Common Questions
Answer to some common questions:

1. Will higher treating temperatures always give better oil/water separation?

Not always. Higher temperatures usually help, but in some cases-particularly where very light oils or condensates carry waxes-additional heat has been seen to give negative results.

2. Will demulsifier treatment interfere with bactericide, scale inhibitor, or corrosion inhibitor treatment?

Only extremely rare cases.

3.Once the proper demulsifier is found for a given crude, can I expect it to work for the life of the production?

In some cases, the same formulation has been effective for tens of years. There exist those miserable system, however, which change so frequently that the demulsifier may have to be reevaluated every few days to weeks. These are normally new wells, and they may "chean up" after producing for some months.

4. What is the single most common reason that a demulsifier stops functioning in a system?

Chemical injection has been interrupted, or has dropped below the minimum effective treating level. The reasons include gas locking of chemical pumps, plugged filters, loss of power to chemical pump, plugged injection lines, leaking check valves, an-in some parts of the world-sabotage.
