…The forecast of geological conditions and overpressure zones made by the company's engineers, including below the current bottom, for the first parametric ultra-deep well of the Gydan Peninsula with a depth of 6126 m, based on geomechanical modeling for four analog wells located on the territory of the Yamal-Nenets Autonomous District, largely contributed to the prevention of accidents at the most difficult stage of drilling the parametric well Gydanskaya 130 in extreme geological conditions.

Geomechanical modeling with rapid updating of the model, calculation of the wellbore stability, as well as recommendations on drilling procedures and technological filling of the well construction process made it possible to timely identify the risks of geological complications, explain the nature of their occurrence and perform technically possible preventive measures…
