Abstract: A logging probe supporting device includes a connector that can be plugged in at the bottom of the well with a logging cable contained in the inner space of rods to which the supporting device is fastened and fluid communicating openings provided between the inner space of the rods and the outside of the supporting device, the openings being arranged between the probe and connector. The device includes, between the openings and the connector, a shutoff such as check valves allowing fluid circulation from the inside towards the outside and preventing circulation from the outside towards the inside of the supporting device.

Abstract: Method of treating the area surrounding an acid gas storage well (1) using a reactive solution, wherein the following stages are carried out: a) injecting from the well a wash fluid for washing the rock of said surrounding area so that it no longer contains products reactive with said solution, b) injecting into the rock thus washed a predetermined volume of reactive solution suited to react with acid gases.

Abstract: The invention relates to a logging probe (2) supporting device (3) comprising connecting means (4) that can be plugged in at the bottom of the well with a logging cable contained in the inner space of rods (7) to which the supporting device is fastened, fluid communication means between the inner space of the rods and the outside of the supporting device, the communication means being arranged between the probe and the connecting means. The device comprises, between the communication means and the connecting means, shutoff means such as check valves allowing fluid circulation from the inside towards the outside and preventing circulation from the outside towards the inside of the supporting device.
