Title (EN) DELAYED POLYMER GELATION USING LOW TOTAL DISSOLVED SOLIDS BRINE
(FR) GÉLIFICATION DE POLYMÈRE RETARDÉE À L'AIDE D'UNE SAUMURE À FAIBLE TENEUR EN SOLIDES DISSOUS TOTAUX
Abstract:
(EN) A method for placing a gel deep inside a subterranean formation includes combining a crosslinkable polymer, a chromium (III) crosslinking agent, and a brine to form a gelation solution. The gelation solution is pumped within a subterranean wellbore. The gelation time of the gelation solution is elongated by reducing the total dissolved solids of the brine so that the gelation solution penetrates deep into the subterranean formation away from the wellbore before a gel is formed.
(FR) Cette invention concerne un procédé pour placer profondément un gel dans une formation souterraine, le gel comprenant la combinaison d'un polymère réticulable, d'un agent de réticulation de type chrome (III) et d'une saumure pour former une solution de gélification. La solution de gélification est pompée dans un puits de forage souterrain. Le temps de gélification de la solution de gélification est prolongé par réduction des solides dissous totaux de la saumure de façon que la solution de gélification pénètre profondément dans la formation souterraine à l'opposé du puits de forage avant formation du gel.
