Abstract

In order to gain strength and durability a typical packer that is mechanically compressed when set will be reinforced with shape memory alloy (“SMA”). The SMA would work as support and when target temperatures are reached the SMA would begin to deploy allowing the packer to set and would provide reinforcement stress to the wellbore. This would make a more reliable, durable pressure seal. The SMA would be made in the shape resembling a set packer. The SMA would be made into rods that would be mechanically straightened. Once straightened the elastomer would be molded around a pattern of SMA rods. The rods would be weaved together, forming a strong support structure for the packing element. The packer would be placed on an outside diameter of a tool. Once the target bottom hole temperature is reached and the packer is being set, the SMA would begin to deploy and increase the sealing force of the packer. The SMA could be made into rings or chopped up when added to the packing element.
