Claim 0:
1. A system for curing at least one leakage site in a pipeline, the system comprising:
a) at least one gel pig; and
b) at least one fibers-in-sealant-in carrier fluid (FISIC) composition, adapted to provide a caulking mechanism, wherein said fibers in at least one form selected from the group consisting of: wound fibers, yarns and combinations thereof; and wherein said at least one gel pig and said at least one -in-carrier fluid FISIC composition form a pig train, adapted to move along said pipeline to a region of said at least one leakage and to seal and cure said at least one leakage, wherein said FISIC composition comprises 0.5-5% composition A, 1-7% composition B, 0.5-5% fibers, 1-6% silica and 85-98% carrier fluid, and wherein said fibers are hydrophilic and are adapted to trap said sealant in said FISIC within a three-dimensional structure of at least one of said wound fibers and said yarns and wherein said fibers are adapted to be expanded in said FISIC, thereby curing said pipeline at said at least one leakage site.
