Oil and gas production handbook - Process Control and ...

are logged and compared with reference values to detect abnormal conditions and
indicate when preventive maintenance is required or an equipment fault occurs (i.e.
maintenance triggers)
For other process equipment such as valves the system can register closing times,
flow and torque. A valve which exhibits a negative trend in closing time or torque
(“sticktion”) can be diagnosed. Generally “maintenances triggers” are based on
equipment diagnostics to predict when preventive maintenance is required. Fieldbus
mounted transmitters and actuators are particularly well suited to condition
monitoring diagnostics.
Maintenance support functionality will plan maintenance based on input from
condition monitoring systems and a periodic maintenance plant. This will allow the
system to schedule personnel for such tasks as lubrication or cleaning, and plan
larger tasks such as turbine and compressor periodic maintenance.
5.1.7 Production Information Management Systems
(PIMS)
A specific information management system
can be used to provide information about the
operation and production of the facility. This
can be a separate system, or an integral part of
the control system or SCADA system.
For Oil and Gas, PIMS functionality includes:
• Oil & Gas Production Reporting.
• Safety Management
• Maintenance
• Operator Support
• Overall systems integration and
external
• Historical data including post failure “flight recorder” data
Some of the application provided by a PIMS system may be:
• Well Test application.
• Production Allocation (oil/gas/water) based on Well Test results.
• Metering data from integrated metering system.
• Volume in storage cells & consolidation of produced stored and dispatched
volumes.
• Safety data, alarms & operators comments.
• Drilling data acquisition and drilling data logging
