Insights
Practical knowledge. Better questions.
Practical technical insights on oilfield chemicals, demulsifier evaluation, bottle testing, chemical selection and specialty raw-material sourcing.
Separation
How to select a demulsifier for changing crude conditions
Begin with crude properties, water cut, process conditions and a clear performance target. Build a demulsifier screening plan around representative bottle-test conditions before field evaluation.

Testing & evaluation
Common bottle-test errors and how they affect decisions
A useful comparison needs more than a set of bottles. Document sample handling, temperature, dosage and the evaluation method.
