About two third of petroleum production of every oil field exists in the form of water in oil  emulsion.  The emulsion  stability  results  from  the  presence  of  interfacial  barrier preventing  coalescence  of  the  dispersed water  droplets.  This  is  due  to  the  present  of polar components such as asphaltenes, resins, wax and naphtenic acids in  the crude oil. It has been  reported  that  the combination of oil-soluble demulsifiers and water-soluble demulsifiers  produced  great  result  in water  separation.  From  the  screening  process  of single  oil-soluble  demulsifiers,  the  most  effective  chemicals  as  demulsifier  are hexylamine and dioctylamine while butanoic acid, and formic acid are the most effective chemicals  in water-soluble group. This new  formulation was  found  to be effective  for demulsification  of water-in-oil  emulsion  of Dubai, Miri,  and Masilah  fields  emulsion system. In order to obtain better understanding and results, optimizing on agitation and temperature  conditions,  the  mechanism  demulsification  study  are  recommended  for further study. 0aEmulsions
