MICROELEMENT CRITERIA IN ASSESSING THE PROSPECTS OF OIL AND GAS CONTENT OF THE PRE-JURASSIC DEPOSITS OF WESTERN SIBERIA
At present, in Russia and abroad, geochemical indicators of oil and gas assessment are becoming increasingly important. Investigations of the trace elements (TE) composition of the oils and organic matter (OM) of rocks have gone beyond the framework of purely theoretical developments and acquire a significant applied value. Information on the content of TE in naphthydes is taken into account in a wide range of fields of knowledge, and most important for us, is an effective and necessary tool in solving the problems of oil and gas prospecting geology. In the article, the TE-criteria are considered that, combined with other indicators, make it possible to assess the prospects of the oil and gas potential of the lower structural floor of the West Siberian oil and gas basin (OGB).
