What Is SCADA (Supervisory Control and Data Acquisition)?
SCADA (Supervisory Control and Data Acquisition) is the real-time monitoring and control technology used across oil and gas operations to collect, transmit, and display data from remote field equipment. A SCADA system consists of sensors and instruments at the well or facility level, remote terminal units (RTUs) or programmable logic controllers (PLCs) that aggregate local data, and a central communication network that transmits data to a control center or cloud platform.
What Does SCADA Monitor in Oil and Gas?
- Well production data: Flow rates, tubing/casing pressures, temperatures, pump speed, motor current
- Tank levels: Surface storage tank volumes for oil and water
- Pipeline conditions: Line pressures, flow rates, and valve positions
- Compressor performance: Suction/discharge pressures, RPM, fuel consumption, motor amps
- Separator conditions: Pressure, temperature, and level in production separators
- Pump jack data: Motor current, pump speed, stroke count, dynamometer data
How SCADA Data Flows in Oil and Gas Operations
SCADA data is collected at the wellhead or facility level by RTUs or PLCs, then transmitted via radio, cellular, or satellite to a central server or cloud-based historian. Field operators and engineers can access SCADA data through workstation dashboards or mobile apps. Most modern SCADA systems store data at 15-minute to hourly intervals, generating enormous volumes of time-series data across large well portfolios.
Limitations of SCADA Alone
SCADA captures operational data in real time, but it doesn't automatically reconcile with other data systems (production accounting, tank gauge tickets, plant statements), file regulatory reports, or diagnose complex equipment problems. SCADA data alone is not the same as production reporting data — the two must be reconciled before submission to regulatory agencies.
How AI Unlocks SCADA Data Value
AI can analyze SCADA time-series data to detect anomalies, predict equipment failures before they occur, optimize pump settings in real time, and automate the reconciliation of SCADA data with accounting and reporting systems. Collide integrates with existing SCADA historians to add an intelligence layer on top of operational data.
