.... The second application of UAS we are evaluating is for offshore in situ burning. Herders are a product that has been under development for several years to enable in situ burning without the need for fire-resistant booms. Herders are made of surfactants that cause an oil slick to rapidly contract...

This illustrates the difficulty of analysing surface-active substances in produced water. The nitrogen-in-water analysis is not suitable for the produced water sample, due to the interference...

... been demonstrated effective in laboratory and field tests on oils previously considered undispersible. The key to the effectiveness of this product is the selection of solvents which can remain in the oil film and resist extraction by seawater long enough to enable the surfactants to be effective...

... J. M. Getliff and S. G. James, SPE, Dowell division of Schlumberger Evaluation and Production Services (UK) Ltd. Abstract Alkyl-phenol ethoxylates (APEO) are a class of surfactants which have been used widely in the drilling fluid industry. The popularity of these surfactants is based...

Experimental results of this investigation confirm that electrical resistivity of such emulsions vary widely with temperature, brine and oil salt contents, amount and type of surfactants and co-surfactants used. This indicates that any correlation between...

... ABSTRACT This paper presents a survey of marine toxicity and biodegradability data for surfactants used in the petroleum industry. Surfactants are key chemicals in the formulation of products such as emulsifiers, demulsifiers, dispersants and inhibitors. They are also used directly as foaming...
