METHOD OF USING DELAYED HYDRATABLE POLYMERIC VISCOSIFYING AGENT IN THE TREATMENT OF A WELL OR SUBTERRANEAN FORMATION

The disclosure relates to a method of delaying viscosification of a well treatment fluid within a well or within a subterranean formation penetrated by a well by introducing into the well a hydratable viscosifying agent of particulates having a minimum of 40% retention on a 60 mesh screen and a mini...

Zusammenfassung:	The disclosure relates to a method of delaying viscosification of a well treatment fluid within a well or within a subterranean formation penetrated by a well by introducing into the well a hydratable viscosifying agent of particulates having a minimum of 40% retention on a 60 mesh screen and a minimum of 1% retention on a 20 mesh screen. Cette divulgation concerne un procédé permettant de retarder la viscosification d'un fluide de traitement de puits à l'intérieur d'un puits ou d'une formation souterraine comportant un puits par introduction dans le puits d'un agent viscosifiant hydratable sous forme particulaire caractérisé par une rétention minimale de 40 % sur un crible de 60 mesh et par une rétention minimale de 1 % sur un crible de 20 mesh.
