Abstract
A packer having a thermal memory spacing system that includes a portion of the system that that selectively changes an outer diameter due. The packer may include upper and lower sealing elements, and at least one thermal memory shape material sub positioned between the sealing elements. The thermal memory shape material sub may have a first outer diameter at a first temperature and a second larger outer diameter at a second temperature. The first temperature may be greater than the second temperature. The outer diameter of the sub may be selectively increased to temporarily decrease the annular area in which debris and/or materials may collect and potentially cause the packer to become stuck within the wellbore. Prior to moving the packer to a different location, the outer diameter of the sub may be decreased to increase the annular area.
