Abstract

A field assembled packer or plug features a sleeve of a swelling material, preferably rubber, which is slipped over the tubular. A pair of molds is assembled over the tubular. The molds can accommodate variation in the size and out of roundness of standard API tubulars. An epoxy mixture is formulated on site and pumped into the molds at opposed ends of the sealing element assembly and allowed to set up. The molds are removed and the assembly is ready to be run in the hole as a packer included in a tubular string. The element assembly can include a harder swelling material on opposed ends of the main sealing element to protect the main sealing element from damage during run in.
