The formation of organic deposits is one of the most serious complications when producing oil. These complications are often eliminated by applying the methods that prevent the organic deposits formation, the determination of the reliable effectiveness of which is an important task. The field diagnostics of organic deposits formation is carried out by assessing indirect parameters that do not allow determining the parameters of paraffin formation in various sections of the production tubing. These problems solution required development of a technology for remote diagnostics of organic deposits formation in the lift column, based on the laws of heat and mass transfer. The possibility of using this technology was confirmed by assessing organic deposits thickness in the WaxFlowLoop installation based on the change in heat and mass transfer and calculation of the average thermal conductivity of the formed deposits. The use of this technology will allow increasing the efficiency of oilfield equipment operation, reducing the accident rate of production, selecting more reliable methods for combating asphalt-resin-paraffin (ARPD) deposits with further evaluation of their effectiveness.
