Oil & Gas Field Monitoring
The Oil & Gas Field Monitoring pack gives upstream production teams real-time visibility across wellhead gateways, flow meters, pressure sensors, gas detectors, storage tank sensors, separator controllers, and pump controllers. Five detection rules cover the alarm categories that matter in upstream production: high wellhead and casing pressure, H2S and LEL gas hazards, low oil flow, rising water cut, and tank overfill protection. When H2S climbs past 5 ppm at an unmanned wellsite, the alarm fires before anyone on the next shift arrives on site.
Five detection rules run continuously: high-pressure alerts catch wellhead and casing pressure excursions against configurable MAOP thresholds before blowout risk escalates; gas leak detection enforces OSHA H2S ceilings and LEL limits with severity-tiered alarms; well flow anomaly detection flags production declines and rising water cut; and tank overfill protection fires a critical alarm before crude reaches spill-risk levels. Pump and separator controls sit directly on the KPI dashboard so operators respond without switching screens. Three scheduled reports cover daily production, weekly operations, and monthly regulatory compliance.
Why Magistrala
Field devices connect over MQTT with per-client credentials, so a compromised sensor does not expose the rest of the wellsite network. Raw telemetry and validated data flow through separate channels, keeping detection rules clear of corrupted sensor records. One Well Operator template scales to any number of wellheads without duplicating dashboard configuration.

The challenge
Problems field operators deal with every shift
Wellhead incidents, gas hazards, and overfill events all have warning signals. The problem is having a system that catches them in time.
H2S above threshold at an unmanned wellsite with no one on site
An electrochemical H2S detector hitting the OSHA ceiling at an unmanned wellsite is a hazardous event with nobody there to respond. The alarm needs to fire before the next scheduled site visit.
A tank filling while the transfer pump is stopped overnight
When the transfer pump trips at midnight and nobody notices, crude keeps flowing into the tank. By morning the level is at 90% and the spill risk window is closing. An overfill warning at 85% gives enough time to act.
Wellhead pressure trending toward MAOP between manual shift checks
Pressure excursions that develop between manual checks can reach critical levels before anyone looks at the gauge. Continuous monitoring catches the trend at 1800 psi before it reaches 2200.
How it works
From sensor to action
Four steps from wellhead sensor to actionable alarm
Ingest
Wellhead sensors and controllers publish SenML payloads over MQTT to the Raw Telemetry Channel using per-device credentials. Every reading is saved immediately.
Validate
A data processing rule checks each incoming record against field safe ranges before alarm logic runs. Out-of-range sensor values are discarded before they reach detection rules.
Detect
Five rules watch clean data continuously. Pressure above 1800 psi fires a warning; above 2200 psi fires a critical. H2S above 5 ppm triggers a gas hazard warning. Flow below 50 bbl/d with the pump running raises a production anomaly. Tank above 85% triggers an overfill warning.
Report
Daily production, weekly operations summary, and monthly compliance reports go out automatically by email. Long-term production records write to PostgreSQL for regulatory reporting.
Key Applications
Where upstream operators deploy the Oil & Gas Field Monitoring pack
Wellhead production monitoring
Flow rate, gas-oil ratio, and water cut tracked continuously across producing wells. Daily production reports close the loop without manual data collection.
H2S safety compliance at unmanned sites
Continuous OSHA-threshold monitoring at wellheads and production facilities. Gas hazard alarms fire within seconds and reach on-call contacts by email before site personnel would detect the exposure manually.
Tank battery level management
Crude oil storage level monitored against two fill thresholds. Warning at 85% gives trucking schedulers a lead window before spill risk at 95%.
Separator and pump operations
Separator temperature and pressure trended for process upsets. Transfer pump status displayed and controllable from the KPI dashboard without navigating to a separate control interface.
Benefits
Why teams choose Magistrala for oil & gas field monitoring
The solution pack removes the integration work — so your team can focus on outcomes, not infrastructure.
- H2S and LEL alarms fire within seconds of OSHA threshold breach, giving operators time to respond before exposure risk escalates
- Wellhead pressure warnings at 1800 psi give time to investigate before the 2200 psi critical limit is reached
- Tank overfill warnings at 85% give trucking schedulers a practical lead window before the 95% critical alarm
- Device Health Monitor flags any silent field device within 10-20 minutes, protecting both safety coverage and regulatory data completeness
- Monthly compliance reports generate and deliver automatically, replacing manual production accounting assembly
- Per-client MQTT credentials isolate each field device so a compromised sensor cannot access others on the wellsite
- Tag-based Well Operator and Field Manager templates scale across multiple wells without duplicating configuration
FAQ
Oil & Gas Field Monitoring — Frequently Asked Questions
Open the High Pressure Alert rule in the Rules page and edit the threshold constants. The defaults (1800 psi warning, 2200 psi critical for wellhead; 1700 psi for casing) are typical Permian Basin tight oil parameters. Replace them with the values from your well's specific Maximum Allowable Operating Pressure design specification. The change takes effect on the next incoming message with no restart required.
Yes. Each field site is a Magistrala domain with its own device clients, channels, and rules. The Well Operator and Field Manager Summary templates use tag-based device references, so deploying a new well means provisioning its clients and assigning a group, not duplicating template definitions. A central operations view can aggregate alarm counts across all sites while individual site data stays isolated.
The Gas Leak Detection rule sends email notifications to configured recipients the moment the alarm fires. For escalation chains, add multiple recipients in the rule's email output. For SMS or Safety Management System integration, use the rule's webhook output to POST the event to your external system. The alarm stays open in the platform until it is acknowledged or the H2S reading returns below threshold.
Either works. Each device type has its own client credentials, so sensors can connect directly if they have MQTT capability. In most field deployments, all sensors route through the Wellhead Gateway: a single TLS connection handles the entire wellsite stream and the gateway can buffer readings during brief connectivity outages. Both approaches deliver identical telemetry to the Raw Telemetry Channel.
