Filed:

Jun 12, 2008

Appl. No.:

12/137860

Inventors:

Robert S. O'Brien - Katy TX, US
Gerald D. Lynde - Houston TX, US
Yang Xu - Houston TX, US
Thomas Mathew - Houston TX, US

Assignee:

Baker Hughes Incorporated - Houston TX

International Classification:

B23P 19/02

US Classification:

29235, 29229, 29451

Abstract:

Disclosed herein is a method of installing an elastomeric element onto a tubular. The method includes, positioning the elastomeric element onto a radially expandable member, radially expanding the radially expandable member and the elastomeric element installed thereon, positioning a tubular coaxially with the radially expandable member, and axially urging the elastomeric element off the radially expandable member thereby allowing the elastomeric element to be positioned coaxially about an outer perimetrical surface of the tubular.

Abstract:

An electromyogram device () have a conformable housing () that houses or otherwise supports an electromyogram signal processor (), electromyogram sensors (), and a display () that provides, for example, information corresponding to one or more muscle condition parameters such as muscular fatigue. In various embodiments, the device can further include additional displays (), memory (), audible alarm mechanisms (), and/or a wireless receiver and/or transmitter (). In one embodiment, such devices can communicate amongst one another to permit central and/or remote display of the resultant electromyogram information.

Abstract:

Fine particulate polymer drag reducing agents (DRAs) in bi-modal or multi-modal particle size distributions may be produced simply and efficiently without cryogenic temperatures. The grinding or pulverizing of polymer, e.g. non-porous poly(alpha-olefin) suitable for reducing drag in hydrocarbons may be achieved by the use of at least one liquid grinding aid and at least two grinding processors in series. The blades of the stators of the grinders are of different configuration so that granulated polymer fed to the first processor having relatively larger gaps between blades is ground to an intermediate size which is fed to the second processor having relatively smaller gaps between blades which grinds the polymer to a second, smaller size. A non-limiting example of a suitable liquid grinding aid includes a blend of propylene glycol, water and hexanol. Particulate DRA may be produced at a size of 300 microns or less in only two passes.

International Classification:

E21B 33/13

US Classification:

166135

Abstract:

The annular space around a tubular string has a shape memory material that is in a low profile configuration for run in. After the desired position is obtained and the annulus has cement delivered to fill the annular space, the shape memory device is triggered to revert to an original shape that spans the annulus to seal the tubular and the wellbore sides of the annular space against gas migration through the cement. The structures can have varying run in shapes and can also have original shapes that when the material is triggered will act to displace cement to enhance its compaction on the tubular or the wellbore wall. Combinations of shape memory alloys and polymers are also contemplated to enhance the seal against gas migration.
