Identifying and fixing a broken sine wave filter in electric submersible pumps
Recurring ESP problems had no obvious cause. Irregular harmonic and voltage patterns at the surface VFD traced them to a failed sine wave filter.

We read the electrical signal of your ESP motor from the surface to catch problems early, without going downhole. Samotics is an established Electrical Signature Analysis company bringing proven technology to ESPs. We're inviting a small number of launch partners to shape it with us.
A failure means a workover, deferred production and often a well offline longer than anyone planned. By the time a problem in the equipment shows up in the operating data, it's often already well developed.
Read from the motor's electrical signal at the surface, alongside the data you already have.
Electrical Signature Analysis (ESA) reads the electrical signal of a motor and turns it into early, actionable warnings about developing faults. An ESP is driven by an electric motor, so that motor acts as a sensor for the whole system.
We measure the motor's current and voltage at 20 kHz at the switchgear or VSD. Nothing is installed downhole.
Electrical, mechanical and operational problems downhole all leave a trace in the electrical signal.
You get early, actionable warnings about developing faults, with reliability engineers behind every alert.
No well intervention, and nothing that fails along with the equipment it's meant to watch.
Because we measure at the surface, we can install on existing wells without pulling the ESP.
We've applied this principle successfully on other rotating equipment for years. ESPs are a new environment; the physics isn't new to us.
You get findings an engineer has already checked, not a stream of anomaly scores to work through yourself.
Designed to be independent of the ESP and drive manufacturer, giving one consistent view across the whole fleet, on new and existing wells alike.
The pump is running hard while you chase an early rate, and conditions change fast. We monitor continuously from the surface and flag developing electrical faults early enough to plan an intervention.
Rate has dropped and the pump now runs far off its best efficiency point, where downthrust and heat shorten run life. Following how the pump's load changes as the well declines, so you can plan around a trend instead of reacting to a failure, is something we want to explore with launch partners.
We've monitored ESPs in the field together with an ESP OEM and published the results in a peer-reviewed paper. We detected real faults from the surface, in live operations, alongside the existing downhole sensors. It shows the approach works on ESPs, not just in theory. And we're precise about what's proven and what isn't.
Gauges tell you how the well and the operation are behaving. We look at something different: the health of the ESP itself and the electrical system driving it. They answer different questions, so they work well together.
Those are useful signals, and they often show that something is wrong. What they rarely show is what's wrong and where it's developing. The electrical signal carries detailed information about the motor, the cable and the surface equipment, often earlier. And when a gauge fails, we're still measuring.
No, and we wouldn't advise it. They do a job we don't do. We add a layer of insight on the equipment that they can't give you.
No. We measure at the surface, so we can install on existing wells without pulling the ESP. No downhole hardware and no well intervention.
Our technology is designed to be independent of the ESP and drive manufacturer, because the physics is the same. We have the most experience with induction motors, so that's where we'd prefer to start. Running permanent magnet motors? Let's discuss your fleet.
That makes sense for the equipment from that OEM. Where we add value is across brands: one consistent view of equipment health across your whole fleet, whoever supplied the ESP or the drive.
Not today. Our focus is the condition of the ESP and its electrical system. Where operational issues affect the equipment, like gas problems, we can see their effect.
We have competetive launch terms for partners.
Launch partners work closely with our team and get a direct say in which ESP problems we focus on first. Instead of buying something designed for someone else, you shape it around your operation, with a team that's committed to making it work.
