METHOD OF IMPROVED PLANNING OF THE HEIGHT OF A HYDRAULIC FRACTURING CRACK IN A LAYERED ROCK OF UNDERGROUND FORMATION Russian patent published in 2018 - IPC E21B43/26 E21B43/247 

FIELD: drilling of soil or rocks; mining.

SUBSTANCE: embodiments in the context of the present invention relate to a method of hydraulic fracturing a subterranean formation intersected by a wellbore, including obtaining the characteristics of a given formation using the measured formation characteristics, including mechanical characteristics of geological boundaries, identification of fracture height of the formation, the identification including the calculation of the contact surface of the fracture of the fracking with geological boundaries, and hydraulic fracturing of the formation, wherein the fluid viscosity or fluid flow rate or both are selected using calculations.

EFFECT: embodiments in the context of the present invention also relate to a method of hydraulic fracturing a subterranean formation through which a wellbore passes, including measurements of the formation containing the mechanical properties of geological boundaries, obtaining formation characteristics using measurements, calculating fracture height of the formation using formation characteristics, calculation of the optimum fracture height using measurements and comparing the optimum fracture height with the fracture height of the formation.
