High Expansion Gauge Hanger.

The GH is a high expansion device for hanging off gauges and other tools in the well. Designed for use in tubing with no nipple profiles, the GH provides a platform to hang gauges from while at the same time constituting a negligible flow restriction. The tool can also be used as an anchor to prevent unwanted movement of, for example, abandoned equipment in flowing wells.

Two bi-directional slip modules allow loads in either direction and self centralise the tool on setting. On retrieval the slips are positively retracted from the tubing/casing wall to their running position. The GH can be run on slickline or electric cable and is set using standard setting tools. Retrieval is with a JDC pulling tool for simplicity.

The GH tool comes in three versions: The GH150 with a run OD of 1.5”, GH200 with a run OD of 2.0”, and the GH288 with an OD of 2 7/8”. Adapter kits enable one size of GH to set in the range of tubing’s from 2 7/8” through to 9 5/8” - which drastically reduces inventory costs.
