Abstract: In accordance with the teachings of the present invention, a system and method for forming an annular isolator between production tubing and a borehole wall is provided. A section of expandable tubing is installed in a borehole, and a sleeve disposed around a surface of the tubing cooperates with the tubing to form a fluid chamber. The sleeve includes a first portion that is predisposed to expand outwardly under fluid pressure from the fluid chamber, and a second portion that is configured such that, when expanded due to fluid pressure, the second portion stores energy that is biased to sustain the fluid pressure within the chamber, in response to a change in fluid volume. The tubing may be expanded using a tool disposed within the tubing.

Abstract: Containers are provided. An exemplary container for storing an item comprises: an insulating material; a pressure-maintaining container defining an interior, the pressure-maintaining container being surrounded by the insulating material; and a temperature-maintaining material disposed within the interior of the pressure-maintaining container, the temperature-maintaining material being arranged to maintain a temperature of an item placed with the container. The temperature-maintaining material sublimates during warming to produce sublimation gasses and the pressure-maintaining material is operative to control venting of the sublimation gasses such that pressure higher than atmospheric pressure is maintained about the temperature-maintaining material. Methods also are provided.

Abstract: 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.

Abstract: The present inventions relate to improved apparatus and methods for radially expanding tubulars, such as tubing, casing and sand-control screen assemblies in a subterranean oil or gas well, and more specifically, to a variable diameter expansion tool for expanding downhole tubulars to varying diameters. In general, the inventions provide apparatus and methods for radially expanding a tubular, such as pipe, tubing, screen or screen assembly, deployed in a subterranean well by moving an expansion tool axially through the well. An automatically infinitely variable-diameter expansion cone tool is provided. A variable-diameter cone is provided, movable between an expanded position and a retracted position. The cone is enlarged to its expanded position and advanced through expandable components until a restriction is reached. At the restriction, the variable-diameter cone automatically retracts enough to allow the tool to continue advancing through the wellbore.

Abstract: A multi-layer deformable composite construction. In a described embodiment, a method of expanding a structure in a wellbore includes the steps of: positioning the structure in an unexpanded configuration in the wellbore, the structure including a wall made up of multiple layers; expanding the structure to an expanded configuration while permitting relative displacement between the layers; and then preventing relative displacement between the layers.

Abstract: A ported expandable tubing having an outer valve sleeve which closes the ports upon tubing expansion. An elastomeric sealing member may be carried between the tubing and the valve sleeve to improve closing of the ports. The elastomeric sealing member may be shaped and positioned to operate as a check valve before tubing expansion. Various fluids may be flowed from the ported tubing into a borehole, or from the borehole into the ported tubing, before tubing expansion. After expansion, the ports are closed by residual clamping forces between the sleeve and tubing. By applying sufficient internal pressure to overcome the clamping forces, fluids can be flowed from the tubing into the borehole after expansion.
