METHOD FOR ANALYSIS AND DESIGN OF STIMULATION OF AN UNDERGROUND FORMATION Russian patent published in 2020 - IPC E21B43/26 G06F17/00 

FIELD: mining.

SUBSTANCE: group of inventions relates to methods of stimulating a subterranean formation and predicting distribution of material during and after stimulation of a subterranean formation. Method comprises obtaining input processing data of the formation, simulating transfer of at least one material in the treatment of the formation. Determining and preparing the treatment design and processing the formation in accordance with the selected processing design. Simulating transfer of at least one material in a reservoir treatment project using a model, which includes the assumption that for each time stage of treatment of formation there are known a velocity field for transfer of at least one material and geometry of the stimulation zone, and calculating at least one physical quantity describing the material distribution at each time step using the Lagrangian approach.

EFFECT: technical result is higher efficiency of treatment of formation.
