Demulsifier Bottle-Test Workspace

Use this demulsifier bottle test workspace to evaluate up to 30 candidates plus untreated and incumbent controls. Record custom reading times through 24 hours and produce a structured comparative ranking. All calculations run locally in the browser; entered data is not uploaded or stored.

Up to 30 candidatesCustom read timesLocal data only

1. Test conditions

Project / sample ID

Test temperature (°C)

Bottle volume (mL)

Expected water (mL)

Comparability check: use the same representative sample, bottle volume, temperature, mixing procedure, timing and analytical method for every candidate.

2. Candidate observations

Enter separated-water volume at each reading. Rag and final BS&W are penalties; cleaner separated water receives a higher quality score.

Reading schedule

Add any reading time from 1 minute to 24 hours. Times are sorted automatically.

Candidate capacity

5 / 30 candidates, plus untreated Blank and Incumbent controls.

Ranking must be reviewed together with reproducibility, final oil specification and produced-water quality.

Scoring logic and limitations

The comparative score rewards early and final water separation and cleaner water, while penalising rag-layer thickness and residual BS&W. It is a screening aid—not a product approval criterion. A technically acceptable winner must remain reproducible and should not trade better dehydration for unacceptable water quality, interface behaviour or downstream risk.

Use an untreated blank and the incumbent product.
Bracket the field dose rather than testing one concentration.
Record temperature and sample history.
Confirm the preferred candidate in a controlled field trial.
