Along with well-known stimulation methods, such as modern methods of treating well’s bottom-hole zone, side tracking (drilling of lateral horizontal boreholes) is of great interest.&lt;/p&gt;&#13;
&lt;p&gt;The following works have been implemented Kalamkas field: a complex of geological, geophysical and field exploration; correlation schemes to track the lithology of the formation; clarifying structural maps and engineering maps; justifying activities to select one or more wells for horizontal drilling; hydrodynamic calculations and estimating their flow rate.&lt;/p&gt;</abstract><kwd-group xml:lang="en"><kwd>horizontal side tracks</kwd><kwd>technological efficiency</kwd><kwd>permeability</kwd><kwd>water cut</kwd><kwd>oil reserves involved</kwd></kwd-group><kwd-group xml:lang="kk"><kwd>бүйірлік көлденең оқпан</kwd><kwd>технологиялық тиімділік</kwd><kwd>өткізгіштік</kwd><kwd>сулану</kwd><kwd>алынатын мұнай қорлары</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>боковой горизонтальный ствол</kwd><kwd>технологическая эффективность</kwd><kwd>проницаемость</kwd><kwd>обводненность</kwd><kwd>вовлеченные запасы нефти</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Бейсеков С.С.
