This article discusses the experience of geological and geomechanical modeling at this field.</p> <p><strong>Aim:</strong> The purpose of this work is to consider geological and geomechanical modeling at the Urikhtau oil and gas condensate field as a method for further application in the design of well construction, taking into account the complexity of the geological structure of the field.</p> <p><strong>Materials and methods: </strong>To build a 3D model, data from seismic and geophysical surveys were used, as well as historical data to correlate calculations.</p> <p><strong>Results:</strong> The result of the modeling is the development of recommendations for the well profile, its design and optimal values of drilling fluid density, which will create a safe “drillability window” for well construction.</p> <p><strong>Conclusion:</strong> Geological and geomechanical modeling allowed us to develop key recommendations for well design, including optimizing drilling fluid density and ensuring wellbore stability.</p>geological and geomechanical modelingsafe drillability windowwell designdrilling fluidsdrilling fluid densityгеологиялық-геомеханикалық модельдеуқауіпсіз бұрғылау терезесіұңғыма құрылысыбұрғылау ерітінділерібұрғылау ерітіндісінің тығыздығыгеолого-геомеханическое моделированиебезопасное окно буримостиконструкция скважиныбуровые растворыплотность бурового раствора1.Basarygin YM, Bulatov AI, Proselkov YM.
