Abstract:
A lateral packer and felt combination are disclosed for use in efficiently inhibiting infiltration into or out of a pipeline. The lateral packer is inflated and expands radially to secure the felt at the source of infiltration. Once the felt is secured, the lateral packer is removed and the felt left in place as a barrier to infiltration.
