Abstract
According to the invention, a method for isolating a zone inside a well is provided. The method may include providing a catch screen at a first location in the well and providing a fluid flow to the catch screen. The fluid flow may include a first fluid and a shape memory material. The first fluid may at least partially pass through the catch screen. The shape memory material may accumulate at the catch screen. The method may also include triggering the shape memory material such that it changes from a first shape to a second shape, thereby at least partially isolating one portion of the well from another portion of the well.
