PMA team reviewing TD-120 online oil-in-water monitoring data

Produced-Water Oil Monitoring

Track oil carryover through produced-water treatment and combine continuous trends with targeted sample checks.

Understand what is changing across treatment

Produced-water oil monitoring can help operators investigate carryover, compare treatment stages and follow changes in the oil content of a water stream. Before selecting an instrument, define whether you need a continuous trend, a local alarm or periodic samples for treatment checks.

PMA can review a TD-120 installation for online monitoring and TD-550 or TD-560 portable analysis for collected samples. Selection depends on the target oil and the measurement task. Crude composition, salinity, solids, treatment chemicals and changing process conditions should be included in the application review.

TD-120 online oil-in-water monitor

Continuous treatment trends

Review the TD-120 when the aim is to follow oil changes at a selected process point and provide data to a plant monitoring system.

TD-550 portable oil-in-water analyser

Collected-sample checks

Consider the TD-550 for suitable crude-oil targets. Where lighter hydrocarbons are involved, review the TD-560 with PMA.

Build a monitoring plan around your treatment train

Choose meaningful sampling points

Decide which inlet, intermediate or outlet points answer the operating question. Samples taken at different locations or times may describe different conditions; record treatment status when comparing results.

Use representative calibration

Provide a description or representative sample of the oil being measured and the expected concentration range. A calibration from a different oil or water matrix may not give the same relationship between fluorescence and concentration.

Separate process control from reporting

Use trends and sample checks to support investigation of treatment performance. If a laboratory method is required for formal reporting, retain that method and establish any comparison using representative paired samples.

Frequently asked questions

Can oil monitoring help assess treatment performance?

Comparing representative readings before and after treatment can help operators investigate changes. Sampling time, calibration and the water matrix must be considered before attributing a difference solely to treatment performance.

Should produced-water monitoring be portable or online?

Use online monitoring when continuous visibility or an alarm is required at a defined point. Portable analysis is useful for checks across several locations and investigations. Some sites benefit from both, with a documented comparison procedure.

Can one instrument measure every produced-water stream?

A universal fit should not be assumed. The oil composition, concentration, salinity, solids and sample conditions need review. PMA can discuss the optical configuration and practical sampling requirements before a recommendation is made.

What should I include in an enquiry?

Include the crude or hydrocarbon description, treatment process, sampling points, expected range, temperature, pressure and current laboratory method. State whether the result will drive an alarm, a treatment decision or a reporting comparison.
