Specialists from the Rosneft Scientific Institute in Izhevsk have developed and tested an innovative method for assessing the corrosion rate of oil well equipment. The economic effect of using the innovation will average 1.4 million rubles per well over 5 years.
The essence of the new approach is to measure the corrosion rate using steel plates directly in the thermobaric conditions of wells. The process is carried out using special immersion probes, also developed by the institute’s specialists. Previously existing practices involve measuring the corrosion rate inside the cavity of ground infrastructure pipelines.
The developed method allows for precise determination of the minimum effective dosages of corrosion inhibitors, ensuring the target level of well protection*, increasing the period of trouble-free operation, and avoiding costly operations of lifting and dismantling well equipment.
The positive result of this work will reduce the overall costs of protecting the underground equipment of Udmurtneft named after V.I. Kudinov (the Company’s production asset). Work is currently underway to replicate the technology at other Rosneft facilities.
* according to the Interstate Standard “Corrosion of Metals and Alloys” ISO 9224-2022, the rate of general corrosion of equipment should not exceed 0.1 mm/year.
