Predictive Maintenance/Oil & Gas

Predictive maintenance built for remote sites and harsh service.

We build ML-supported digital twins for upstream, midstream, and refining assets. Forecast the life-limiting physical parameters of pumps, compressors, turbines, and pipelines, instead of guessing at Remaining Useful Life from biased shutdown history.

  • Edge deployment for offshore platforms, remote wellsites, and pipelines without reliable internet
  • Soft sensors for downhole conditions and stream composition you can't safely measure online
  • Focused digital twins around ESP motors, compressor stages, gas turbine hot sections
  • Operator UIs that fit on existing CMMS and SCADA screens, with named owners and response SLAs

Where you are vs where you could be

From scheduled rod-pulls to forecast-driven operations

Most upstream and midstream operations run on a mix of run-to-failure for low-criticality assets and hour-meter preventive servicing for everything else. The work that pays back fastest is on critical rotating equipment: forecast the parameter that ages the asset, advise on the operating point that extends life.

TIER 01

Reactive

Run to failure. ESP fails downhole, gas turbine trips, pipeline anomaly only caught at flow meters. Repair logistics dominate the cost.

TIER 02

Preventive

ScheduledHour-meterTime-driven

Calendar overhauls and hour-meter servicing. Better than reactive, but you over-service some assets and miss the ones drifting fastest in real conditions.

TIER 03

Condition-basedPrescriptive

Forecast a critical physical parameter with a known engineering limit. Use the parameter's own history, your operating setpoints, and leading indicators from upstream sensors.

The honest version

Why most predictive maintenance projects don't deliver

RUL is a virtual, biased variable

Remaining Useful Life is calculated from when assets actually stop. But pumps and turbines stop for many reasons that aren't wear-related: scheduled overhauls, demand swings, undetected fabrication defects, business decisions. Training a model on biased shutdown history teaches it the bias, not the failure.

Sensor noise creates false alarms

Sensors fail, drift, and live through years of vibration, heat, sand, and corrosive service. A model relying on small deviations between sensors fires alerts when the measurement hardware ages, not when the equipment does. Operators stop trusting it within six months.

No causality, no explainability, no adoption

"The model says pull this ESP in 17 days" doesn't survive contact with a production engineer who has run that field for a decade. Without a physical reason tied to a measurable parameter, predictions get ignored.

Cloud-only systems don't fit the field

Many predictive maintenance platforms assume always-on connectivity. Offshore platforms, remote wellsites, and pipelines often don't have it. Models that can't run locally, with sync windows when connectivity returns, don't reach production.

The model only reflects what we give it. When the data carries the real behavior of the system, the predictions make sense. When the data is messy or misunderstood, the output becomes noise. This is where predictive maintenance projects are won or lost. Not in the algorithm but in the understanding.

Our approach

Forecast the parameter that ages the asset.

A digital twin, in our usage, is a model of one or two physical parameters that limit the asset's life, with limits the engineering team already understands. ESP motor temperature has a thermal envelope. Gas turbine hot-section TIT/EGT has a blade limit. Compressor polytropic efficiency has a degradation threshold. Forecast those, and you forecast life directly.

The forecast uses three input families. Each one carries different signal.

Critical parameterforecast: T+1...T+H1. The parameter itselflagged history (lag 1, 2, ...)2. Operating setpointsload, frequency, fuel mix3. Leading indicatorsupstream lagged signalsCompare against engineering limitcycles remaining + actionable knobs

Why this beats RUL prediction

01

Physical, measurable, validatable

Production engineers see the forecast against today's actual reading. Trust builds in weeks, not quarters.

02

Causal and explainable

Each prediction ties to specific operating setpoints and upstream signals. "Why did it predict this" has an answer.

03

Actionable

Vary an operating setpoint within tolerance, see the forecast shift. The system advises the next operating move, not just an alarm.

Use cases in oil & gas

Four critical parameters we forecast directly

Each one anchored to a parameter with a known engineering limit, scoped tightly enough to deliver a working PoC in 6 to 8 weeks.

USE CASE 01

Electric submersible pump (ESP) failure prediction

FORECASTSMotor temperature trajectory, vibration trend
CONTROL KNOBSPump frequency, gas-handling settings, intake conditions
LIMITMotor thermal envelope, mechanical vibration class

ESP pull jobs are expensive, especially offshore. We forecast motor temperature and vibration trends from frequency, intake gas content, and downhole conditions, then advise on operating points that extend run-life and on early intervention windows that beat unplanned failure.

USE CASE 02

Gas turbine hot-section life management

FORECASTSTurbine inlet / exhaust gas temperature (TIT/EGT)
CONTROL KNOBSLoad, fuel mix, fan speed demand, ambient compensation
LIMITHot-section blade thermal limit

Gas turbines on platforms and at compressor stations are limited by hot-section wear, which tracks directly to TIT/EGT. We forecast that parameter from load patterns and operating setpoints, and identify the load-mix combinations that extend blade life without giving up throughput.

USE CASE 03

Compressor station polytropic efficiency

FORECASTSPolytropic efficiency drop, discharge temperature trend
CONTROL KNOBSAnti-surge margin, load split across units, intercooler flow
LIMITSurge envelope, mechanical thermal limit

Compressor degradation creeps in through fouled internals and tip clearance growth. We forecast efficiency drop from discharge conditions and load patterns, then prescribe load shifts and anti-surge tuning that protect throughput while extending overhaul intervals.

USE CASE 04

Pipeline integrity and refinery heater tubes

FORECASTSPressure / temperature deviation, tube skin temperature
CONTROL KNOBSThroughput, drag reducer dosing, firing rate, excess air
LIMITIntegrity bound, tube creep envelope

Pipelines and heater tubes age with thermal and stress cycles. Anomaly detection catches deviations from normal operating envelopes; soft sensors infer tube skin temperatures where direct measurement isn't available. Predictions integrate with the CMMS so flagged anomalies become work orders with named owners.

From forecast to action

The AI Advisor pattern

Once you forecast a physical parameter, you can vary the operating setpoints within their safe envelope and watch the forecast move. That turns the model from an alarm system into an operating advisor: change the pump frequency, the turbine load, the anti-surge margin, and see the projected life of the asset shift in real time.

01

Dynamic parameter adjustments

Real-time setpoint modification, all in inference mode. Useful in the field, where every "what if" matters.

02

Operational mapping

Implement operating envelopes that keep parameters inside their boundaries and preserve the relationships between them.

03

Operator-facing advisor

Surface the top one or two control adjustments that extend run life without compromising throughput or safety.

Visualization style based on Adam's published model output. The aviation example translates directly to industrial gas turbines: lower fan speed demand extends the hot section life; pushing past the envelope accelerates blade wear.

The interface layer

A System of Intelligence, not another dashboard

A forecast that nobody acts on doesn't change anything. The pattern that works in the field isn't another grid of widgets to check every morning, it's an intelligent notification layer that surfaces what changed, where to look, and what the reasonable next step is. Especially valuable for remote operations where attention is scarce.

PRINCIPLE 01

Notifications, not navigation

The system pushes when something matters. No daily ritual of scanning SCADA mosaics or hunting through emailed reports for the one well, pump, or compressor that's drifting.

PRINCIPLE 02

Surface what changed

Each alert points to the specific asset and parameter that moved. The recipient doesn't have to reverse-engineer what triggered the notification across hundreds of wells or tens of compressor stations.

PRINCIPLE 03

Suggest a reasonable next step

Not "this is anomalous." Instead: "ESP motor temperature is drifting toward thermal envelope; consider reducing pump frequency by 3% or scheduling a workover within the operating window."

It's not a dashboard for the sake of a dashboard. It's an intelligent notification-based system that shows you where to look, and what the reasonable next step is. You don't check every dashboard every morning. You get a notification when something needs your attention.
