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
The system is designed to ensure scalability in hardware and
functionality to adapt to growing customer requirements better
integration with third party systems.
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.
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.
