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.

Annular isolators for expandable tubulars in wellbores

Provided are a manufacturing method of a semiconductor device and a substrate processing apparatus. The manufacturing method of the semiconductor device includes: loading a plurality of substrates into a reaction vessel, which is configured by a process tube and a manifold that supports the process tube, and arranging the loaded substrates within the reaction vessel; pre-processing the plurality of substrates by supplying a pre-process gas from the manifold side toward the process tube side within the reaction vessel; main-processing the plurality of pre-processed substrates by supplying a main-process gas from the manifold side toward the process tube side within the reaction vessel; and unloading the plurality of main-processed substrates from the reaction vessel, wherein in pre-processing the plurality of substrates, the pre-process gas is supplied from at least one position in an area corresponding to the manifold, and at least one position in an upper area of an area corresponding to a substrate arrangement area.

Manufacturing method of semiconductor device and substrate processing apparatus

A method of interconnecting first and second wellbores. The method comprises the steps of: forming a radially enlarged cavity (20) in the first wellbore (12) below casing (14) lining the first wellbore (20); positioning a wellbore connector (22) within the cavity (20), the wellbore connector (22) being configurable in expanded and contracted configurations; and expanding the wellbore connector (22) within the cavity (20).

The invention is a sealing system, such as a packer, that is used in a wellbore to seal against an exterior surface, such as a casing or open wellbore. The sealing system includes a swellable material that swells from an unexpanded state to an expanded state thereby creating a seal when the swellable material comes into contact with a triggering fluid.

System and method to seal using a swellable material

An intelligent well system and method has a sand face completion and a monitoring system to monitor application of a well operation. Various equipment and services may be used. In another aspect, the invention provides a monitoring system for determining placement of a well treatment. Yet another aspect of the invention is an instrumented sand screen. Another aspect is a connector for routing control lines.

Intelligent well system and method

One or more subterranean zones are isolated from one or more other subterranean zones using a combination of solid tubulars and perforated tubulars.

Isolation of subterranean zones

An expansion mandrel includes a lubrication system for lubricating the trailing edge portion of the interface between the expansion mandrel and a tubular member during the radial expansion of the tubular member.

Lubrication and self-cleaning system for expansion mandrel

An apparatus and method for repairing a wellbore casing (100). An opening (115) in a wellbore casing (100) is located using a logging tool (310). An expandable tubular member (370) is then positioned in opposition to the opening (115) in the wellbore casing (100). The expandable tubular member (370) is then radially expanded into intimate contact with the wellbore casing (100).

Wellbore casing repair

An apparatus for radially expanding atubular member that includes a support member having an exterior surface, a tubular member having an interior surface coupled to the support member, an annular expansion cone having a continuous outer surface movably coupled to the exterior surface of the support member and the interior surface of the tubular member for radially expanding the tubular member, and a preload assembly coupled to the support member for applying an axial force from the support member to the annular expansion cone to preload the annular expansion cone against the tubular member. The preload assembly including a compressed spring coupled to the support member for applying the axial force to the annular expansion cone.
