Title (EN) METHOD OF USING LOW-DENSITY, FREEZABLE FLUID TO CREATE A FLOW BARRIER IN A WELL
(FR) PROCÉDÉ D'UTILISATION D'UN FLUIDE CONGELABLE À FAIBLE DENSITÉ POUR CRÉER UNE BARRIÈRE D'ÉCOULEMENT DANS UN PUITS
Abstract:
(EN) Disclosed herein is a temporary wellbore sealant, comprising water, a gelling agent; and a filler, wherein: the filler has a lower specific gravity than the water of the sealant; and the sealant has a lower specific heat than the water of the sealant and a method of temporarily sealing a liquid filled wellbore therewith.
(FR) L'invention concerne un produit d'étanchéité temporaire de puits de forage, comprenant de l'eau, un agent gélifiant, et une charge. La charge a une densité spécifique inférieure à celle de l'eau du produit d'étanchéité, et le produit d'étanchéité a une chaleur spécifique inférieure à celle de l'eau du produit d'étanchéité. L'invention concerne également un procédé d'étanchéification temporaire d'un puits de forage rempli de liquide à l'aide du produit d'étanchéité.
