Simulation of the effect of hydrate adhesion properties on flow safety in solid fluidization exploitation

Petroleum, 2023
During the solid fluidization exploitation of marine natural gas hydrates, the hydrate particles and cuttings produced via excavation and crushing are transported by the drilling mud. The potential flow safety issues arising during the transport process,

Assessing the Influence of Confining Pressure on the Consolidation of Granular Bulk Models Using an Integrated Sensor System

Sensors
Large-scale bulk models offer a promising approach for the experimental investigation of flow in porous media. However, conventional configurations frequently lack adequate confinement systems, resulting in model instability under dynamic flow conditions.

Study on the Optimal Production Pressure of Different Types of Natural Gas Hydrate Based on Formation Stability

Geofluids, 2020
Natural gas hydrate is an ice-like crystal formed by methane and water, which is a new type of strategic energy with huge reserves. The exploitation of deep-sea hydrate will cause a large amount of decomposition of hydrate, which will decrease the ...

An experimental study of proppant transport mechanisms to the pump intake in low-flow oil wells

Petroleum Research
The exploitation of low-flow oil wells following hydraulic fracturing is often hindered by residual proppant and proppant production during early production phases, which can infiltrate pumps and drastically shorten their service life.

High-pressure gas hydrates [PDF]

Phys. Chem. Chem. Phys., 2008
It has long been known that crystalline hydrates are formed by many simple gases that do not interact strongly with water, and in most cases the gas molecules or atoms occupy 'cages' formed by a framework of water molecules. The majority of these gas hydrates adopt one of two cubic cage structures and are called clathrate hydrates.
