Title (EN) MANAGED PRESSURE AND/OR TEMPERATURE DRILLING SYSTEM AND METHOD
(FR) SYSTEME ET PROCEDE DE FORAGE A PRESSION ET/OU TEMPERATURE GEREE
Abstract: front page image
(EN)The present invention relates to a managed pressure and/or temperature drilling system (300) and method. In one embodiment, a method for drilling a wellbore into a gas hydrates formation is disclosed. The method includes drilling the wellbore into the gas hydrates formation; returning gas hydrates cuttings to a surface of the wellbore and/or a drilling rig while controlling a temperature and/or a pressure of the cuttings to prevent or control disassociation of the hydrates cuttings.
(FR)La présente invention concerne un système et un procédé de forage à pression et/ou température gérée. Dans un mode de réalisation, un procédé de forage de puits dans une formation d'hydrate de gaz est exposé. Le procédé implique de percer le puits dans la formation d'hydrates de gaz, de rapporter les déblais d'hydrates de gaz à une surface du puits et/ou à une installation de forage tout en contrôlant la température et/ou la pression des déblais pour empêcher ou contrôler la dissociation des déblais d'hydrates.
