Saltwater Disposal Well Monitoring
Saltwater disposal wells take produced water off operators' hands, and they run under strict permit limits on injection pressure and volume. Exceed the pressure limit and you risk the permit; overflow a receiving tank and you risk a spill. Monitoring keeps an SWD inside its limits and its tanks under control, remotely.
SWD monitoring software tracks injection pressure, injection rate, and receiving-tank levels at saltwater disposal wells, with alarms that fire before pressure exceeds the permit limit or a tank overflows - keeping the well compliant and spill-free from a cloud dashboard.
Staying Within Permit
An SWD permit caps maximum injection pressure and often daily volume. Continuous monitoring of injection pressure and rate, with an alarm set safely below the permit limit, gives the operator time to throttle or shut in before a violation - and the historian provides the pressure and volume record regulators expect. Pump and pressure data typically come from a PLC or RTU over Modbus, which Merobix reads.
Protecting Receiving Tanks and Uptime
SWDs also receive water into tanks before injection, so high-level and overflow alarms matter here as much as at a production battery. And because an SWD that goes down backs up water across the operators feeding it, a pump-fault or offline alarm delivered in seconds protects both the disposal well's uptime and everyone depending on it.
What You Get With Merobix
- Alarms that reach a person. SMS and email typically within a minute of a value crossing a threshold, with on-call escalation - included on every plan.
- Cellular edge, no server room. A gateway reads your devices and connects outbound to the cloud - no fixed IP, no VPN, no on-premise SCADA server.
- A built-in historian. Every reading is retained for trends, production reporting, and compliance records, queryable from any browser.
- One team for the whole stack. The same Texas team runs your SCADA and, if needed, programs your PLCs and builds your control panels.
Frequently Asked Questions
What does SWD well monitoring track?
Injection pressure, injection rate, and receiving-tank levels, plus pump status. Alarms fire before pressure exceeds the permit limit or a tank overflows, and the historian keeps the pressure and volume record for compliance.
Can monitoring help keep an SWD within permit?
Yes. An alarm set safely below the permit's maximum injection pressure gives time to throttle or shut in before a violation, and the historized pressure and volume data supports the record regulators expect.
Will I know if the disposal pump goes down?
Yes. A pump-fault or offline state triggers an alarm with escalation, protecting the SWD's uptime and the operators whose produced water backs up when it stops.
How is the SWD connected to the cloud?
A cellular gateway reads the SWD's PLC or RTU (typically over Modbus) and connects outbound to the cloud - no fixed IP or on-premise server. Merobix is managed and live in days.
