摘要:
The present invention relates to the use of amphiphilic sequenced copolymers as an agent for controlling the filtrate in a fluid (F) injected under pressure into an underground formation, comprising—at least one chain (C) soluble in the fluid (F); and—at least one block (B) that is insoluble in the fluid (F).
