Method for estimating mass content of paraffins in Achimov condensates based on chromatographic data

Abstract

The paraffin content in production well streams must be monitored to assess the risks of wax formation during the production, transportation, and treatment of hydrocarbons. This is especially important when operating Achimov reservoirs containing fluids with a high content of heavy paraffin-type hydrocarbons. The standard approach for determining the paraffin content in oil using certified methods involves a long process of sample preparation and separation in selective columns followed by freezing out of paraffin from toluene extract. An urgent task is to find methods for the rapid assessment of paraffin content in condensates. The article considers a method for estimating the mass content of paraffins in condensates based on chromatographic data on the component-fractional and component-group composition of degassed condensate. The authors provide a comparison of the mass fraction of paraffins obtained by the proposed method and measured by the standard certified method.
