Abstract (en)
[origin: WO2017131520A1] The invention relates to a method for counteracting land subsidence due to activities, such as production of resources, involving transport of materials to or from an underground reservoir (R) through a well (P) having a well bore (B) running in the direction of the reservoir. The method comprises the step of bringing reinforcing material into a casing present in the wellbore(B) and making the reinforcing material flow out through perforations in the casing for forming a number of reinforcing objects (D) of reinforcing material around the wellbore (D).
