Abstract
A borehole barrier comprises a scroll where the overlapping parts have a ratchet for radial expansion against a surrounding tubular with the ratchet controlling springing back. The outer surface can have carbide or other hard particles to penetrate the surrounding tubular for fixation. The end of the scroll forms a tapered ball seat. Expansion into place can be with a tool, or by releasing potential energy in the scroll or by using a shape memory alloy that enlarges at above its critical temperature. The scrolls can be removed by milling or allowed to dissolve or disintegrate with exposure to well fluids. The scroll design is quickly deployed and removed and is far more economical than known plugs that have the traditional seal and slip design. The balls can be milled out with their associated scrolls or flowed to the surface with produced fluids.
