<p>To remove particulate debris from a pipeline, a plug train including at least one debris entraining gel plug and at least one pseudoplastic plug is passed through a pipeline by means of a driving fluid and the debris is collected by the debris entraining gel plug. The pseudoplastic plug is used, optionally in combination with one or more separators, to separate the debris entraining gel plug from the fluids inthe pipeline.</p> |
