Well deparaffination unit WDU

Well deparaffination unit (WDU) is used for mechanical cleaning of oil-well tubing inner surface from asphalt-resin-wax deposits (ARWD) in the course of oil recovery by ESP and natural flow. WDUs differ by the way of setup on wellhead – they can be placed on wellhead using lubricator or on basement at 25-30 meters from the wellhead. WDUs also vary on control type – they can be semi-automatic or automatic. ELKAM supplies both onshore (including mobile) and offshore well deparaffination units.
