Development of heavy oil deposits increases each year, due to consumption of conventional oil reserves. However, extraction process of heavy oil faces a number of problems. The main of these problems are high density and viscosity of heavy oil as well as high content of asphaltene-resin-paraffin components, which can be precipitated. Currently, the main methods that are being used for heavy oil recovery are thermal methods, like steam assisted gravity drainage (SAGD), cyclic steam stimulation (CSS) and in-situ com...

In this work the quality of the slim-tube packing was demonstrated, the inner diameter and porosity was determined by using X-ray computed tomography. The literature analysis of slim tube packing over was carried out. It is noted that in all cases of slim tube does not accept the most theoretically possible dense rhombic packaging. Moreover, the presence of interstices due to loose contact of the grains to each other illustrates the technological limitations when filling out. To confirm the absence of signs of def...
