A device for monitoring an formation below the ground G containing a fluid such as COor methane comprising a measuring cell arranged in a cavity, can an F analyzer disposed on the surface and a sealed connection connecting measuring cell to the analyzer. The measuring cell comprises two chambers that can sealingly communicate with one another. The first chamber comprises a plurality of orifices allowing passage of the fluid into first chamber, at least two inner electrodes and fluid circulator. The second chamber is impervious to the fluid. Applications include monitoring of geological storages sites for gas such as CO.

Permanent soil and subsoil measurement probe

The invention relates to a fluid sampling device comprising a sample chamber () including a lower piston (), an upper piston () and an intermediate piston (). Intermediate piston () is moved so as to guarantee a substantially constant volume for chamber () when closing the chamber.

Device for sampling fluid under pressure for geological site development monitoring

The invention is a device for sampling fluids under pressure from a well which comprises a chamber for retaining the fluid within a sample chamber (). The chambers includes a first piston which allows or prevents fluid inflow into the lower part of the chamber. The first piston is displaced by means comprising an elastic element () disposed in a chamber filled with oil and connected to the piston by a rod (). Sampled fluid transfer means allows control of the descent of a second piston () from the upper part to the lower part of the chamber so that the fluid remains at constant pressure in chamber during the transfer.
