Title
(EN) WELLHEAD GROWTH MONITORING SYSTEM
(FR) SYSTÈME DE SURVEILLANCE DE CROISSANCE DE TETE DE PUITS
Abstract
(EN) Systems and methods include a computer-implemented method: Real-time measurements are received by a wellhead growth monitoring computer system from a sensor on a wellhead of a well. The sensor is directed to a fixed point on a platform grating that is facing or underneath the wellhead. The real-time measurements, including measurements of a distance from the sensor to the fixed point, are analyzed by the wellhead growth monitoring computer system, including comparing the real-time measurements to previously-received measurements from the sensor. A determination is made, by the wellhead growth monitoring computer system based on the analyzing, that wellhead growth of a wellhead structure of the well has occurred. The wellhead growth is a vertical elongation of the wellhead structure. A notification that is provided to a user includes a measure of the wellhead growth and a time at which the wellhead growth occurred.
(FR) La présente invention concerne des systèmes et des procédés qui comprennent un procédé mis en œuvre par ordinateur. Des mesures en temps réel sont reçues par un système informatique de surveillance de croissance de tête de puits en provenance d'un capteur sur une tête de puits d'un puits. Le capteur est dirigé vers un point fixe sur un réseau de plate-forme qui est en regard, ou en dessous, de la tête de puits. Les mesures en temps réel, comprenant des mesures d'une distance du capteur au point fixe, sont analysées par le système informatique de surveillance de croissance de tête de puits, comprenant la comparaison des mesures en temps réel à des mesures précédemment reçues du capteur. Une détermination est faite, par le système informatique de surveillance de croissance de tête de puits sur la base de l'analyse, que la croissance de tête de puits d'une structure de tête de puits du puits s'est produite. La croissance de tête de puits est un allongement vertical de la structure de tête de puits. Une notification qui est fournie à un utilisateur, comprend une mesure de la croissance de la tête de puits et un moment auquel la croissance de tête de puits s'est produite.
