Abstract
In a method of sealing a fracture () in a formation () surrounding a wellbore provided with a non-cemented perforated liner (), a placement tool () is introduced into the liner, and a first and second annular flow barrier () create an upstream (), an intermediate () and a downstream section (). A cross flow shunt tube () connects the upstream section and the downstream section, and a sealing fluid outlet () is arranged in the intermediate section. A placement fluid is caused to flow into the fracture and controlled to obtain a desired fluid flow in an annular space between the liner and the formation that is directed in downstream direction at a position upstream the fracture and in the upstream direction at a position downstream the fracture. When said desired flow is obtained, sealing fluid is ejected from the sealing fluid outlet. A sealing system is furthermore disclosed.
