Abstract
The present invention relates to the use of a sequenced polymer as an agent for monitoring the filtrate and the rheology of a fluid injected under pressure into an oil rock, wherein the fluid comprises solid particles and/or is brought into contact with solid particles within the oil rock after being injected, the polymer comprising: a first block which is adsorbed onto at least some of the particles; and a second block having a composition other than that of the first block and a mean molecular weight of more than 10,000 g/mol, for example more than 100,000 g/mol, and which is soluble in the fluid.
