Removal and Prevention of Asphalts, Resins and Paraffins Deposits (ARPD) in wells and pipelines

A little more information about the companies technology: Removal and Prevention of Asphalts, Resins and Paraffins Deposits (ARPD) in wells and pipelines.

Technologies of such type are based on the use of chemical reagents, solvents, inhibitors and ARPD dispersants, which possess high dispersant and detergent properties. Specific of the technology of using dispersants consists in reducing the activation energy of the components of the chemical reagent by mixing with hot water. The composition is metered by one- or one and a half- volume of a well or a pipeline.

The technology of solvents ARPD removal is based on the use of multicomponent hydrocarbon systems with additives of surfactants, having effect on deposits and increasing their transformation to the solvent repeatedly. Depending on the treatment purpose (pump cleaning, wellbore deposit removing or pipeline treatment) 200 to 2,000 liters of solvent can be used during processing.

Prevention of Asphalts, Resins and Paraffins Deposits is carried out by entering detergent inhibitors of paraffin deposits (as well as paraffin crystal modifiers) into the flow of produced or transported liquid (oil or emulsion). The reagent is applied by the constant entering with the use of metering equipment or periodically by means of one-time mechanized treatments, including the bottomhole formation zone treatment.

High efficiency of technologies is confirmed by using at many deposits in central Russia and Western Siberia.
