Oil Well pad telecontrol system
Introduction
The integrated oil well pad telecontrol system gathers information from oil well pads and transmits it to operator workstation for remote monitoring and control of geographically distributed well sites.
Typically, oil wells are distributed over a large area. The adjacent wells are united into a well pad. Group Metering Station (GMS) is used to determine the amount of crude, taken from the oil wells and control oil-field operations. The crude from wells comes to a Multi-Stream Switching Manifold (MSSM) through the pipelines connected to the GMS. The MSSM directs crude from one of the wells to a gas-oil separation plant (GOSP), while crude from the other wells comes to a common line. The GOSP separates gas from liquid.
Scope of Automation
- Oil wells combined into well pads;
- Well pumps, group metering station, valve manifolds;
- Container house utility subsystem;
- Fire and security alarm subsystem.
Main Features
- Crude telemetry: temperature, pressure, flow rate;
- Monitoring of MSSM, GMS, and valve manifolds;
- Monitoring of equipment statuses;
- Telecontrol of equipment;
- Data collection and transmission to the system server;
- Process visualization and human-to-machine interface via a set of standard graphical operator screens. Remote access via web interface;
- Storage of alarm, event and signal value history;
- Real-time and historical signal trends and events visualization;
- Generation of reports customizable in accordance with customer requirements.
The oil well pad telecontrol system is realized using a set of programmable logic controllers (PLC) and distributed control architecture. Redundancy of data networks is provided to ensure system availability and reliability. Wireless networks are commonly used. The system can be sheltered in a container house designed to furnish protection and normal operating conditions for the equipment installed inside it.
Benefits
- Flexibility
The system is designed to ensure scalability in hardware and functionality to adapt to growing customer requirements better integration with third party systems.
- Reliability
High reliability of telecontrol system is achieved due to the use of system components with high reliability ratings. Data communication networks availability is provided by redundant communication channels and specialized protocols.
- Functionality
The system components provide for additional operation modes (simulation, testing and masking) and other features, such as unauthorized access protection and event logging to monitor personnel actions.
