This experimental study evaluated the performance of PBR seal assemblies for thermal well service in situations where isolation of the tubing/casing annulus is required. A series of bench scale tests were completed with a purpose-built test fixture to screen a number of different materials for use as packing elements in thermal wells. The tests quantified the seal characteristics of the materials and, coupled with additional evaluations of various tool designs, the project provided a good understanding of the key factors controlling the successful performance of these assemblies.
