Distribution characteristics of naphthenic acids, bituminous carbon, benzol, toluene, iodine, bromine, ammonium as well as iodine and permanganate oxidation in formation waters of Eocene and Cretaceous deposits has been studied. The link has been observed between some organic substances dissolved in water and micro components. For HC perspective estimation of Eocene and Cretaceous deposits relative values rather than absolute values of compositions of some components of dissolved in water organic substances and micro component has been used. Those are represented by the following rations, НЩ4/Нst, Оlod///Опер, Нst ///Нgen, Ойод///Опе/. Particularly, on the fields like Muradkhanly, Djarly, Karadjaly, Saatly and Tarsdallar the trend of increasing composition of naphthenic acids and ammonium - nitrogen coefficient is observed, as well as decreasing Ойод///Опер вя Нst //Нgen from nonproductive structures to productive ones while approaching oil - water contact. If used simultaneously, the data on composition of naphthenic acids in formation waters and some components of dissolved in water organic substances one can predict HC perspective of local structures. Reliability of some components of organic substances dissolved in water in relationship to oil content in Upper Cretaceous series varies from 46 to 72 %, as for gas content benzol and toluene are used (7072 %). Complex application of micro components and parameters of organic substances dissolved in water gives an opportunity to evaluate oil content of Eocene and Cretaceous deposits of local as well as regional structures.
