Abstract
A straddle packer assembly for deployment in a wellbore in which the straddle packer assembly includes a mandrel on which is mounted a first inflatable element and a second inflatable element. A first end of the first inflatable element is fixed, while a second end slides on the mandrel. Both the first and second ends of the second inflatable element are slidable on the mandrel, and the first end of the second inflatable element is coupled to the second end of the first inflatable element. The inflatable elements are inflated separately, with the first inflatable element inflated first until it seats against the wellbore wall. As the first inflatable element expands radially and contracts axially, the second inflatable element moves in axial concert with the first inflatable element so as to maintain a fixed distance between the two inflatable elements.
