Abstract
A method of inhibiting leakage of a fluid through a defect (4) in a wall of a pipe (2), comprising the steps: introducing a loss control medium (30) into a first portion of a pipe (2); conveying the loss control medium (30) along the pipe from the first portion to a second portion of the pipe, wherein the second portion is embedded in a porous medium and has a defect (4) through which fluid conveyed by the pipe during normal use leaks into the porous medium; and applying a pressure to the loss control medium (30) such that at least a portion of the loss control medium (30) is expelled from the pipe through the defect (4) into the porous medium thereby causing the loss control medium to accumulate within the porous medium in the vicinity of the defect which inhibits flow of a liquid through the defect into the porous medium.
