A variety of chemicals mainly of an organic nature are used in enhancing production of oil and gas and mitigating problems associated with the production of oil and gas. Such production chemicals fall in to the following broad categories.

Demulsifiers, or emulsion breakers, are a class of specialty chemicals used to separate emulsions, for example, water in oil. They are commonly used in the processing of crude oil, which is typically produced along with significant quantities of saline water. This water (and salt) must be removed from the crude oil prior to refining. If the majority of the water and salt are not removed, significant corrosion problems can occur in the refining process.

Demulsifiers are typically based on the following chemistry:

Acid catalysed phenol-formaldehyde resins
Base catalysed phenol-formaldehyde resins
Epoxy resins
Polyethyleneimines
Polyamines
Di-epoxides
Polyols
dendrimer
The above are usually ethoxylated (and/or propoxylated) to provide the desired degree of water/oil solubility. The addition of ethylene oxide increases water solubility, propylene oxide decreases it.

Commercially available demulsifier formulations are typically a mixture of two to four different chemistries, in carrier solvent(s) such as xylene, heavy aromatic naphtha (HAN), Isopropanol, methanol, 2-Ethylhexanol or diesel.

Advantages:

Quickly reduce water-in-oil to levels of 0.1 to 0.5 percent

Provide sharper interface between the two phases for easier separation

Remove more water to get closer to commercial crude oil specifications

Deliver high performance in heavy oil, addressing problems arising from high viscosity

Highly efficient at low temperatures, reducing he expense needed to heat oil

Reduce oil-in-water levels for easier discharge or reinjection of water.
