AUTOMATED PROCESS CONTROL SYSTEMS FOR OIL AND GAS PRODUCTION AND TREATMENT

The purpose of APCS creation is to enhance oil quality, obtain trustworthy information about processes at facilities, carry out operational monitoring and control of oil production and treatment processes, replace outdated automation facilities and control systems, enhance production safety, reduce labor intensity for processes control.

SOLUTIONS FOR OIL AND GAS PRODUCTION AND TREATMENT ENTERPRISES:

• APCS for well pads;
• APCS for booster pump stations;
• APCS for oil treatment units;
• APCS for gas treatment units;
• APCS for gas compressor stations;
• APCS for gas distribution stations;
• APCS for gas turbine / gas engine power plant;
• APCS for oil custody transfer stations of an oil producing company;
• APCS for reservoir pressure maintenance subdivision;
• APCS for tank farms;
• ACS for firefighting;
• Local control systems.

APCS FOR OIL AND GAS PRODUCTION AND TREATMENT INCLUDE ALL LEVELS OF CONTROL HIERARCHY.

• The lower level is primary automation facilities (process parameter transmitters, actuators, instrument converters, etc.), equipment with local automation systems and control stations. Primary automation facilities ensure conversion of process parameters into information signals, and control signals into control actions. The main purpose of control stations is gathering and primary processing of information, implementation of automatic control algorithms, programmable logic control, interlocks and alarms, data exchange with the upper level of APCS and implementation of commands from the upper level.
• The medium level is a level of subsystems. It includes software and hardware modules on the basis of programmable logic controllers (PLCs), input/output devices for analog and discrete signals, IS barriers, communication modules, networking hardware. This level is implemented through displaying information about a process and generating operational control commands from operator’s workstations located in control rooms of facilities (central production facilities, oil delivery and acceptance points, pump stations, gas turbine power stations).
• The upper level is a level of dispatcher monitoring and control. It ensures acceptance of information about the conditions at the facility from the medium and lower levels, process monitoring, acceptance of measured parameters trends, operational process control, archiving of events of the lower level and operator’s actions, etc. Some dispatcher monitoring functions at the upper level are transferred to the central (remote) office of the company.
