Title (EN) METHOD FOR COUNTERACTING LAND SUBSIDENCE IN THE VICINITY OF AN UNDERGROUND RESERVOIR
(FR) PROCÉDÉ PERMETTANT DE CONTRECARRER UN AFFAISSEMENT DE TERRAIN AU VOISINAGE D'UN RÉSERVOIR SOUTERRAIN
Abstract:
(EN) The invention relates to a method for counteracting land subsidence due to activities, such as production of resources, involving transport of materials to or from an underground reservoir (R) through a well (P) having a well bore (B) running in the direction of the reservoir. The method comprises the step of bringing reinforcing material into a casing present in the wellbore(B) and making the reinforcing material flow out through perforations in the casing for forming a number of reinforcing objects (D) of reinforcing material around the wellbore (D).
(FR) L'invention se rapporte à un procédé permettant de contrecarrer un affaissement de terrain dû à des activités, telles que la production de ressources, impliquant le transport de matériaux jusqu'à un réservoir souterrain (R), ou à partir de ce dernier, à travers un puits (P) ayant un puits de forage (B) et s'étendant en direction du réservoir. Le procédé comprend l'étape consistant à mettre un matériau de renforcement dans un tubage présent dans le puits de forage (B) et à réaliser l'écoulement du matériau de renforcement à travers des perforations dans le tubage pour former un certain nombre d'objets de renforcement (D) d'un matériau de renforcement autour du puits de forage (D).
