Abstract
The effect of oil-displacement system NINKA on the composition and physical and chemical properties of high-paraffin crude oil was investigated. Prior to testing, the crude oil samples were heated to 200 °C in the presence of NINKA system. It was found that the molecular-mass distribution of normal hydrocarbons, the sulfur content and density of crude oil had been unaffected by the thermal treatment in the presence of NINKA system; however, the contents of resins and asphaltenes, organic acids and nitrogen had changed significantly.
