Title
(EN) WELL MONITORING SYSTEM FOR MONITORING A SUBSEA, SUB-SURFACE WELL
(FR) SYSTÈME DE SURVEILLANCE DE PUITS POUR SURVEILLER UN PUITS EN SOUS-SOL, SOUS-MARIN
Abstract
(EN) Embodiments herein describe apparatus, systems and methods adapted to monitor underwater wells, boreholes, drill holes, etc. (subsea wells). Depending on embodiment, the apparatus, systems and methods can be configured to capture sensor readings and/ or to monitor status of a target subsea wells. A system with a well sensor device (405) comprising a funnel (410) configured to be positioned over a subsea well in order to capture a material of interest leaking from the subsea well, and a sensor (415) disposed at a top of the funnel and configured to detect the material of interest; and a well monitoring device (120) configured to be positioned in a water column, wherein the well monitoring device (120) is communicatively coupled to the well sensor device (405) to retrieve sensor readings from the sensor (415) on the well sensor device, and a cable configured to connect the well monitor device to a sensor reading port of the well sensor device.
(FR) Des modes de réalisation de l'invention concernent un appareil, des systèmes et des procédés conçus pour surveiller des puits et des trous de forage sous-marins, etc. Selon un mode de réalisation, l'appareil, les systèmes et les procédés peuvent être conçus pour capturer des relevés de capteur et/ou pour surveiller l'état d'un puits sous-marin cible.
