Abstract: Western onshore fields are known as mature fields and the problems associated with mature fields are encountered in day to day operations. Water content of different fields are showing uptrend and field operator requires new products (Demulsifiers) to deal with the problems. Some of the field produces heavy while some produces paraffinic oil. To break this kind of emulsion (Heavy oil emulsion) it requires high temperature and higher doses of demulsifier. Demulsification of heavy oils is a well known issue and requires thorough investigation in terms of evaluation of the product at high temperature along with dose optimization to get better water quality after Demulsification. The paper deals with Demulsification studies of individual oil and studies on their mixes. Oils were treated with different demulsifiers at different temperatures. Product optimization studies were also taken up to select the best product which can be field implemented.
