1. What a field device sends over cellular
Smart oil and gas covers well monitoring, pipeline monitoring, fuel stations, and refineries. Pressure, flow, and video go up over 4G to SCADA and the cloud. Sites are often remote and have to stay explosion-safe, so the link has to hold and stay tightly controlled. SimtoLink supplies 4G to oil and gas companies, with a VPDN, a data pool, and an API into SCADA.
2. Wells, pipes, stations, and the refinery
The field covers wells, pipelines, and fuel stations. Bandwidth, and how quickly a pressure reading has to land, differ by site:
Well monitoring, production, and water injection
Pump jacks and water-injection wells report pressure, output, and operating conditions over 4G, for remote monitoring, fault warnings, and production tuning.
Pipeline monitoring and leak detection
Pipeline terminals and pressure sensors report pressure, flow, and acoustic signals over 4G, for leak detection and safety warnings.
Fuel stations and dispensers
Dispensers and level gauges report sales, stock, and transactions over 4G, for station management and a tighter supply chain.
The refinery and video
Refinery video and combustible-gas sensors report over 4G, for safety monitoring, remote patrol, and emergency command.
3. What the field link has to cover
- Unattended wells and stations: Pressure, level, and temperature on a well are collected as they change, into SCADA, with nobody on site.
- Pipeline integrity: Stress, corrosion, and temperature sensors are spread along the line. An abnormal reading raises an alarm and pins the spot.
- Maintenance before a stop: AI reads vibration and temperature on pumps and compressors, so a fault is seen before an unplanned shutdown.
- Explosion safety: Equipment has to carry ATEX or IECEx certification. The link uses a VPDN, and the data is encrypted end to end.
- Desert and offshore: 4G is weak on desert and offshore fields. Satellite has to sit alongside it so critical data does not drop.
4. Which SIM fits which site
Network, bandwidth, and power draw differ by site, so the SIM follows the device and the job. Use the table as a starting point:
| Use | Recommended network | Why it fits |
|---|---|---|
| Well RTU and SCADA terminals | 4G+VPDN/satellite | Production data, remote control, and unattended sites |
| Pipeline sensors | NB-IoT/4G | Integrity checks, leak alarms, and low power |
| Offshore platform communications | Satellite+4G | Worldwide reach, command traffic, and rescue |
5. How much data a field device uses
One device typically uses about 100–500MB a month. Video uses more. Pool SIMs by device type, keep 20%–30% spare, and use a VPDN to keep the link private.
6. Security for the field
Treat the link as high security. It needs a VPDN, end-to-end encryption, and an IP allowlist. SimtoLink provides the VPDN, a private APN, and real-name registration for the SIMs.
7. What SimtoLink would put on the field
For wellhead RTUs, pipeline monitoring, and station video, use a 4G IoT SIM. Fields are often remote, so the SIM has to be able to choose among operators. Pipeline monitoring has to report pressure and flow as they change. SimtoLink plans for 99.9% network availability, a choice of operators, a VPDN, and an API into SCADA.
8. Bringing a field online
Take an oil-and-gas rollout through these stages:
Pick the SIM by device type and check coverage on the target field. Set the VPDN or APN and the IP allowlist, and alert at 80% of the data allowance. SimtoLink stays with the project from the first well through production. Contact us for a plan built around those sites.
