NATURE OF NAPHTHENIC ACIDS IN BAKU CRUDE OILS AS A FUNCTION OF THE DEPTH OF OCCURRENCE

The author analyzes data on the contents of naphthenic acid in crude oils. Characteristics and properties of naphthenic acids in oils of adjacent formations are compared. The final conclusion denies the existence of any general relationship between the content of naphthenic acids and the depth of occurrence of oils of the deposits of the Apsheron Peninsula. --Royer and Roger, Inc.
