Serzenga O. Scientific-method basis of layer fluid content and gas-oil contact position assessment with the use o well bore zone geo-electric model (the example of condensate fields of West-Siberian petroleum province).

Object of research - "water-drive" oil-gas condensate reservoirs, adjusted to tarragenie sediments; the purpose of research - work out methodological classification is to work out methodological classification basis of reservoir distribution info oil and gas bearing zones according to geoelectrical parameters of the round hole zone; research receptions - analyses of interpretation results of BKZ-BK-IK complex data, VIKIZ method, a PNK method, physical and chemical properties of layer fluids and perforation data; theoretical and practical results -the dependence of parameters of geoelectrical reservoir model upon layer fluid type has been determined. The location of oil and gas contact and gas cover thickness according to geoelectrical parameters of round hole zone have also been defined; the novelty entered - it was proved that oil-, gas- and water saturated reservoirs are characterized by a certain type of the curve of radial resistance distribution; the degree of introduction -it has been implemented; sphere (area) of use - geophysical enterprises dealing with either operative interpretation or calculation of hydrocarbon resources
