METHOD FOR DETERMINING SIDETRACKING TRAJECTORY TAKING INTO ACCOUNT GEOLOGICAL RISKS Russian patent published in 2025 - IPC G01V11/00 E21B47/02 

FIELD: mining.

SUBSTANCE: invention relates to production of natural gas and gas condensate. Essence of the invention consists in the fact that determination of the project trajectory of sidetrack well drilling is performed with account of geological and technological parameters of the formation in the construction zone, namely formation pressure, porosity, permeability, effective gas-saturated thickness. At that, ranging of all technically implemented versions of trajectories of the sidetrack well of the well is performed, taking into account the forecast profile of production and expansion of the operating zone of the deposit. Obtained trajectory of sidetrack well is used when making geological and technological construction plan and then during construction of sidetrack well.

EFFECT: reducing the number of complications when influx is caused and during operation of the well, increasing final coefficient of gas and gas condensate extraction from the formation.
