Abstract
A downhole sealing tool may include a sealing element disposed on a mandrel for lowering into a well. The sealing element may be captured at the ends between the mandrel and a shroud and may span a gland opening between upper and lower shroud portions. Props between the mandrel and the shroud are axially moveable to engage the sealing element and urge the sealing element radially outwardly into a controlled volume defined at the gland opening between the mandrel and a portion of the well to be sealed. A higher squeeze ratio is achievable, allowing for a thinner element and tool profile with greater flowability.
