The formation of natural gas hydrates in oil and gas pipelines is an important concern due to the risk of hydrate blockage. In order to reduce the expenses with the use of chemicals to avoid hydrate plugging, more studies about the slurry flow and…
In this study, the thermodynamic and structural characteristics of natural gas hydrates (NGHs) retrieved from gas hydrate mounds (ARAON Mound 03 (AM03) and ARAON Mound 06 (AM06)) in the Chukchi Sea in the Arctic region were investigated. The gas…
Since the success of recovering natural gas from hydrate-bearing reservoirs (HBRs) in Shenhu Area of the northern South China Sea in 2017, China has successfully produced natural gas from hydrates in permafrost and ocean environments. It certainly…
The time-frequency (TF) analysis method plays a significant role in the detection of natural gas hydrates. As a data-driven method, compressed sensing (CS) has been widely used in the TF methods due to the sparsity of the TF representation. This…
As one of the most potential unconventional fossil fuels, the safe and efficient production of natural gas hydrates (NGHs) has become a prominent research area worldwide. Water flow erosion, which has been proven to be a powerful methane hydrate…
Nanobubbles have attracted wide scientific attention due to their large number of potential applications in nanotechnology, and they are ubiquitous during natural gas hydrates (NGHs) mining which is one of the strategic energy resources. Molecular…
In this study, three kinds of driving forces for the dissociation of CH4 hydrates were experimentally investigated to determine which was optimal for a consistent control of the depressurization process. A specially designed one-dimensional (1-D)…
Before performing commercial scale production of natural gas hydrates (NGHs), it is inevitable to estimate the productivity, production period, optimal operation parameters, and further evaluate the technical and economic feasibilities of NGHs field…
The formation of natural gas hydrates in oil and gas pipelines is an important concern due to the risk of hydrate blockage. In order to reduce the expenses with the use of chemicals to avoid hydrate plugging, more studies about the slurry flow and…
Natural Gas Hydrates (NGH) collected during the Ghass cruise 2015 in the Western Black Sea onboard the R/V Pourquoi pas? are characterized by a suite of techniques. Gas Chromatography and Raman spectroscopy are used for the identification of the…

For experiments simulating marine sediments that include massive hydrate crystals for geotechnical stability assessment and for development of hydrate recovery techniques for such natural gas hydrate deposits, mechanical properties of massive natural…
With oil and gas exploitation developing towards deep-water fields, the extreme, low-temperature, and high-pressure environments are ideal for hydrate formation in subsea pipelines. Hydrate formation, growth, aggregation, and deposition in the…
A transient simulation tool for the gas hydrate slurry flow is crucial for hydrate flow assurance in the petroleum industry. In this work, we propose a new transient model for gas hydrate slurry flow in oil-dominated flowlines. A two-fluid model and…
