Appl. No.:

10/441521

Inventors:

Michael A. Carmody - Houston TX, US
Robert S. O'Brien - Katy TX, US

Assignee:

Baker-Hughes Incorporated - Houston TX

International Classification:

E21B 23/01

US Classification:

166134, 166207, 166217

Abstract:

A slip for an expanding hanger or patch is disclosed. The slip is mounted over the hanger body and has an internal profile that nests within a mating profile on the exterior of the hanger. When a compressive force is applied to the hanger, it shrinks longitudinally and as a result the slip is cammed radially to the extent the inside diameter of the surrounding tubing permits. When the swage is advanced, the diameter of the hanger increases forcing the slip into preferably penetrating contact with the inside wall of the surrounding tubular.

US Classification:

525194, 525208, 525207, 525221, 525231, 525381

Abstract:

The present invention provides aqueous dispersions that, for example, include the reaction product of an oxirane-functional vinyl addition polymer having an oxirane functionality between 0. 5 and 5; an acid-functional polymer having an acid number 30 to 500; and a tertiary amine. Also described are coating compositions containing the dispersion and methods of forming the dispersion.

International Classification:

E21B 29/00

US Classification:

166380, 166384

Abstract:

A variety of approaches to reducing or eliminating “end effect” or the tendency of tubular ends to reduce in diameter after expansion are disclosed. Some involve pre-bending the ends outwardly while others involve removing material internally or/and externally near the ends. Yet other approaches feature weakening the ends in other ways including penetration of the tubular material using openings of various shapes including slots or/and holes where the openings are between the tube ends or where they can extend on one or both ends all the way to the end of the tubular. Inserts that are softer than the tube material can be placed near the ends. If there is an end effect, then the protruding material can be pushed out of the way or broken off.

International Classification:

E21B 43/10

US Classification:

166207, 166384

Abstract:

An apparatus to protect the mounting area of casing and a locating profile and optionally a sliding sleeve valve and a flow path from the outside of the valve to the annulus when subsequent attachment of an expanded liner is intended and the expanded liner is to be cemented in place. A barrier sleeve, nose, and outer sleeve define a sealed cavity having a loose incompressible material inside that covers the mounting location on the casing. A locating profile and an optional sliding sleeve valve and a flow path from the outside of the valve to the annulus can be provided. The cementing of the casing takes place through the barrier sleeve. After the cementing, the sleeve and nose are drilled out and the incompressible material is removed to the surface with the drill cuttings. A liner is inserted in the casing and is preferably expanded into sealing contact with the mounting location on the casing. After expansion a cement retainer positioned at the bottom of the expanded liner and the sliding sleeve located either above the mounting location of the liner in the casing shoe or in the liner below the mounted top section allow cement to be delivered outside the expanded liner and the displaced wellbore fluid to return into the casing through so that the liner can be cemented.
