Oil and Gas Production SCADA Application
Oil and Gas Wells
There are two main types of wells: Natural Flow and Artificial Lift wells.
Monitoring and remote control requirements depend on the type of well. For
natural flow well, surface process variables like flowing/casing pressure and
temperatures and the position of the flowing valve need to be monitored and gas
wells include compensated flow calculations. Remote control is limited to the
shutdown valve. For artificial lift wells, additional monitoring and control is
required to be able to supervise motor or gas lift valves and be able to control
those devices.
Compressor Stations
Compressor Stations are responsible in pipeline systems for maintaining the
appropriate pressure levels needed to deliver gas at the destination locations.
Multiple compressor stations are typically needed in a gas pipeline and the
communication to a central location is key ensure coordination and safety of the
operation.
Valve Stations
An important element in the safe operation of a gas or liquid pipeline is the block
or segmenting valves. These valves are mainly responsible for shutting down
segments of the pipeline to isolate leaks or ruptures. Local and remote control
capabilities as well as data acquisition functions to be able to collect process
information along the pipeline (Pressure, temperature, flow, and valve position)
are the main requirements of this application.
Pump Stations
Operate by maintaining system pressure or matching flow demand. Multiple
pump stations connected to the pipeline and communicating back to a central
location are used to deliver crude oil or products to refineries and terminals.
