    摘要： The present disclosure addressed apparatus and methods for forming an annular isolator in a borehole after installation of production tubing. Annular seal means are carried in or on production tubing as it is run into a borehole. In conjunction with expansion of the tubing, the seal is deployed to form an annular isolator. An inflatable element carried on the tubing may be inflated with a fluid carried in the tubing and forced into the inflatable element during expansion of the tubing. Reactive chemicals may be carried in the tubing and injected into the annulus to react with each other and ambient fluids to increase in volume and harden into an annular seal. An elastomeric sleeve, ring or band carried on the tubing may be expanded into contact with a borehole wall and may have its radial dimension increased in conjunction with tubing expansion to form an annular isolator.

    摘要： Methods relating to the hydrolysis of water-hydrolysable materials are provided. In one embodiment, a method of treating at least a portion of a subterranean formation is provided, the method comprising: providing a water-hydrolysable material; introducing the water-hydrolysable material into a well bore penetrating the subterranean formation; providing a treatment fluid comprising an aqueous liquid and a water-miscible solvent; introducing the treatment fluid into the well bore so as to contact the water-hydrolysable material; and allowing the water-hydrolysable material to hydrolyze. Methods of completing a well also are provided.
