Filed:

Jun 4, 2002

Appl. No.:

10/162437

Inventors:

Steven R. Fipke - Sherwood Park, CA
Ernest C. Bailey - Lake Dallas TX
David J. Steele - Irving TX
Travis W. Cavender - Angleton TX

Assignee:

Halliburton Energy Services, Inc. - Dallas TX

International Classification:

E21B 4312

US Classification:

166381, 166 50, 166386

Abstract:

Specially designed apparatus is utilized to provide convenient isolation of a wellbore junction from pressure and corrosion during an acid fracturing stimulation process performed in a main or branch wellbore portion downhole from the junction. The apparatus has an outer tubular portion which may be installed, in a single trip into the main wellbore, in a straddling and sealing relationship with the junction, and an inner tubular structure sealingly and removably received within the outer tubular structure. Fracturing acid may be pumped directly down the main wellbore, and then to the formation to be stimulated, via the interior of the outer tubular structure, after the removal of the inner tubular structure subsequent to its use in facilitating a downhole pressure test of a lower end seal portion of the outer tubular structure.

E21B023/00

US Classification:

166313, 166 50, 1661176, 166207

Abstract:

An expanding wellbore junction system, apparatus and methods are provided for forming a sealed wellbore intersection in a subterranean well. In one described method, an expandable wellbore junction is expanded within an under-reamed cavity in a wellbore. Intersecting tubular legs of the wellbore junction are then drifted using a drifting apparatus. A deflection device may be used to direct a drift of the drifting apparatus into a selected one of the wellbore junction legs.

US Classification:

166313000, 166117500

Abstract:

An anchor for a branch wellbore liner. In a described embodiment, a system is used to anchor between an upper portion of a window formed through a sidewall of a first tubular string and an upper end of a second tubular string extending outwardly from the window. The system includes a first anchoring device at the upper portion of the window, and a second anchoring device at the upper end of the second tubular string. The first and second anchoring devices are operative to secure the upper end of the second tubular string to the upper portion of the window.
