Abstract: front page image
(EN)The invention provides a method made of steps of providing a composition comprising a first chemical component and a degradable protective layer, wherein the degradable protective layer is at least partially degradable when subject to temperature, pH or time; and introducing into a wellbore the composition and allowing the degradable protective layer to degrade and release the first chemical component.
(FR)Cette invention concerne un procédé comprenant les étapes consistant à préparer une composition contenant un premier composant chimique et une couche de protection dégradable, ladite couche de protection dégradable étant au moins partiellement dégradable quand elle est soumise à une certaine température, un certain pH ou dans le temps ; et à introduire la composition dans un puits de forage et à laisser la couche de protection dégradable se dégrader et libérer le premier composant chimique.
