CA 2250563

Improved methods of completing unconsolidated subterranean zones penetrated by wellbores are provided. The methods basically comprise the steps of placing a slotted liner in the zone, isolating the slotted liner and the wellbore in the zone, injecting a hardenable resin composition coated particulate material into the zone by way of the slotted liner and then causing the hardenable resin composition to harden whereby the particulate material is consolidated into a hard permeable uniform mass.

Méthodes améliorées de complétion de puits forés dans des zones souterraines de roche meuble. Les méthodes comprennent fondamentalement les étapes suivantes : placer une colonne perdue perforée dans la zone, isoler la colonne perdue perforée et le puits foré dans la zone, à partir de la colonne perdue perforée injecter dans la zone un matériau particulaire enduit d'une composition de résine durcissable; faire durcir cette composition afin que le matériau particulaire puisse se consolider et former une masse uniforme, dure et perméable.
