Purpose
The use of GSM-modems allows real-time:• Remote adjustment of well operation parameters (e.g., increase or decrease the frequency of motor supply voltage);
• Quick analysis and error cause removal;
• Remote reading of archives of the controller and installation of more advanced versions of the software;
• Remote unblocking and start of the installation.
Application
Oil and gas production facilitiesAdvantages
• Possibility of remote control of the well operation• Reduced labour and transportation costs when fulfilling emergency requests
• Ease of implementation and flexibility of settings
Design
• GSM modem • AntennaWork principle
The modem receives a digital signal from the user through a special programme, converts it to analogue, and transmits the request to servers that store the necessary information, then receives a response to the sent request in analogue form, converts it to digital and transmits it to the remote access programme.Technologies
