Title (EN) METHOD FOR EVALUATING FRACTURES OF A WELLBORE
(FR) PROCÉDÉ POUR L'ÉVALUATION DE FRACTURES D'UN PUITS DE FORAGE
Abstract:
(EN) The present invention relates to a method for evaluating fractures of a wellbore, wherein the method comprises: - installing (201) at least one temperature sensor in a zone of the wellbore; - monitoring (203) a temperature for a plurality of time thanks to at least one temperature sensor; - modifying (202) on purpose a pressure in the wellbore; - determining a quality indicator (208, 207) based on at least: - a direction of a variation of the monitored temperature after the modification of the pressure (205); - a comparison of the monitored temperature after the modification of the pressure with at least two reference curves (206).
(FR) La présente invention se rapporte à un procédé pour l'évaluation de fractures d'un puits de forage, le procédé comprenant : l'installation (201) d'au moins un capteur de température dans une zone du puits de forage ; le suivi (203) d'une température pour une pluralité de moments grâce à au moins un capteur de température ; la modification (202) délibérée d'une pression dans le puits de forage ; et la détermination d'un indicateur de qualité (208, 207) sur la base d'un sens de variation de la température suivie après la modification de la pression (205) et/ou d'une comparaison de la température suivie après la modification de la pression avec au moins deux courbes de référence (206).
