... hydrocarbons associated with them is very complicated; within the cross sectionof the deposit, 3 production targets have been identified: I - bottom target, II - middle target and III - top target.The paper highlights the differences in the composition and properties of the oil samples belonging to different deposit targets. This information can of use helping to clarify geological structure, to determine the characteristics of the crude hydrocarbons and productivity of each oil target when they are operated ...

... energy feedstock. This is, above all, a raw material for a number of valuable chemicals of various purposes. Selection of respective refining process of highly viscous oils is an urgent task that requires complete information about their physico-chemical properties, composition and quality of petrochemicals produced from them. Therefore, a comprehensive study of the properties and component, hydrocarbon and fractional composition of oil is a major priority Materials and methods Materials — oil samples ...

... evaluated. The features of the element composition, component, structural-group and hydrocarbon composition of bitumen changes depending on their chemical types and modes of microwave exposure are found out. New data on the change in the structure and properties of asphaltenes under microwave exposure and the composition of the liquid products of their destruction is gained. Materials and methods 1. Experiments on microwave treatment of bituminous sands held in the microwave oven Elenberg MS-1400 ...
