In situ combustion (ISC) plays a significant role in the exploitation of heavy crude oil. In this study, the thermal behaviors and kinetics of combustion of heavy crude oil and its saturates-aromatics-reins-asphaltenes (SARA) fractions were…
Simulation of the seismic wave propagation in natural gas hydrate (NGH) is of great importance. To finely portray the propagation of seismic wave in NGH, attenuation properties of the earths medium which causes reduced amplitude and dispersion need…
Thermal methods have attracted a significant attention for the extraction of high-viscosity oil and natural bitumen. One of the promising methods for enhanced oil recovery (EOR) is in-situ combustion (ISC). In the reservoir, the combustion process…
As a new unconventional clean energy, natural gas hydrate has attracted attention in recent years. In marine natural gas hydrate reservoir drilling, hydrate cuttings will return upward in annulus. In this process, hydrate cuttings will decompose…
In order to study the decomposition process of gas hydrate depressurization production, a mathematical model of gas hydrate reservoir is established in cylindrical coordinate system and it is solved by finite difference method. With this modeling…
Hydrate generation and pipe blockage in long-distance natural gas transmission pipelines has always been a major issue affecting the transmission safety. Although considerable progress have been made in recent years, there is still a long way to go…
The formation of hydrate will lead to serious flow assurance problems in deepwater submarine natural gas transmission pipelines. However, the accurate evaluation model of the hydrate blocking risk for submarine natural gas transportation is still…
