a twodimensional water tank with the dimensions of 100 cm height, 100 cm length and 3 cm thickness were conducted to investigate solute transport behaviors in a subsurface reservoir with underground dam. A synthetic flow field...
