Title (EN) METHOD FOR BLOCKING A STORAGE WELL
(FR) MÉTHODE D'OBTURATION DES PUITS DE STOCKAGE
Abstract:
(EN) The invention relates to a method for blocking a well drilled in a reservoir rock subjacent to a rock layer, in particular an argillaceous one, forming a cover. The method comprises the following steps: identifying the cover level in the well; filling the well with particles of an argillaceous material (13) above the cover level; and compacting the particles so as to reform the layer defining the cover.
(FR) La présente invention concerne une méthode d'obturation d'un puits foré dans une roche réservoir sous-jacente à une couche de roche, notamment argileuse, constitutive d'une couverture. Selon la méthode, on effectue les étapes suivantes : - on identifie dans le puits le niveau de la couverture, - on remplit le puits de particules de matériaux argileux (13) au droit du niveau de la couverture, - on compacte les particules de façon à reconstituer la couche constitutive de la couverture.
