A method for controlling hydrocarbon recovery to improve well interactions while preventing excessive strain or stress-induced well deformations and mechanical failures is described. The method incorporates a systematic, transient analysis process for determining the formation effective displacement, stress and excess pore pressure field quantities at any depth within a stratified subterranean formation resulting from the subsurface injection and/or withdrawal of pressurized fluids.
La présente invention concerne un procédé de régulation de la récupération d'hydrocarbures pour améliorer les interactions en puits tout en prévenant els déformations de puits et défaillances mécaniques imputables aux contraintes. Le procédé comporte un procédé d'analyse transitoire permettant de déterminer les niveaux quantitatifs du déplacement effectif de la formation, de la contrainte et des champs de pression des pores en excès à n'importe quelle profondeur dans une formation souterraine stratifiée par suite d'injection et/ou de retrait de fluides pressurisés sous la surface.
