Analysis of oils taken from wells No. 2153 and 2364 of Neft Daslari OGED with an agent containing aromatic solvents and modifying additives

The article discusses the reasons for the occurrence of asphaltene-resin-paraffin deposits in production tubings and pipelines, the ways to eliminate the issues, and a novel reagent based on the aromatic solvents and modifiers (copolymer of polyethylene polyamine, ethylene oxide and propylene oxide based on glycerin) developed to solve the issue. The efficacy of the newly developed XL-6 reagent against asphaltene-resin-asphaltene deposits was determined, and the effect on non-Newtonian oil rheology was investigated. The efficiency of the developed new XL-6 reagent against asphaltene-resin-paraffin deposits was studied in a comparative manner with the СНПХ-2005 reagent in the consumption interval of 50–450 g/t on the oils taken from the wells No. 2153 and 2364 of Neft Dashlari OGED (Oil-Gas Extraction Department). It has been established that XL-6 reagent at consumption of 300–350 g/t shows high efficiency against ARPD. The effectiveness of XL-6 reagent on the rheology of the studied oil at a flow rate of 300 g/t was studied. The studies were also carried out in comparison with the СНПХ -2005 reagent and crude oil.
