The invention provides a method of inhibiting the formation of stable water in oil emulsions which are typically formed during the production of crude oil. The method involves the addition of one or more amphiphilic compounds which may comprise a hydrophilic backbone and hydrophobic groups attached thereto. The hydrophilic backbone may comprise polymerised units of one or more monomer compounds which may be selected from one or more of alkylene oxide, (meth)acrylic acid, acrylate, urethane, cellulose and vinyl alcohol. The hydrophobic groups may be attached to the hydrophilic backbone in one or more of the following positions: at one or more of the ends of the backbone, either regularly or randomly spaced along the length of the backbone, and as linking groups to link two or more portions of the hydrophilic backbone together.
