Patent abstract
In an example, a method of repairing a pipeline includes isolating a section of a pipeline that includes a leak site. The method includes flooding the section of the pipeline with a plug formulation that includes artificial platelets and an ultraviolet (UV) photoinitiator. The section may be pressurized to induce migration of the artificial platelets to the leak site. The method also includes draining excess plug formulation from the section of the pipeline. The method further includes exposing the UV photoinitiator to UV light to form a gas impermeable seal at the leak site.
