In this work the likelihood of asphaltene deposition problems during dynamic displacement of oil by natural gas in unconsolidated porous media is experimentally inspected. The two different rock materials, limestone and sandstone, are used as a representative of porous media. Dynamic flow experiments indicate that the increase of natural gas injection inc...

fundamental understanding of the goaf gas distribution in a gassy coal mine is necessary for developing effective goaf gas drainage strategies in the longwall coal mine. the goaf gas was subjected to the surface and body forces that were classified depending upon whether they acted on the surface area or the volume of the gas element. of these forces, the body forces were more predominant in di...

Estimating oil and gas production from assets is essential to carry recovery processes. From the many techniques tools used for such a task, compositional simulation model important miscible displacement problems with complex phase behavior. In this model, fluid flow in porous media described by set of conservation equations. The solution these involves spatial time discretization schemes appro...

Laminar miscible displacement flows in narrow, vertical, eccentric annuli show a wide range of interesting physical phenomena, e.g. static layers and channels, dispersive spikes/fronts various instabilities. These are relevance to the primary cementing wells, where gas leakage greenhouse emissions can result from ineffective cementing. The current popular way model this process is via Hele-Shaw...
