The trial-and-error method of choosing an optimum demulsifier out of a wide variety of demulsifiers to effectively treat a given oilfield water-in-oil emulsion is time-consuming. To minimize this, the use of the dielectric constant as a criterion for screening, ranking and selection ofdemulsifiers for emulsion resolution was investigated. Dielectric constants of emulsions and demulsifiers were measured using a portable capacitance meter (Harris Model), while bottle tests were conducted according to API specifcation.
The results show that the dielectric constants can be used effectively to screen and rank demulsifiers while a confirmatory bottle test is conducted on the best demulsifiers to assist in the rapid selection of the most effective demulsifier. This procedure will save time and cost in the petroleum industry.
On the basis of this study, a stage-by-stage screening procedure is presented.
