Oil-water emulsions are formed during oil production and represent a challenge in the oil industry. Because these emulsions can be very stable, they require the use of chemicals capable of breaking the emulsion and allowing oil recovery at the gas-oil separation plants (GOSPs). Our team at R&DC develops and tests smart, competitive biochemicals that are able to separate oil from tight emulsions. These biochemicals have potential applications in enhanced oil recovery and in oil-water separation at the GOSPs.
