Automated system to control the technical condition of gas and gas-condensate wells located in the Russian Far North. A review based on exploitation data

Abstract

This report examines how to determine the technical state of gas and gas condensate wells, analyzes known methods to determine their state from operational data. Also the report examines how difficulty it is to use these methods in the Russian Far North. An innovative method is proposed that allows us to detect disturbances in the well in real-time, to diagnose the cause of these disturbances, and to take timely decisions to eliminate potential contingencies. The method is implemented on the basis of the existing system of telemetry of gas wells, as well as the information and control dispatcher system of the Enterprise. Thanks to this, it was possible to significantly reduce the costs, both work-hours and material, to create an automated system to control the technical condition of gas wells SOKTCGW according to operation data, and also promptly, in advance, take necessary measures to prevent abnormal situations.
