DOWNHOLE SCALE REMEDIATION ABOVE A DOWNHOLE SAFETY VALVE
Scale remediation at or around a downhole safety valve (DSV), including the volume of a wellbore in a subterranean formation above the DSV. Wellbore fluid is displaced using a gas, the DSV is closed, the gas is released, and a treatment fluid comprises a base fluid and a scale-removal agent is allow...

| description | Scale remediation at or around a downhole safety valve (DSV), including the volume of a wellbore in a subterranean formation above the DSV. Wellbore fluid is displaced using a gas, the DSV is closed, the gas is released, and a treatment fluid comprises a base fluid and a scale-removal agent is allowed to react with scale in the volume of the wellbore above the DSV.
L'invention concerne le détartrage au niveau ou autour d'une soupape de sécurité de fond de trou (DSV), incluant le volume d'un puits de forage dans une formation souterraine au-dessus de la DSV. Le fluide de forage est déplacé en utilisant un gaz, la DSV est fermée, le gaz est libéré, et un fluide de traitement comprenant un fluide de base et un agent d'élimination de tartre est amené à réagir avec le tartre dans le volume du puits de forage au-dessus de la DSV. |
