SCADA Pipeline Monitoring Network
The operational network behind a pipeline SCADA system: field RTUs at pump and valve stations, the control centre, and a firewalled link to the business network.
Drawing diagram…
What this diagram shows
- RTUs and PLCs at each station report over a private radio or fibre WAN
- SCADA servers and the historian sit in the control-centre OT zone
- Business users see data only through a DMZ, never directly
Prompt used
Network topology for oil pipeline SCADA monitoring: pump stations and block valve stations have RTUs and PLCs with pressure, flow and leak sensors, linked over a private radio/fibre WAN to redundant SCADA servers and HMI operator consoles in the control centre. A historian stores time-series data. An industrial DMZ with a replica historian separates the OT network from the corporate IT network, with firewalls on both sides, following the Purdue model.

Permit-to-Work Lifecycle
The safety permit that controls hazardous work at a refinery or rig: request, risk assessment, isolation, gas testing, work and handback.
Upstream Digital Oilfield Architecture
A digital oilfield platform: wellsite sensors and SCADA, a production data historian, and engineering applications for surveillance and optimisation.
Well Data Ingestion Pipeline
How drilling and production data from wells is collected, quality-checked, stored and shared with engineering teams.
Refinery Process Flow
A simplified crude oil refinery: desalting, distillation, conversion units and blending into finished fuels.
Compressor Predictive Maintenance
How a gas compressor station predicts failures: vibration and process data, an ML model, and maintenance work orders before a trip happens.
Pipeline Leak Detection Alert
What happens when a pipeline leak detection system spots a possible leak: confirmation, valve closure, field response and regulator notification.
