The reasons are the texture-structural, facies and lithological-petrophysical features of reservoirs of productive horizons of the field. In the future, it is planned to take samples in all new wells in order to determine the component composition of water for a reliable assessment of the current oil saturation, as well as constructing a mineralization map by area and horizons and reinterpreting well logging materials, conducting perforating and blasting operations for all wells.&lt;/p&gt;</abstract><kwd-group xml:lang="en"><kwd>field</kwd><kwd>saturation</kwd><kwd>oil recovery</kwd><kwd>carbonate sediments</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>месторождение</kwd><kwd>насыщенность</kwd><kwd>нефтеотдача</kwd><kwd>карбонатные отложения</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Шиланов Н.С., Хибасов Б.Б., Байтенов К.С.
