An overview of oil drilling and production monitoring system using SCADA automation in Oil and Natural Gas Corporation Ltd.

Oil and Natural Gas Corporation is a leading Exploration and Production Company in India. In order to manage, monitor and supervise its vast machinery and sensor data at its diverse drilling and production sites, it needs an automated supervisory system. ONGC uses the industry-popular Supervisory Acquisition and Control System (SCADA in short). Here specialized controller systems convert sensed on-site parameters into digital signal which is transmitted to various regional tiers via VSATs and leased lines. Remote Supervision can thus be done by engineers and necessary action taken. This paper discusses the SCADA system being used by ONGC to monitor its field devices.
