Abstract
A retrievable pig for cleaning blockage material from a pipeline, comprising a string of tubing within the pipeline from a proximate location at the entrance to the pipeline to a distal location within the pipeline, a pig assembly comprising a flexible cup which will collect pipeline blockage material, a seal which engages the internal bore of the pipeline being cleaned, and a connection to the distal end of the string of tubing; pushing the pig assembly with fluid in the annular area between the internal bore of the pipeline and the outer diameter of the string of tubing until the pig assembly engages the blockage material, and pumping a flow of fluid thru the internal string of tubing to a location beyond a portion of the blockage material, the flow of fluid urging the pig assembly and the portion of the blockage material towards the proximate location.
