Abstract: VNIGRI system of organic geochemical databases

SHIMANSKY, VALENTIN K., SERGEY G. NERUTCHEV, and SERGEY V. SMIRNOV, VNIGRI*

The source of the VNIGRI geochemical databases is a set of varied application-oriented paper-and-pencil immediate data (laboratory logs, card-files, archives, etc.), which were intensively collected during the 60th - 80th years of the specialized geochemical studies of the all main petroliferous basins of Russia.

It was necessary to organize a special procedure of the initial data revision and reliability estimation in order to integrate these heterogeneous information blocks into a unified system of computerized databases. The other problem was an elaboration of a complicated system of DB dictionaries and maps of sampling for end users.

Present-day system of the geochemical data bases as a part of the VNIGRI general computer relational database contains three main separate information blocks (DB "Source rocks," DB "Oils," DB "Gases") and two subsidiary blocks (DB "Thermometry" and DB "Hydrochemistry") with the special kinds of information for geochemical modeling. Up to the present the system includes the analytical information of about nearly 40000 samples from all Russian sedimentary basins.

The databases are a part of VNIGRI computer system "GEONOM", which is designed to perform the typical tasks of geochemical modeling. Besides the DB part, "GEONOM" contains: VNIGRI base of knowledge as a set of the general regularities, equations and coefficients, based mainly upon quantitative Balance Hydrocarbon Generation Model; experimental stepped thermolysis kinetic DB, including the information about the different types of the kerogen; model module, including program tools to calculate burial and thermal history, dynamic and intensity of the hydrocarbon product generation; electronic mapping module.

The GEONOM system was tested to estimate the hydrocarbon potential of Timan-Pechora basin.
