Abstract: Apparatus and methods for measuring confining pressure, axial strain and radial strain of zonal isolation materials are described. This information is useful for evaluating these materials and predicting seal performance and potential failures of these materials.

Abstract: The isolation of selected regions downhole may be achieved using methods that include emplacing a polymerizable material within a wellbore, wherein the polymerizable material contains a polymerizable component and a latent curing agent; initiating polymerization of the polymerizable material; and forming a seal within the wellbore. Permanent or semi-permanent downhole seals may also be prepared using methods that include emplacing a section of pipe having a surrounding membrane into an interval of a wellbore, wherein the surrounding membrane contains a polymerizable material, and deploying the membrane downhole to form a seal.
