Title (EN) A METHOD OF ABANDONING A WELL
(FR) PROCÉDÉ D’ABANDON D’UN PUITS
Abstract:
(EN) A method of a bandoning a well in a reservoir. The method including the step of forming a scale in the reservoir by introducing into the reservoir a first solution comprising a first scale precursor and a second solution comprising a second scale precursor and a scale inhibitor. The first solution and second solution are able to react together to form the scale. The method further includes the step of at least partially filling the well with cement.
(FR) La présente invention concerne l’abandon d’un puits dans un réservoir. Le procédé comprend l’étape de formation de tartre dans le réservoir en introduisant dans le réservoir une première solution comprenant un premier précurseur de tartre et d’une seconde solution comprenant un second précurseur de tartre et un inhibiteur de tartre. La première solution et la seconde solution peuvent réagir ensemble pour former le tartre. Le procédé inclut en outre l’étape de remplissage au moins partiellement du puits avec du ciment.
