A method for sealing and/or consolidating a subterranean formation, the subterranean formation being traversed by at least one injection well, includes the steps of preparing a gelling aqueous solution comprising an alkaline solution of potassium silicate, acetic acid and an aluminate, and injecting from the injection well, into the subterranean formation, the gelling aqueous solution to seal and/or to consolidate the subterranean formation.

Method for treating a subterranean formation by injecting an aqueous gelling solution comprising an aluminate

The invention relates to a system and to a method for separating into at least one of liquid and gas phase compounds contained in a sample. The system comprises: an oven (D1) for heating in an inert atmosphere according to a sequence of temperatures, a first experimental setup (M1) connected to oven (D1) when it is in operation, comprising circulating the effluent resulting from heating in an inert atmosphere towards collection of (U) this effluent, a second experimental setup (M2) connected to first experimental setup (M1) when the oven is no longer in operation, comprising vacuum circulation (PI, P.G., TP) of the effluent collected by the first setup towards (T1, T2) which separate the collected effluent into at least one of liquid and gas phases.

System and method for determining the chemical composition of compounds contained in a sample

The present invention relates to a process for the treatment of the area () surrounding a well () in which an aqueous gelling solution comprising an alkaline potassium silicate solution and an acetic acid is prepared and then injected into a subterranean formation. This aqueous gelling solution makes it possible, by virtue of these gelling properties, to block the area () surrounding the well ().
