1. Automated Dewaing Unit has been used for 30 years and showed great performance in CIS and non-CIS Regions.
2. Due to specific automation configurations and design solutions, Automated Dewaxing Unit can be stable in operation both on wells equipped with ESP (electric submersible pumps) and on flow-rate, intermittent and gas-lift wells.
3. SA Unit has a very wide range of controlled parameters and settings, which allows the Customer to improve the cleaning process and achieve maximum economic effect.
4. SA Unit is firstly intended for automation of the process of mechanical tubing cleaning from asphaltene, resin and paraffin deposits. It allows the Customer’s specialists to work not only in automatic mode, but in semi-automatic and manual modes as well.
All MDSA winches are designed to be connected to the Customer’s telemetry system and to Debit-E Express Telemetry system via a free RS-485 port over MODBUS RTU.
Express Telemetry system by Debit-E:
— Allows for monitoring the winch operation in near real-time mode;
– Allows for viewing summary information about all connected winches (status, depth, power, speed, communication quality etc.) on 1 page;
— Allows for obtaining winch operation graphs for an arbitrary time interval;
— Allows for sending text messages about the winch operation process to specified telephone numbers;
— Allows for remote MDSA control: lifting and locking in the lubricator before the service team arrives, unscheduled startup of a cleaning cycle, lifting from error state, etc.
— Allows for monitoring and control from any device connected to the Internet (computers, tablets, or smartphones) without installing additional software;
— Allows for remote changing of setpoints;
— Allows for differentiating access rights in the Personal Account;
— Allows for connecting non-standard functions (operator presence control, text message about cabinet opening, sensor polling, and other telemetry data transmission, etc.).
