Application of geomechanical modeling tools to create a reservoir pressure model and reduce drilling Accidents at a oilfield in the northern part of the Yamal-Nenets Autonomous District

The main purpose of this work is to create a model of reservoir pressure to reduce accidents during drilling (gas occurrence, drilling fluid absorption). The field has a complex geological structure, an increased coefficient of abnormal reservoir pressure in the target formations and zones of local increase in reservoir pressure The features of the oildield are: • Growth of reservoir pressure in the Achimov strata • Presence of a zone of increased anomaly coefficient in the Ach 17-0 formation (1,7–1,9) To solve these tasks, a combination of geomechanics and geological modeling methods is used
