Appl. No.:

11/473740

Inventors:

Edward T. Wood - Kingwood TX, US
Steven N. Bailey - College Station TX, US

Assignee:

Baker Hughes Incorporated - Houston TX

International Classification:

E21B 33/12

US Classification:

166179, 166387, 166300, 277331, 277934

Abstract:

A sealing element that swells on exposure to well fluids present or added to the wellbore is assembled to the mandrel in a manner to induce circumferential stresses proximately to the inside diameter of the element so as to resist the tendency of the inside diameter of the element to grow during the swelling process. A vacuum and a pressure method are described. Leak paths between the mandrel and the sealing element are minimized or eliminated as a result.

International Classification:

E21B 33/00
E21B 33/12

US Classification:

166387, 166132, 166179

Abstract:

A packer assembly which incorporates a swellable elastomeric packer element and one or more swellable thermoplastic components. The swellable thermoplastic components are support rings that are located at each axial end of the elastomeric element and provide positive mechanical backups for the elastomeric element to limit extrusion of the packer element.

Assignee:

BAKER HUGHES INCORPORATED - Houston TX

International Classification:

US Classification:

166249000, 166177200, 166067000

Abstract:

An apparatus includes a body shaped to deform a wellbore tool in a predetermined manner. A vibration device applies a vibration to the body to reduce a frictional force caused when the body deforms the wellbore tool. In one arrangement, the vibration devices imparts a resonant wave motion to a swaging apparatus that is being pushed through a passage of a wellbore tubular. A swaging body vibrates at a resonant frequency along the long axis of the wellbore tubular and/or normal to long axis of the wellbore tubular. The relative motion between the swaging body and the tubular member reduces the force required to expand the wellbore tubular. Optionally, a controller operatively connected to the vibration device adjusts the operation of the vibration device in response to the sensor measurements of the vibrations in the swage body.
