Well Dewaxing Unit
“UDS-TEKHNO” dewaxing unit is designed for fully automated mechanical cleaning of tubing internal surface using a scraper from asphaltene, resin, and paraffin deposited in ESP operated and flowing wells.
UDS prevents formation of asphaltene, resin, and paraffin plugs, restores and maintains a stable well fluid rate.
The unit has an automatic, semiautomatic and manual cleaning modes:
SUL-01 control unit ensures operation of UDS - Tekhno dewaxing unit in an automatic mode with parameters set by operator using the control unit
In a semiautomatic mode the control unit enables running in, stopping, and pulling scraper out of the well
The unit has a modem for transmitting data to an online monitoring server and controlling UDS operation via GSM mobile network
