Exploitation of natural gas hydrate is expecting to be an important strategic way to solve the problem of energy depletion. Understanding the effectiveness of the well configuration plays a pivotal role in gas production from the hydrate reservoir. This study evaluates the methane hydrate...

The cubic hydrate simulator (CHS) is used to study the methane hydrate production behaviors in porous media by the thermal stimulation with a five-spot well system. The hot water injection rates range from 10.0 to 40.0ml/min. The thermal stimulation process is analyzed, and the conclusions are...

The gas production behavior from methane hydrate in the sediment by depressurization was investigated in a novel pilot-scale hydrate simulator (PHS), a three-dimensional pressure vessel of 117.8L. Experimental results are compared with those in a cubic hydrate simulator (CHS) with the effective...

This study reports the deactivation mechanisms of the solid acid catalyst Amberlyst 70 during the esterification of bio-oils from mallee biomass and the methods for catalyst regeneration. The metal ions in bio-oil deactivated Amberlyst 70 via ion exchange with the hydrogen ions on/in catalyst,...

The Cubic Hydrate Simulator (CHS), a three-dimensional 5.8L cubic pressure vessel, and the Pilot-Scale Hydrate Simulator (PHS), a three-dimensional 117.8L pressure vessel, are used for investigating the production processes of hydrate. The gas production behaviors of methane hydrate in the...

The kinetic behaviors of methane hydrate dissociation under depressurization in porous media are investigated through experimental and numerical simulations. Hydrate samples with low gas saturations (SG⩽0.10) are synthesized in the pilot-scale hydrate simulator (PHS), a novel three-dimensional...

The cubic hydrate simulator (CHS) is used to study the methane hydrate production behaviors in porous media with three different methods, which are the depressurization (DP) using a single well, the heat stimulation using five-spot well (HS-5S), and the heat stimulation in conjunction with...

In this work, the decomposition behaviors of methane hydrate in the porous media are investigated in the three-dimensional cubic hydrate simulator (CHS) using the huff and puff method with a single well with the different injection temperatures and different injection time. The changes of the...
