Authors: E.V. Stremichev, B.V. Belozerov (Gazpromneft NTC LLC, RF, Saint-Petersburg), E.V. Zagrebelniy (Gazpromneft-Orenburg CJSC, RF, Orenburg), R.R. Bakhitov, A.A. Artamonov (Gazpromneft-Razvitie CJSC, RF, Moscow)

Key words: reservoir, well survey, reservoir properties, reservoir criteria, the structure of the pore space.

Cross section of tsarichanskoye field in the gross interval of the Dkt productive strata refers to the complex type. This is associated with abnormal rock radioactivity, complex material composition, strong lateral variability of the section, the presence of mixed-layers clay in the section. The combination of all these factors creates a serious problem in the interpretation of the lithological composition of the rocks, forming the strata, reservoirs separation according to well survey data. To solve this problem the well survey materials, laboratory core studies, field-geophysical studies and also the experience of experts, studying the given problem, were used.
