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...

The Pilot-Scale Hydrate Simulator (PHS, 117.8L pressure vessel) is used to study the methane hydrate dissociation with dual horizontal wells using both the steam assisted gravity drainage (SAGD) and the steam assisted anti-gravity drainage (SAAD) methods. This study is the first time to propose...

A 117.8L three-dimensional pressure vessel is used to study the methane hydrate dissociation with the steam assisted gravity drainage (SAGD) method. It is called the Pilot-Scale Hydrate Simulator (PHS). This study proposes the evaluation and the comparisons of the gas production performance by...

To have an overall investigation of cold storage characteristics to help to promote the application, a novel small scale of gas hydrate cold storage apparatus was designed. The amount of cold energy, growth rate, Hydrate Packed Factor (HPF) and overall heat transfer coefficient during the cold...

In iron and steel industry, byproduct gases are important energy. Therefore it is significant to optimize byproduct gas distribution to achieve total cost reduction. In this paper, a dynamic mixed integer linear programming (MILP) model for multi-period optimization of byproduct gases is used to...
