Abstract:
1. A method for sealing an annular space between a well tubular and the surrounding formation or between pipes of a wellbore, said method comprising the steps of a) loading one or more treatment fluids separately into one or more fluid containers arranged in an injecting tool body that surrounds the one or more fluid containers, each of the one or more fluid container comprising container walls surrounding the one or more treatment fluids in the fluid container, wherein an interior space of the one or more fluid containers is in fluid communication with the annular space via one or more respective outlet openings of the one or more containers, b) lowering the injecting tool body into the wellbore or the well tubular to a predetermined position, c) exposing at least part of an outside of the container walls to a surrounding pressure in the wellbore via openings in the injecting tool body, d) allowing at least part of each of the one or more fluid containers walls to displace within the tool body under forces exerted on the container walls by the surrounding pressure in the wellbore, e) pumping the one or more treatment fluids from each of the one or more fluid container into the wellbore or the well tubular via the one or more respective outlet openings of the one or more containers.
