Ways to improve interpretation of well data for operational modeling of horizontal wells

Authors: A.M. Khusainova (BashNIPIneft LLC, RF, Ufa)

Key words: reservoir properties, geophysical logging, geophysical methods, reservoir.

The article is devoted to a topical problem of justifying methods of well logging data interpretation at small sectors of deposits in specific geological conditions in the absence or limited provision with core samples. This technique can reliably estimate reservoir properties and oil saturation of reservoir rocks in wells needed to perform geological and hydrodynamic modeling in Republic of Bashkortostan.
